[0011] FIG. 1 is a schematic diagram of a micro LED control device 30 comprising a substrate 25, a motor 35 operatively connected to the substrate 25, a support stand 40 connected to the motor 35, a support plate 45 on the support stand 40, and a micro LED 50 on the support plate 45, wherein the motor 35 is set to rotate the support stand 40. The substrate 25 may be rigid or flexible and may comprise any of sapphire, silicon carbide, silicon, and gallium nitride materials, for example. The motor 35 may be a micro electric engine. Examples of micro electric engines include a linear resonant actuator (LRA), a planetary and spur reduction gear motor, a low voltage vibration motor, and a DC motor including brushless motors, among other types of motors.
[0012] The support stand 40 is configured as a structural frame, which may comprise conductive material. In one example, the support stand 40 includes amorphous metal alloys. The support stand 40 may be connected to the motor 35 using any suitable mechanism available to structurally connect the support stand 40 to the rotor of the motor 35. The rotor is not shown in the drawings, but would be readily apparent to include the moving part of the motor 35 that drives the rotation of the connected support stand 40. The connection of the support stand 40 to the motor 35 may be a direct connection or an indirect connection utilizing intervening components. The support plate 45 may comprise a conductive material in one example. In another example, the support plate 45 may comprise glass or other type of transparent material such as quartz, plastic, semiconductors, among other types of materials.
[0014] The micro LED 50 may comprise a mono or multi-color micro LED 50. The support stand 40 comprises a sub-pixel driving circuit 55. In one example, the sub-pixel driving circuit may comprise electrical control circuitry, which may include, without limitation, digital-to-analog converters, multiplexers, arithmetic circuits, and logic modules that are powered by a voltage source and transmit electrical signals to drive the display action of pixels.
[0015] FIG. 3, with reference to FIGS. 1 and 2, is a schematic diagram of a micro LED pixel display system 10, according to an example herein. The micro LED pixel display system 1 0 comprises a plurality of sensors 1 5, a display screen 20 adjacent to the plurality of sensors 1 5, wherein the display screen 20 comprises a substrate 25, and a micro LED control device 30. The plurality of sensors 15 may comprise infrared iris recognition sensors and may be positioned at various locations on an electronic device 1 2. In various examples, the sensors 1 5 may be positioned on the front or back of the display screen 20. While the figures depict the electronic device 12 as a laptop computer, the examples herein are not restricted to only a laptop computer. Accordingly, other types of electronic devices having displays may be utilized in accordance with the examples described herein. The substrate 25 may comprise the substrate of the display screen 20, in one example, with the micro LED control device 30 built on and including the substrate 25. In other examples, the substrate 25 may constitute a discrete component separate from the micro LED control device 30.
[0016] A support member 31 operatively connects the motor 35 to the substrate 25. In one example, the support member 31 may comprise soldering. The plurality of sensors 15, which may comprise infrared iris recognition sensors, are set to detect eye movements of a user 17. In one example, the plurality of sensors 15 scan the eyes of the user 17 and uses mathematical pattern-recognition software, either stored locally on the electronic device 12 or remotely delivered to the electronic device 12 using firmware, to identify the eye patterns, shapes, color, etc. of the user 17. Once the plurality of sensors 15 visually detect the eyes of the user 17, the plurality of sensors 15 deliver a signal, such as an electrical signal, to the sub-pixel driving circuit 55 based on the detected eye movements of the user 17. In this regard, the plurality of sensors 15 not only detect the appearance of the eyes of the user 1 , but also detect the movements of the eyes of the user 17. More particularly, when the user 17 moves his/her head at various angles in relation to the electronic device 12, the plurality of sensors 15 detect the corresponding movements of the eyes of the user 17. In one example, if the sensors 15 are finely tuned, then they may detect the eye movements of the user 17 even when the user does not move his/her head and simply moves their eyes. Accordingly, the user 17 does not have to move his/her head at all, and instead the electronic device 12 may be moved in relation to the stationary user 17 upon detecting changes in the position and location of the eyes of the user 17 relative to the electronic device 12. As such, the plurality of sensors 15 similarly attempt to detect the eyes of the user 17.
