Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a display device and the adjustment method therefor, specially a liquid crystal display (LCD) device and the display mode adjustment method therefor. 
       BACKGROUND OF THE INVENTION 
       [0002]    It is frequently required to adjust the display parameters of the display device, e.g. liquid crystal display, based the using conditions. These display parameters are often too professional for the users. Accordingly the users do not know how to set up these parameters, and feel troubled. 
         [0003]      FIG. 1  is the schematic diagram showing the conventional adjustment method for the display performance of the LCD. Please refer to  FIG. 1 . Firstly, the user  10  utilizes the key pad  12 , which may be located in the lower portion of the television (TV) or on a remote controller. The display function key on the key pad  12  is pressed by user  10 . Then, the display parameters  14  will appear on the screen to partially or completely cover the original picture displayed on the screen. For instance, the texts of the display parameters, such as brightness, contrast ratio, color temperature, horizontal position, vertical position, clock, phrase, etc., will appear on the screen. At that moment, user  10  can utilize the Up and Down buttons on the key pad  12  to move the cursor to some specific parameter, and press the Enter button to adjust that specific parameter. The bar chart or the default number will appear on the screen. The user  10  can utilize the numerical buttons on key pad  12  to enter a new set number, or press the Right or Left buttons on key pad  12  to adjust the relative magnitude of that parameter on the bar chart, and finally press the Enter button to complete the parameter setting. As to the setting of the other parameters, the same method can be followed to finish the setting of each parameter one by one and finally to complete the display function settings of the display device  16 . 
         [0004]    The above mentioned setting method is quite inconvenient. Furthermore, when the using condition is changed, the same tedious setting procedures have to be run again. For example, when reading the emails right after watching DVD, the user has to set up the display parameters again; otherwise the screen is too bright and harsh for the eyes of the user. From the above, it can be seen that it is certainly necessary to improve the setting method for the display parameters. Moreover, it can be worse that these display parameters are too professional for a lot of users, and the users do not know what the brightness, contrast ratio, color temperature are, and are troubled by completely no idea about the display parameter setting. 
         [0005]    From the above, the conventional adjustment method of the display parameters for the display device anxiously needs to be improved. The development team of the present invention paid a lot of efforts in the research and analysis in this field, and finally developed a novel and effective adjustment method for the display devices. After several trials and improvements, the present invention can solve the above-mentioned problems by introducing the novel technical logic and the friendly operation modes, and can eventually benefit all the users. The present invention is described below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0029]    The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for the purposes of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed. 
       First Embodiment 
       [0030]    Please refer to  FIG. 2 , which is the schematic diagram showing the adjustment method of the display performance according to the first embodiment of the present invention. W hen the display device is closed in Step  20 , the button can be pressed once in Step  21   a  so as to turn on the display device in Step  22 . When the original button is pressed once again in Step  21   b,  the icon and/or illustration texts for the display mode will be shown on the screen in Step  24 . For example, the text, “Text Mode”, is shown on the screen, and the picture of the screen is displayed according to the display parameters set in the “Text Mode”. When the original button is pressed once again in Step  21   c,  the icon and/or illustration texts of the next display mode will be shown on the screen in Step  26 . For instance, the text, “Movie Mode”, is shown on the screen. Similarly, the picture on the screen is displayed according to the display parameters set in the “Movie Mode”. In Step  25 , when the original button is not pressed during the waiting time (can be set to 2-5 seconds, e.g. 3 seconds, as considering the user&#39;s behaviors), the display device is designed to choose that display mode and to turn off the display of the icon and/or illustration text of that display mode in Step  28 . When the original button is pressed once again during the waiting time, e.g. 3 seconds, the next display mode will be shown on the screen. When the last display mode is shown on the screen, and the original button is pressed again during the waiting time, e.g. 3 seconds, then the first display mode will be shown on the screen circulatively. 
         [0031]    Whenever the display device is turned on, and the original button is continuously pressed and held for a holding time in Step  23  (can be set to 2-5 seconds, e.g. 3 seconds, as considering the user&#39;s behaviors), the display device can be turned off. 
         [0032]    In this embodiment, the user can use a single button to turn on and to turn off the display device and to choose the display mode for the display device. The operations are quite easy for the users. The display mode shown on the screen is friendly and understandable, such as Text, Movie, etc. No display parameter with profound professional term, e.g. brightness, contrast ratio, color temperature, etc. needs to be set. Therefore, the easy and convenient adjustment method with the technical novelty is introduced in this embodiment, can solve the problem of the complicated display parameter settings in the current techniques, and can provide the great advantages for all the users. 
         [0033]    Although only a single button is used in this embodiment, the display device can be designed to contain two buttons as well based on the spirit of present invention. For example, one is used as a switching button to turn on and off the display device, and the other one is used as an operation button to choose the desired display mode. This design is still within the spirit and protection scope of the present invention. 
       Second Embodiment 
       [0034]    Please refer to  FIG. 3 , which is the schematic diagram showing the display mode of the adjustment method of display performance according to the second embodiment of the present invention. In this embodiment, there are six display modes are cited, i.e. “General Mode”  30 , “Text Mode”  32 , “Game Mode”  34 , “Movie Mode”  36 , “X-Contrast Mode”  38 , and “X-Fine-Tuning Mode”  39 . Similarly as the first embodiment, when the display device is on, the user can press the original button once, and then the first display mode, i.e. “General Mode”  30 , will be shown in and covering the real-time picture on the screen. When the user presses the original button once again during the preset waiting time, e.g. 3 seconds, the next display mode, i.e. “Text Mode”  32 , will be shown on the screen. By using the same method, when the user continuously presses the original button within the preset waiting time, e.g. 3 seconds, in each time for several times, then the following display modes, “Movie Mode”  36 , “X-Contrast Mode”  38 , “X-Fine-Tuning Mode”  39 , and back to the first mode, “General Mode”  30 , will be sequentially and circulatively displayed on the screen. Whenever the user does not press the original button during the preset waiting time, e.g. 3 seconds, the display device is designed to choose the display mode at that time, to terminate the display of the icon and/or illustration text on the screen, and to display only the real-time picture on the screen. 
         [0035]    In this embodiment, six display modes are cited. The user can quickly and conveniently select the desired display mode according to the usage situation, and does not need to do the complicated settings for the profound display parameters. This embodiment provides the adjustment method for the display device with the easy and convenient operations suitably for the general users. If the user is an expert and is professional in the display performance setting, then the display mode, “X-Fining-Tuning Mode”  39 , is available to do the customized setting for the display parameters according to the personal preferences. Therefore, the present invention can provide both the operational convenience and the professionalism for the adjustment of the display performance of the display device.
