Patent Description:
Products such as mobile phones, tablet computers, and televisions, etc. are display devices that people often see in their daily life. They can not only facilitate people's work, but also display delightful pictures and add fun to people's life.

When the above display devices are in a display state, the displayed pictures not only have content needed by people, but also are accompanied by some information that comes with the display devices, for example, information about year, month, date, etc., so as to facilitate people to decide whether to watch the pictures displayed by the display devices according to the actual situation. However, when the display devices are in a standby state, not only the needed content cannot be displayed, but also some information that comes with the display devices cannot be displayed. For example, in the standby state, if people need to know the current time information via the display devices, it is necessary to re-awaken the display devices, such that the display devices are adjusted from the standby state to a normal display state, and only in this way, can the time information be obtained. However, the power consumption required for awakening the display devices is high, and frequent awakening of the display devices will also cause a large hardware loss to the display devices.

The display drive circuit may be configured to select a part of the image data and output the selected part to a designated region of the display. So, a self-display can be realized.

<CIT> relates to a mobile operation system comprising an intelligent dynamic icon, a quick voice assistant, a quick sliding assistant, an intelligent gesture, a full-screen application program interface, a full-domain application program icon interface, a quick full close and an important contact person program. According to the intelligent dynamic icon, icons of application programs in an updating state are automatically displayed on a main interface. By means of the quick voice assistant, the application programs can be directly started through voice without the internet. After the quick sliding assistant slides a regular shape on the main interface, the application programs can be directly started. The application programs can be direction started through the intelligent gesture according to movements of the user. According to the intelligent gesture, when the user takes out a mobile phone from a pocket, the system can be automatically waken up and automatic sliding unlocking can be achieved.

<CIT> relates to a method of unlocking a locking mode of a portable terminal, which includes sensing a user's gesture input which is set in a locking mode of the portable terminal. The locking mode is unlocked in response to the user's gesture input, and a function mapped to the user's gesture can be executed when unlocking the locking mode. A portable terminal compares gestures among predefined sets of gesture information in order to check whether there is a gesture that coincides with the analyzed gesture.

<CIT> relates to a selective rejection of touch contacts in an edge region of a touch sensor panel. In addition, by providing certain exceptions to the rejection of edge contacts, the functionality of the touch sensor panel can be maximized. Contacts in edge bands around the perimeter of a touch sensor panel can be ignored. However, if a contact in the edge band moves beyond a threshold distance or speed, it can be recognized as part of a gesture. To accommodate different finger sizes, the size of the edge band can be modified based on the identification of the finger or thumb. Furthermore, if contacts in the center region of a touch sensor panel track the movement of contacts in the edge band, the contacts in the edge band can be recognized as part of a gesture.

In the following the technical solutions in embodiments of the disclosure will be described clearly and completely in conjunction with the drawings in the embodiments of the disclosure.

With reference to <FIG>, a display device provided by an embodiment of the disclosure includes a display panel and a display controller, the display controller includes a display driver <NUM>, a data storage <NUM>, a mode trigger <NUM> and a mode controller <NUM> for controlling the display panel to be in a normal display mode or a standby display mode, the output terminal of the mode trigger <NUM> is connected with the input terminal of the mode controller <NUM>, the output terminal of the mode controller <NUM> is connected with the control terminal of a signal switcher <NUM> and the control terminal of the display driver <NUM>, respectively, the output terminal of the signal switcher <NUM> is connected with a normal display signal terminal <NUM> and a standby display signal terminal <NUM> connected with the data storage <NUM>, respectively, and the normal display signal terminal <NUM> and the standby display signal terminal <NUM> are connected with the input terminal of the display driver <NUM>, respectively.

In a specific implementation, when it is needed to display information that comes with the display device in a standby condition, the mode trigger <NUM> sends out a first trigger electrical signal to the mode controller <NUM>, such that the mode controller <NUM> controls the operation of the display driver <NUM> according to the first trigger electrical signal, and the signal switcher <NUM> causes the standby display signal terminal <NUM> to provide a standby display signal to the display driver <NUM> according to the first trigger electrical signal, which standby display signal is information stored by the data storage <NUM> which comes with the display device.