[0017] After the plurality of sensors 15 deliver the signal to the sub-pixel driving circuit 55, then the sub-pixel driving circuit 55 instructs the motor 35 to rotate in a prescribed direction based on the position of the eyes of the user 17 in relation to the display screen 20. More specifically, the sub-pixel driving circuit 55 sends a corresponding signal, such as an electrical signal, to the motor 35 to begin tilting; i.e., rotating, in a specified direction towards the detected position of the eyes of the user 17. For example, if the user 17 is positioned to the left of the display screen 20 of the electronic device 12, then the sensors 15, in addition to detecting the eyes of the user 17, also detect the relative position of the eyes of the user 17 as being to the left of the electronic device 12, and send a corresponding first electrical signal to the sub-pixel driving circuit 55, which in turn sends a corresponding second electrical signal to the motor 35 to begin rotating towards the position of the user 17; i.e., the motor 35 begins rotating to the left. FIG. 3 illustrates an example of the micro LED control device 30 being initially positioned in a straight configuration; i.e. 0° rotation, and then the corresponding rotation of approximately 45° to the left based on the corresponding position of the user 17, who is depicted as being to the left of the electronic device 12.
[0018] The display screen 20 comprises a pixel area 60 comprising an array 65 of pixels 50a, 50b, 50c, wherein each pixel area 60 of the array 65 of pixels 50a, 50b, 50c comprises a plurality of micro LED control devices 30a, 30b, 30c. The micro LED control devices 30a, 30b, 30c respectively comprise a different color with respect to the light that is transmitted from the particular device 30a, 30b, 30c. In one example, each micro LED control device 30a, 30b, 30c comprises a different translucent colored filter 32a, 32b, 32c respectively corresponding to red (R), green (G), and blue (B) colors such that when light from a micro LED 50, as depicted in FIG. 4, is transmitted through the filter 32a, 32b, 32c, the transmitted light becomes the corresponding color; i.e., red, green, or blue. The micro LED 50 may be positioned below the filter 32a, 32b, 32c, or within the filter 32a, 32b, 32c if the filter 32a, 32b, 32c is configured as a capsule-like mechanism. FIG. 4, with reference to FIGS. 1 through 3, illustrates rotation of the micro LED control device 30 in relation to the movement or position of the eyes of a user 17. The micro LEDs 50 are positioned in the filters 32a, 32b, 32c to transmit light towards the user 17 since the micro LED control device 30 is positioned towards the user 17. In another example, the micro LEDs 50 may comprise different multi-color LEDs such that filters 32a, 32b, 32c may not necessarily be colored in accordance with the red, green, blue configuration. In another example, the micro LEDs 50 are multi-colored and the filters 32a, 32b, 32c are also colored in accordance with the red, green, blue configuration. The various combination of mono/multi-color LEDs 50 with non- colored or colored filters 32a, 32b, 32c controls the overall color that is transmitted from the pixels 50a, 50b, 50c, respectively.
[0019] FIG. 5, with reference to FIGS. 1 through 4, illustrates that the plurality of micro LED control devices 30a, 30b, 30c, which comprise a first micro LED control device 30a, a second micro LED control device 30b, and a third micro LED control device 30c, may move independently with respect to one another. For example, the first micro LED control device 30a may be rotated to a first angle θι, the first micro LED control device 30a may be rotated to a second angle θ∑, and the first micro LED control device 30a may be rotated to a third angle Θ3 such that the first angle Θ1, second angle Θ2, and third angle Θ3 may be different from one another. In other examples, the plurality of micro LED control devices 30a, 30b, 30c move uniformly with one another; i.e., such that the first angle Θ1, second angle Θ2, and third angle Θ3 are the same.