When normal display is needed, a second trigger electrical signal is sent out to the mode controller <NUM> via the mode trigger <NUM>, such that the mode controller <NUM> controls the operation of the display driver <NUM> according to the second trigger electrical signal, and the signal switcher <NUM> causes the normal display signal terminal to provide a normal display signal according to the second trigger electrical signal.

It may be found out based on the structure of the display device that the output terminal of the mode trigger <NUM> is connected with the input terminal of the mode controller <NUM>, such that the mode trigger <NUM> can trigger the mode controller <NUM> for mode selection, the output terminal of the mode controller <NUM> is connected with the control terminal of the signal switcher <NUM> and the control terminal of the display driver <NUM>, respectively, the output terminal of the signal switcher <NUM> is connected with the normal display signal terminal <NUM> and the standby display signal terminal <NUM> connected with the data storage <NUM>, respectively, and the normal display signal terminal <NUM> and the standby display signal terminal <NUM> are connected with the input terminal of the display driver <NUM>, respectively, such that when normal display is needed, a first trigger electrical signal is sent to the mode controller <NUM> via the mode trigger <NUM>, such that the mode controller <NUM> controls the display driver <NUM> according to the first trigger electrical signal, when standby display is needed, the signal switcher <NUM> is controlled by the mode controller <NUM>, such that the standby display signal terminal <NUM> provides a standby display signal with the display driver <NUM>, and as such, it is possible to trigger the standby display mode via the mode trigger in a standby state, to display information content (e.g., year, month, date) that comes with the display device which is provided via the standby display signal terminal <NUM> by the data storage, whereas display of the information content that comes with the display device needs to cause the display driver <NUM> to drive all the pixels of the display panel to work, so for the display device provided by the disclosure in the standby state, it is only necessary to trigger the standby display mode via the mode trigger <NUM>, which reduces the power consumption of the display device when the display device displays its own information and the hardware loss of the display device.

It may be appreciated that the data storage <NUM> in the above embodiment may be a memory of the display device, or also may be an additionally connected data storage <NUM> which is connected with a timer to store time information calculated by the timer in real time. Of course, the data storage <NUM> is not only limited to storing information that comes with the display device, and also may store a normal display signal when in normal display.

In an embodiment, the display controller in the above-described embodiment further includes a trigger identifier <NUM>, and the output terminal of the mode trigger <NUM> is connected with the input terminal of the mode controller <NUM> via the trigger identifier <NUM>, such that when the mode trigger <NUM> sends out a first trigger signal, it is possible to perform confirmation of the trigger signal via the trigger identifier <NUM>, guaranteeing the accuracy and authenticity of the inputted first trigger signal.

In the following, a specific implementation structure and an identification principle of the trigger identifier <NUM> will be exemplified in connection with <FIG> and <FIG>.

A first implementation structure is as shown in <FIG>. The trigger identifier <NUM> includes a counting relay <NUM> and a first numerical comparator <NUM>, and the mode trigger <NUM> is a preset key <NUM>, and the preset key <NUM> is connected with the input terminal of the counting relay <NUM>, a first input terminal of the first numerical comparator <NUM> is connected with the output terminal of the counting relay <NUM>, a second input terminal of the first numerical comparator <NUM> is connected with a first reference signal terminal <NUM>, and the output terminal of the first numerical comparator <NUM> is connected with the input terminal of the mode controller <NUM>. The preset key <NUM> may be any switch key on the display device, or also may be an additionally connected key, or also may be a "home" key in the display device.

At this point, since the preset key <NUM> is connected with the input terminal of the counting relay <NUM>, and in turn, the first input terminal of the first numerical comparator <NUM> is connected with the output terminal of the counting relay <NUM>, the second input terminal of the first numerical comparator <NUM> is connected with the first reference signal terminal <NUM>, and the output terminal of the first numerical comparator <NUM> is connected with the input terminal of the mode controller <NUM>, the counting relay <NUM> may identify the pressing number of times of the preset key <NUM>, and the first numerical comparator <NUM> may compare the pressing number of times of the preset key <NUM> identified by the counting relay <NUM> with a reference signal provided by the first reference signal terminal <NUM>, to send out a first trigger electrical signal to the mode controller <NUM> when the pressing number of times of the preset key <NUM> is equal to the reference signal, such that the mode controller <NUM> controls the display panel to be in the standby display mode, and to send out a second trigger electrical signal to the mode controller <NUM> when the pressing number of times of the preset key <NUM> is greater than the reference signal, such that the mode controller controls the display panel to be in the normal display mode.