[0020] FIG. 6, with reference to FIGS. 1 through 5, is a schematic diagram illustrating a system 10a comprising a plurality of infrared iris recognition sensors 15, an electric circuit 55 set to receive a first set of electrical signals from the plurality of infrared iris recognition sensors 15, a conductive support frame; e.g., support stand, 40 comprising the electric circuit 55, a micro LED pixel 50a, 50b, 50c attached on the conductive support frame 40, and a micro electric engine 35 operatively connected to the electric circuit 55 and conductive support frame 40, wherein the micro electric engine 35 rotates the conductive support frame 40 and the attached micro LED pixel 50a, 50b, 50c upon receiving a second set of electrical signals from the electric circuit 55 based on the first set of electrical signals received from the plurality of infrared iris recognition sensors 15.
[0021] The micro electric engine 35 is set to rotate the conductive support frame 40 approximately forty-five degrees (45°) in each lateral direction with respect to a two-dimensional rotation plane x-y. The plurality of infrared iris recognition sensors 15 are set to detect eye movements of a computerized device user 17. The first set of electrical signals comprise encoded data related to directional position of the eyes of the user 17 in relation to the plurality of infrared iris recognition sensors 15. The second set of electrical signals comprise encoded data that corresponds the direction of rotation of the micro electric engine 35 to the directional position of the eyes of the user 17. The system 10 may comprise a power unit 75 set to power off the micro LED 50 upon the plurality of infrared iris recognition sensors 15 failing to detect eyes of a computerized device user 17. System 10a includes all of the features of system 10. However, in system 10a only a pair of infrared iris recognition sensors 15 are provided compared with the plurality of pairs of sensors 15 in FIG. 3. In various examples, the pair of infrared iris recognition sensors 15 may be positioned on the front or back of the screen 20. Moreover, the power unit 75 may also be part of system 10 in one example.
[0022] The system 10a may comprise a display screen 20, wherein the plurality of sensors 15 are set to deliver the first set of electrical signals to the electric circuit 55 based on detected eye movements of the user 17, and wherein the electric circuit 55 instructs the micro electric engine 35 to rotate in a prescribed direction based on the position of the eyes of the user 17 in relation to the display screen 20.
[0023] FIG. 7, with reference to FIGS. 1 through 6, is a flowchart illustrating a method 100 comprising sensing an ambient light intensity of an area adjacent to an electric display screen 20 as shown in block 101 . Next, in block 103 the method 100 includes detecting a pupil of a user 17 using iris recognition detection sensors 15 located adjacent to the electric display screen 20. Block 105 provides for delivering an electrical signal to a micro LED pixel display 60 embedded in the electric display screen 20, wherein the electrical signal comprises encoded data corresponding to a position of the pupil of the user 17 in relation to the electric display screen 20. Block 107 provides for controlling the rotation of the micro LED pixel display 60 according to the electrical signal relating to the movement of the eye of the user 17, and block 109 shows the method 100 comprising rotating the micro LED pixel display 60 at a plurality of angles to adjust a field-of-view for the electric display screen 20. The method comprises rotating the micro LED pixel display 60 approximately forty-five degrees, 45°, in each lateral direction with respect to a two- dimensional rotation plane x-y. A complete 90° angle of rotation of the micro LED pixel display 60 may occur in approximately one second. For example, with reference to FIG. 4, the micro LED control device 30 may transition from the tilted position shown on the left side of FIG. 4 to the tilted position shown on the right side of FIG. 4 in approximately one second, wherein a complete 90° angle of rotation may occur from the left side image to the right side image in FIG. 4.
[0024] By rotating, the micro LED control device 30 is able to transmit light from the LEDs 50 towards the direction of a user 17. In this regard, if a user is positioned to the side of the electronic device 12, then the sensors 15 attempt to search for the eyes of the user 17. Once the sensors 15 make visual contact with the eyes of the user 17, then the corresponding transmission of electrical signals occurs; i.e., from the sensors 15 to the sub-pixel driving circuit 55, and then from the sub-pixel driving circuit 55 to the motor 35 causing rotation of the motor 35 and the corresponding connected support stand 40, support plate 45, and micro LED 50 towards the user 17.
[0025] In one example, because the micro LED 50 is angled only in one direction; i.e., towards the user 17, the display screen 20 will appear dark or otherwise having less visual acuity when viewed at an angle not aligned with the user 17. Accordingly, if the user 17 is positioned next to another person and the user 17 moves his/her head to the left or right, then the sensors 15 detect this movement by detecting the movement and position of the eyes of the user 17 and rotate the micro LED control device 30 accordingly. An adjacent person who is positioned next to the user 17 would see a dark screen when attempting to view the display screen 20 because the micro LEDs 50 are not transmitting light in the direction of the adjacent person. In another example, the power unit 75 may power off the micro LED 50 upon the sensors 15 failing to detect eyes of the user 17, after a predetermined period of time. This results in the display screen 20 going dark and thus no data or images on the display screen 20 are viewable at any angle relative to the display screen 20.
[0026] FIG. 8, with reference to FIGS. 1 through 7, illustrates a block diagram of a control system 120 that provides for an automatic screen viewing angle adjustment solution by detecting and recognizing the degree of difference of constricting and dilating responses on the eye pupils of a user 17 through infrared iris recognition and identification sensors 15 and corresponding iris recognition software modules 123 in order to have automatic and real-time micro LED eye-contact control of the display screen 20 based on the user's eye directional movement and position. The micro engine control 122, as enabled by the micro LED control device 30, may combine the data compiled by sensor modules 125, which receive the data provided by sensors 15, with automated biometric identification information stored in memory 124 for a given user 17 to provide user verification for secured access of the electronic device 12 and the contents displayed on the screen 20. Accordingly, the micro engine control 122 provides for enhanced and secured viewing of the display screen 20 as the user 17 reads and operates the screen 20 from different directions. For example, the user 17 may be reading from a book or set of papers and is constantly glancing back-and-forth between the display screen 20 and the set of papers. The micro engine control 122 assesses when the user 17 is actually looking at the screen 20 and adjusts the direction and transmission of the light from the micro LED 50 accordingly. This allows pixels 50a, 50b, 50c to be viewable only at the corresponding angle where the eyes of the user 17 are positioned/aligned with the screen 20. For enhanced information protection and security purposes, the iris recognition modules 123 may be programmed to recognize the eyes of only a particular user 17 that has previously signed-on with the system 10, 10a through a secured credentialed process including password entry and/or facial recognition or other biometric recognition process.
[0027] The iris recognition modules 123 and sensor modules 125 may include hardware and software elements to enable the proper pattern matching of the detected eyes of the user 17 with the images of the eyes of the user 17 stored in memory 124. Accordingly, various examples herein can include both hardware and software elements. The examples that are implemented in software include but are not limited to, firmware, resident software, microcode, etc. Other examples may include a computer program product configured to include a pre-configured set of instructions, which when performed, can result in actions as stated in conjunction with the methods described above. In an example, the pre-configured set of instructions can be stored on a tangible non- transitory computer readable medium or a program storage device containing software code.
[0028] The present disclosure has been shown and described with reference to the foregoing exemplary implementations. Although specific examples have been illustrated and described herein it is manifestly intended that the scope of the claimed subject matter be limited only by the following claims and equivalents thereof. It is to be understood, however, that other forms, details, and examples may be made without departing from the spirit and scope of the disclosure that is defined in the following claims.