A second implementation structure is as shown in <FIG>. The trigger identifier <NUM> in the above-described embodiment includes an angle identifier <NUM> and a second numerical comparator, and the mode trigger <NUM> includes a direction sensor <NUM> and a preset key <NUM>, the output terminal of the direction sensor <NUM> is connected with the input terminal of the angle identifier <NUM>, a first input terminal of the second numerical comparator is connected with the output terminal of the angle identifier <NUM>, a second input terminal of the second numerical comparator is connected with a second reference signal terminal, and the output terminal of the second numerical comparator and the preset key <NUM> are connected with input terminals of the mode controller <NUM>, respectively, and the preset key <NUM> may be any switch key on the display device, or also may be an additionally connected key, or also may be a "home" key in the display device.

At this point, since the output terminal of the direction sensor <NUM> is connected with the input terminal of the angle identifier <NUM>, the first input terminal of the second numerical comparator is connected with the output terminal of the angle identifier <NUM>, the second input terminal of the second numerical comparator is connected with the second reference signal terminal <NUM>, and the output terminal of the second numerical comparator is connected with an input terminal of the mode controller <NUM>, the direction sensor <NUM> may identify the direction of the display device, and the angle which the display device is at is identified by the angle identifier <NUM>, and then the second numerical comparator is utilized to compare the angle which the display device is at and a reference signal provided by the second reference signal terminal <NUM>, to provide a first trigger electrical signal to the mode controller <NUM> in a condition in which they are equal, such that the mode controller <NUM> controls the display panel to be in the standby display mode, and not to send out a trigger electrical signal in a condition in which the pressing number of times of the preset key <NUM> is greater than the reference signal, and the standby state is kept. As for a specific process of the mode controller <NUM> controlling the display panel to be in the standby display mode, please refer to the forgoing description.

On the other hand, since the preset key <NUM> is connected with an input terminal of the mode controller <NUM>, when normal display is needed, a second trigger electrical signal is sent out to the mode controller <NUM> by pressing the preset key <NUM>, such that after the mode controller <NUM> receives the second trigger electrical signal, the mode controller <NUM> controls the display panel to be in the normal display mode. As for a process of the mode controller <NUM> controlling the display panel to be in the normal display mode, please refer to the forgoing description.

In an example, the direction sensor <NUM> is a three-dimensional gyroscope or an angular velocity sensor, and the angle identifier <NUM> is an angular velocity integration circuit for converting an angular velocity into a rotation angle, in order to utilize the angular velocity integration circuit to convert an angular velocity sensed by the three-dimensional gyroscope or the angular velocity sensor into a rotation angle.

A third implementation structure is as shown in <FIG>. The display panel is a touch-typed display panel, the mode trigger <NUM> is a touch detector <NUM> and a preset key <NUM>, the trigger identifier <NUM> includes a first logic AND gate operation circuit <NUM> and a light sensor <NUM> for detecting the light of the display surface of the touch-typed display panel, the output terminal of the light sensor <NUM> is connected with a first input terminal of the first logic AND gate operation circuit <NUM>, the output terminal of the touch detector <NUM> is connected with a second input terminal of the first logic AND gate operation circuit <NUM>, and the output terminal of the first logic AND gate operation circuit <NUM> and the preset key <NUM> are connected with input terminals of the mode controller <NUM>, respectively, and the preset key <NUM> may be any switch key on the display device, or also may be an additionally connected key, or also may be a "home" key in the display device.