[0012]支承体台架40被配置为结构框架,其可以包括导电材料。在一个示例中,支承体台架40包括非晶态金属合金。可以使用可用于将支承体台架40结构化地连接到马达35的转子的任何合适的机构来将支承体台架40连接到马达35。转子未在附图中示出,但是将容易地显见为包括马达35的驱动所连接的支承体台架40的旋转的运动部分。支承体台架40到马达35的连接可以是直接连接或者是利用中间组件的间接连接。在一个示例中,支承体托板45可以包括导电材料。在另一示例中,除了其它类型的材料之外,支承体托板45还可以包括玻璃或其它类型的透明材料,诸如石英、塑料、半导体。

[0015]参照图1和图2,图3是根据在此的示例的微LED像素显示系统10的示意图。微LED像素显示系统10包括多个传感器15、与多个传感器15相邻的显示屏幕20,其中显示屏幕20包括基底25和微LED控制装置30。多个传感器15可以包括红外虹膜识别传感器,并且可以位于电子装置12上的各种位置处。在各种示例中,传感器15可以位于显示屏幕20的前面或背面上。虽然各图将电子装置12描绘为膝上型计算机,但是在此的示例不仅仅局限于膝上型计算机。因此,依照在此描述的示例,可以利用具有显示器的其它类型的电子装置。在一个示例中,基底25可以包括显示屏幕20的基底,其中微LED控制装置30被构建在该基底25上并且包括该基底25。在其它示例中,基底25可以构成与微LED控制装置30分离的分立组件。
[0016]支承体构件31操作地将马达35连接到基底25。在一个示例中,支承体构件31可以包括焊接部。可以包括红外虹膜识别传感器的多个传感器15被设置为检测用户17的眼睛移动,在一个示例中,多个传感器15扫描用户17的眼睛,并且使用数学模式识别软件——其被本地存储在电子装置12上或者被使用固件远程地传递到电子装置12——以标识用户17的眼睛模式、形状、颜色等。一旦多个传感器15视觉地检测到用户17的眼睛,多个传感器15就基于检测到的用户17的眼睛移动向子像素驱动电路55传递诸如电信号的信号。在这方面,多个传感器15不仅检测用户17的眼睛的外观,而且还检测用户17的眼睛的移动。更特别地,当用户17以相关于电子装置12的各种角度移动他/她的头部时,多个传感器15检测用户17的眼睛的对应的移动。在一个示例中,如果传感器15被精细地调谐,则那么即使当用户不移动他/她的头部并且简单地使他们的眼睛移动时,传感器15也可以检测用户17的眼睛移动。因此,用户17根本不必移动他/她的头部,并且替代地可以在检测用户17的眼睛相对于电子装置12的位置和定位上的改变时使电子装置12关于静止的用户17移动。像这样,多个传感器15类似地试图检测用户17的眼睛。
[0017]在多个传感器15将信号传递到子像素驱动电路55之后,于是子像素驱动电路55指令马达35基于用户17的眼睛相关于显示屏幕20的位置来在规定方向上旋转。更具体地,子像素驱动电路55将诸如电信号的对应的信号发送到马达35以开始倾斜;即,在朝向所检测到的用户17的眼睛的位置的指定方向上旋转。例如,如果用户17位于电子装置12的显示屏幕20的左侧,则那么传感器15除了检测用户17的眼睛之外还将用户17的眼睛的相对位置检测为在电子装置12的左侧,并且向子像素驱动电路55发送对应的第一电信号,该子像素驱动电路55进而向马达35发送对应的第二电信号以开始朝向用户17的位置旋转;即,马达35开始向左旋转。图3图示了最初以笔直配置定位的微LED控制装置30的示例;即0°旋转,并且然后基于用户17——其被描绘为在电子装置12的左边——的对应的位置对应地向左旋转大约45°。
[0018]显示屏幕20包括像素区域60,该像素区域60包括像素50a、50b、50c的阵列65,其中像素50a、50b、50c的阵列65的每个像素区域60包括多个微LED控制装置30a、30b、30c。微LED控制装置30a、30b、30c分别包括关于从特定的装置30a、30b、30c发射的光的不同的色彩。在一个示例中,每个微LED控制装置30a、30b、30c包括分别对应于红色(R)、绿色(G)和蓝色(B)的不同的半透明的色彩过滤器32a、32b、32c,以使得当如在图4中描绘那样来自微LED 50的光被通过过滤器32a、32b、32c发射时,所发射的光变为对应的色彩;即红色、绿色或蓝色。微LED 50可以位于过滤器32a、32b、32c之下,或者如果过滤器32a、32b、32c被配置为类似胶囊的机构,则可以位于过滤器32a、32b、32c之内。参照图1至图3,图4图示了微LED控制装置30关于用户17的眼睛的移动或位置的旋转。微LED 50位于过滤器32a、32b、32c中以朝向用户17发射光,因为微LED控制装置30是朝向用户17定位的。在另一示例中,微LED 50可以包括不同的多色LED,以使得过滤器32a、32b、32c可以不必依照红色、绿色、蓝色配置而带有色彩。在另一示例中,微LED 50是多色的,并且过滤器32a、32b、32c也依照红色、绿色、蓝色配置来带有色彩。单色/多色LED 50与非色彩或色彩过滤器32a、32b、32c的各种组合分别控制从像素50a、50b、50c发射的整体色彩。
[0019]参照图1至图4,图5图示了多个微LED控制装置30a、30b、30c,其包括第一微LED控制装置30a、第二微LED控制装置30b和第三微LED控制装置30c,该多个微LED控制装置30a、30b、30c可以关于彼此独立地运动。例如,第一微LED控制装置30a可以旋转到第一角度θ1,第一微LED控制装置30a可以旋转到第二角度θ2,并且第一微LED控制装置30a可以旋转到第三角度θ3,以使得第一角度θ1、第二角度θ2和第三角度θ3可以彼此不同。在其它示例中,多个微LED控制装置30a、30b、30c彼此一致地运动;即,以使得第一角度θ1、第二角度θ2和第三角度θ3相同。
[0020]参照图1至图5,图6是图示如下的系统10a的示意图,该系统10a包括:多个红外虹膜识别传感器15;电路55,被设置为从多个红外虹膜识别传感器15接收第一组电信号;导电支承体框架,例如支承体台架40,其包括电路55;微LED像素50a、50b、50c,其附接在导电支承体框架40上;以及微电机35,其操作地连接到电路55和导电支承体框架40,其中微电机35在接收到基于从多个红外虹膜识别传感器15接收的第一组电信号的、来自电路55的第二组电信号时使导电支承体框架40和附接的微LED像素50a、50b、50c旋转。
[0021]微电机35被设置为使导电支承体框架40在关于二维旋转平面x-y的每个横向方向上旋转大约四十五度(45°)。多个红外虹膜识别传感器15被设置为检测计算机化装置的用户17的眼睛移动。第一组电信号包括与用户17的眼睛关于多个红外虹膜识别传感器15的方向位置相关的编码数据。第二组电信号包括使微电机35的旋转方向对应于用户17的眼睛的方向位置的编码数据。系统10可以包括电力单元75,其被设置为在多个红外虹膜识别传感器15未能检测到计算机化装置的用户17的眼睛时使微LED 50断电。系统10a包括系统10的所有特征,然而,与在图3中的多个成对的传感器15相比,在系统10a中仅提供一对红外虹膜识别传感器15。在各种示例中,该对红外虹膜识别传感器15可以位于屏幕20的前面或背面上。此外,在一个示例中,电力单元75也可以是系统10的一部分。
[0022]系统10a可以包括显示屏幕20,其中多个传感器15被设置为基于所检测到的用户17的眼睛移动来将第一组电信号传递到电路55,并且其中电路55基于用户17的眼睛关于显示屏幕20的位置来指令微电机35在规定的方向上旋转。
[0023]参照图1至图6,图7是图示如在方框101中示出那样包括感测与电显示屏幕20相邻的区域的环境光强度的方法100的流程图。接着,在方框103中,方法100包括使用被定位为相邻于电显示屏幕20的虹膜识别检测传感器15来检测用户17的瞳孔。方框105提供用于将电信号传递到嵌入在电显示屏幕20中的微LED像素显示器60,其中电信号包括与用户17的瞳孔关于电显示屏幕20的位置相对应的编码数据。方框107提供用于根据与用户17的眼睛的移动有关的电信号来控制微LED像素显示器60的旋转,并且方框109示出方法100包括以多个角度旋转微LED像素显示器60以调整针对电显示屏幕20的视场。方法包括使微LED像素显示器60在关于二维旋转平面x-y的每个横向方向上旋转大约四十五度(45°)。可以在大约一秒内出现微LED像素显示器60的完整的90°的旋转角度。例如,参照图4,微LED控制装置30可以在大约一秒内从在图4的左侧上示出的倾斜位置转变到在图4的右侧上示出的倾斜位置,其中在图4中可以出现从左侧图像到右侧图像的完整的90°的旋转角度。