At this point, since the output terminal of the touch detector <NUM> is connected with an input terminal of the mode controller <NUM>, in an electrode condition, it is only necessary to touch the touch-typed display panel, such that the touch detector <NUM> detects a touch signal and sends it to the mode controller <NUM> in the form of a first trigger electrical signal, such that the mode controller <NUM> controls the touch-typed display panel to be in the standby display mode. As for a process of the mode controller <NUM> controlling the touch-typed display panel to be in the standby display mode, please refer to the forgoing description. On the other hand, since the preset key <NUM> is connected with an input terminal of the mode controller <NUM>, when normal display is needed, the preset key <NUM> is caused to send a second trigger electrical signal by pressing the preset key <NUM>, and when the mode controller <NUM> receives the second trigger electrical signal, the mode controller <NUM> controls the touch-typed display panel to be in the normal display mode. As for a process of the mode controller <NUM> controlling the touch-typed display panel to be in the normal display mode, please refer to the forgoing description.

In addition, considering that the touch-typed display panel is touched by mistake under a certain circumstance, for example, the touch-typed display panel keeps the state of being touched all the time when a hand(s) holds/hold the touch-typed display panel, and at this moment, there is no light inside the touch-typed display panel, an embodiment of the disclosure further introduces a light sensor <NUM> for detecting the light of the display surface of the touch-typed display panel, and since the output terminal of the touch detector <NUM> is connected with an input terminal of a second logic AND gate operation circuit <NUM>, and the output terminal of the first logic AND gate operation circuit <NUM> is connected with an input terminal of the mode controller <NUM>, the light sensor <NUM> may detect whether the display screen of the touch-typed display panel has light, and if the first logic AND gate operation circuit <NUM> outputs an electrical signal, it indicates that the light sensor <NUM> has detected light and the touch detector <NUM> has identified touch information, and at this point, the electrical signal outputted by the first logic AND gate operation circuit <NUM> may be utilized to control the mode controller <NUM>, to cause the display panel to be in the standby display mode.

If the first logic AND gate operation circuit <NUM> has no electrical signal to be outputted, and the touch detector <NUM> detects information, it indicates that the light sensor <NUM> has not detected light, and at this moment, the first logic AND gate operation circuit <NUM> cannot control the mode controller <NUM> to cause the display panel to be in the standby display mode.

Exemplarily, as shown in <FIG>, the touch detector <NUM> in the above-described embodiment is a gesture identifier or a fingerprint identifier, the trigger identifier <NUM> further includes a second logic AND gate operation circuit <NUM>, a first input terminal of the second logic AND gate operation circuit <NUM> is connected with the output terminal of the touch detector <NUM>, and a second input terminal of the second logic AND gate operation circuit <NUM> is connected with a third reference signal terminal <NUM>, and the output terminal of the second logic AND gate operation circuit <NUM> is connected with the second input terminal of the first logic AND gate operation circuit <NUM>.

When the touch detector <NUM> is a gesture identifier, it can further be judged by the second logic AND gate operation circuit <NUM> whether the touch gesture is identical to a preset gesture signal provided by the third reference signal terminal <NUM>, so as to input a first trigger electrical signal to the first logic AND gate operation circuit <NUM> when they are identical, and on the other hand, when the touch detector <NUM> is a fingerprint identifier, it can be judged by the second logic AND gate operation circuit <NUM> whether the touch fingerprint is identical to a preset fingerprint signal provided by the third reference signal terminal <NUM>, so as to input a first trigger electrical signal to the first logic AND gate operation circuit <NUM> when they are identical.

Here, it needs to be noted that the above third reference signal terminal <NUM> may be selected to be connected with a different storage depending on the touch detector <NUM>. If the touch detector <NUM> is a gesture identifier, the third reference signal terminal <NUM> is connected with a preset fingerprint storage, to provide a preset fingerprint signal to the second logic AND gate operation circuit <NUM>, and if the touch detector <NUM> is a gesture identifier, the third reference signal terminal <NUM> is connected with a preset gesture storage, to provide a preset gesture signal to the second logic AND gate operation circuit <NUM>.

Further, as shown in <FIG>, the trigger identifier <NUM> further includes a touch locator <NUM>, the output terminal of the touch detector <NUM> is further connected with the input terminal of the touch locator <NUM>, and the output terminal of the touch locator <NUM> is connected with the input terminal of the mode controller <NUM>, such that in the standby display, after receiving location information sent out by the touch locator <NUM>, the mode controller <NUM> controls the display driver <NUM> to drive the touch-typed display panel for standby display.

Further, as shown in <FIG>, the standby display may further be performed according to the touch position in the above embodiments. For example, when an arc area of <FIG> is touched, the content displayed by the standby display will show the arc area.

In an embodiment, as shown in <FIG>, the touch-typed display panel is a touch-typed liquid crystal display panel, which includes a standby display area located in a normal display area A, the display device further includes a backlight module, which includes m normal display light sources <NUM> for corresponding to the normal display area A, the display controller further includes a backlight control apparatus <NUM>, which includes a backlight controller <NUM>, a power supply <NUM> and m electromagnetic switches <NUM> for power supply which are connected with the power supply <NUM>, and the m electromagnetic switches <NUM> for power supply are in one-to-one correspondence connection with the m normal display light sources <NUM>, and the output terminal of the mode controller <NUM> is further connected with the input terminal of the backlight controller <NUM>, and the output terminal of the backlight controller <NUM> is connected with the control terminals of the m electromagnetic switches <NUM> for power supply, respectively.

In a specific implementation, the mode controller <NUM> sends touch position information to the backlight controller <NUM>, such that the backlight controller <NUM> controls electromagnetic switches for power supply corresponding to the touch position to be closed, to light normal display light sources corresponding to the electromagnetic switches for power supply, such that standby display is performed on the corresponding touch position of the display panel, and such an area for standby display is defined as a variable standby display area.

As shown in <FIG>, when the touch-typed liquid crystal display panel is touched the first time, the normal display light sources framed by the dotted box in <FIG> are lit, and there is a first variable standby display area B <NUM> on the touch-typed liquid crystal display panel accordingly, which first variable standby display area B1 corresponds to the normal display light sources framed by the dotted box in <FIG>.

Of course, when the standby display is implemented by the display device provided by the above embodiments, it may also be possible to fix the area for standby display, and the standby display area which is fixed is called a fixed standby display area B0 (see <FIG> and <FIG>), and at this point, this may be implemented by the following two structures.

In a first structure, as shown in <FIG> and <FIG>, the display panel is a liquid crystal display panel, which includes a standby display area located in a normal display area A, which standby display area is called a fixed standby display area B0, the display device further includes a backlight module, which includes m normal display light sources <NUM> for corresponding to the normal display area A, k normal display light sources 6a correspond to the fixed standby display area B0 as k standby display light sources, the display controller further includes a backlight control apparatus <NUM>, which includes a standby backlight controller <NUM>, a power supply <NUM> and m electromagnetic switches <NUM> for power supply which are connected with the power supply <NUM>, the m normal display light sources <NUM> are in one-to-one correspondence connection with the m electromagnetic switches <NUM> for power supply, and <NUM> < k < m.

The output terminal of the mode controller <NUM> is further connected with the control terminals of the m electromagnetic switches <NUM> for power supply and the input terminal of the standby backlight controller <NUM>, respectively, and the output terminal of the standby backlight controller <NUM> is connected with control terminals of k electromagnetic switches 83a for power supply corresponding to the k normal display light sources 6a as the k standby display light sources, respectively, such that when the mode controller <NUM> receives a first trigger electrical signal, the mode controller <NUM> controls the standby backlight controller <NUM> to send out a signal to the electromagnetic switches for power supply corresponding to the k normal display light sources as standby display light sources, such that the k electromagnetic switches 83a for power supply corresponding to the k normal display light sources 6a as the k standby display light sources are closed, thereby lighting the k normal display light sources 6a as the k standby display light sources to realize standby display in the fixed standby display area B0, and on the other hand, when the mode controller <NUM> receives a second trigger electrical signal, the mode controller <NUM> controls the m electromagnetic switches <NUM> for power supply to be closed, such that the m normal display light sources <NUM> are lit, thereby realizing normal display.

Exemplarily, as shown in <FIG>, the second side of the light guide diaphragm where the k standby display light sources <NUM> are located may be opposite or adjacent to the first side of the light guide diaphragm.