[0024]通过旋转,微LED控制装置30能够使来自LED 50的光朝向用户17的方向发射。在这方面,如果用户位于电子装置12一侧,则那么传感器15试图搜索用户17的眼睛。一旦传感器15作出与用户17的眼睛的视觉接触,于是就出现电信号的对应传输;即从传感器15到子像素驱动电路55,并且然后从子像素驱动电路55到马达35,引起马达35和对应地连接的支承体台架40、支承体托板45以及微LED50的朝向用户17的旋转。
[0025]在一个示例中,因为微LED 50仅在一个方向上成角度;即朝向用户17,当以未与用户17对准的角度观看时,显示屏幕20将呈现为暗或者另外具有较小的视觉敏度。因此,如果用户17位于挨着另外一人并且用户17向左或向右移动他/她的头部,则那么传感器15通过检测用户17的眼睛的移动和位置来检测该移动,并且因此使微LED控制装置30旋转。位于挨着用户17的相邻的人在试图观看显示屏幕20时将看到暗的屏幕,因为微LED 50并未在相邻的人的方向上进行发射。在另一示例中,当传感器15未能检测到用户17的眼睛时,在预定的时间段之后,电力单元75可以使微LED 50断电。这造成显示屏幕20变暗,并且因此在相对于显示屏幕20的任何角度下显示屏幕20上的数据或图像都是不可观看的。
[0026]参照图1到图7,图8图示控制系统120的方框图,控制系统120通过如下来提供用于自动屏幕观看角度调整解决方案:通过红外虹膜识别和标识传感器15以及对应的虹膜识别软件模块123来检测并且识别在用户17的眼睛瞳孔上的收缩响应和扩张响应的差异程度,以便基于用户的眼睛的方向移动和位置而具有对显示屏幕20的自动的并且实时的微LED目光接触控制。如由微LED控制装置30所使能的那样,微引擎控件122可以把由接收传感器15所提供的数据的传感器模块125所编译的数据与存储在存储器124中的针对给定的用户17的自动生物标识信息进行组合,以提供针对电子装置12的安全访问以及在屏幕20上显示的内容的用户验证。因此,当用户17从不同的方向读取和操作屏幕20时,微引擎控件122提供对显示屏幕20的增强的和安全的观看。例如,用户17可能正在阅读一本书或一份文件并且不断地在显示屏幕20和该份文件之间来回扫视。微引擎控件122评估用户17何时实际地注视屏幕20,并且对应地调整来自微LED 50的光的方向和发射。这允许像素50a、50b、50c仅在对应的角度下——在该角度上定位了用户17的眼睛/用户17的眼睛与屏幕20对准——可观看。为了增强的信息保护和安全目的,可以对虹膜识别模块123编程以通过包括密码输入和/或面部识别或其它生物识别处理的安全认证处理来仅识别先前已经利用系统10、10a登录的特定用户17的眼睛。
[0027]虹膜识别模块123和传感器模块125可以包括硬件元素和软件元素以使得能够进行所检测到的用户17的眼睛与存储在存储器124中的用户17的眼睛的图像的适当的模式匹配。因此,在此的各种示例可以包括硬件元素和软件元素这两者。以软件实现的示例包括但是不限制于固件、驻留软件、微代码等。其它示例可以包括被配置为包括预先配置的指令集的计算机程序产品,当执行该指令集时,可以造成如与上面描述的方法结合地说明的动作。在示例中,预先配置的指令集可以被存储在包含软件代码的有形的非暂态计算机可读介质或程序存储装置上。
[0028]已经参照前述的示例性实现示出并且描述了本公开。虽然在此已经说明和描述了具体的示例,但是明显意图的是要求保护的主题的范围仅由随后的权利要求及其等同物限制。然而,要理解可以在不脱离在随后的权利要求中限定的本公开的精神和范围的情况下作出其它的形式、细节和示例。