As shown in <FIG>, the display controller further includes a backlight control apparatus <NUM>, which includes a standby backlight controller <NUM> and a normal backlight controller <NUM>, the output terminal of the mode controller <NUM> is connected with the control terminal of the standby backlight controller <NUM> and the input terminal of the normal backlight controller <NUM>, respectively, and the output terminal of the normal backlight controller <NUM> is connected with the m normal display light sources, respectively, and the output terminal of the standby backlight controller <NUM> is connected with the k standby display light sources, respectively, at this point, when the mode controller <NUM> receives a first trigger electrical signal, the mode controller controls the standby backlight controller <NUM> to light the k standby display light sources <NUM>, to realize standby display of the fixed standby display area B0, and on the other hand, when the mode controller receives a second trigger electrical signal, the mode controller controls the normal backlight controller <NUM> to light the m normal display light sources, to realize normal display.

In addition, the standby backlight controller <NUM> and the normal backlight controller <NUM> in the above embodiment are equivalent to electrically controlled switches, and it is only necessary to light corresponding display light sources after receiving a corresponding signal without the need for special method improvement. This may be implemented by for example electromagnetic switches in the prior art.

It needs to be noted that, in the above embodiments, there are various structures for the signal switcher <NUM>. In the following, a specific structure will be given and its switching principle will be elucidated.

As shown in <FIG>, the signal switcher <NUM> in the above embodiments includes an electromagnetic switch for standby display <NUM> and an electromagnetic switch for normal display <NUM>, the electromagnetic switch for standby display <NUM> is arranged on the standby display signal terminal <NUM>, the electromagnetic switch <NUM> for normal display is arranged on the normal display signal terminal <NUM>, and the output terminal of the mode controller <NUM> is connected with the control terminal of the electromagnetic switch for standby display <NUM> and the control terminal of the electromagnetic switch for normal display <NUM>, respectively.

When the mode controller <NUM> receives a first trigger electrical signal, the mode controller <NUM> controls the electromagnetic switch for standby display <NUM> to be closed, such that a standby display signal stored in the data storage <NUM> may be provided to the display driver <NUM> via the standby display signal terminal <NUM>, and when the mode controller <NUM> receives a second trigger electrical signal, the mode controller <NUM> controls the electromagnetic switch for normal display <NUM> to be closed, such that a normal display signal may be provided to the display driver <NUM> via the normal display signal terminal <NUM>.

The display driver <NUM> is an existing display driver, as shown in <FIG>, which includes a timing controller <NUM>, a data driver <NUM> and a gate driver <NUM>, the display panel includes at least an array substrate, which includes an arrayed thin film transistor, the output terminal of the mode controller <NUM> is connected with the control terminal of the timing controller <NUM>, the normal display signal terminal <NUM> and the standby display signal terminal <NUM> are connected with the input terminal of the timing controller <NUM>, respectively, the output terminal of the timing controller <NUM> is connected with the input terminal of the data driver <NUM> and the input terminal of the gate driver <NUM>, respectively, the output terminal of the data driver <NUM> is connected with the signal input terminal of the arrayed thin film transistor, and the output terminal of the gate driver <NUM> is connected with the control terminal of the arrayed thin film transistor.

In standby display, the mode controller <NUM> receives a first trigger electrical signal, controls the timing controller <NUM>, and starts the timing controller <NUM>, such that the timing controller <NUM> receives a standby data signal and transmits it to the gate driver <NUM> and the data driver <NUM> for display. In normal display, the mode controller <NUM> receives a second trigger electrical signal, and controls the timing controller <NUM>, such that the timing controller <NUM> receives a normal data signal for display.

In addition, when the gate driver <NUM> is a gate drive circuit (a GOA circuit), the gate drive circuit is produced on the array substrate, and the gate drive circuit will successively turn on each row of thin film transistors in the array substrate, whether in standby display or in normal display. However, in standby display, the data driver <NUM> will only provide the standby data signal to several fixed columns of data lines, and therefore, in standby display, although the gate drive circuit will successively turn on each row of thin film transistors in the array substrate, not every thin film transistor in the array substrate will work.

As compared to the prior art, for the display controller and the display device provided by the disclosure, it is only necessary to trigger the standby display mode by the mode trigger in the standby state, which reduces the power consumption of the display device and the hardware loss of the display device when the display device displays its own information.
