When there is a chemical formula, please disclose the chemical formula of the most invented features. · Description of the invention: [Technical field of the invention] The screen display contrast of the tablet computer is automatically adjusted 4 ', ,, set, especially private An adjustment mechanism is arranged between the light sensing and the brightness control circuit of the screen on the surface of the screen, so that the ambient light (operation = light) when the tablet is used is changed. When strong or weak, through the sensing effect of the light sensing component, the brightness control circuit of the 2 screen automatically generates an action to automatically adjust the brightness of the Qin, for automatically and operating ambient light to maintain an appropriate contrast. [Prior Art] △ According to the 'currently available tablet PCs, most of them have screen brightness adjustment function'1 In order to adjust the brightness of the screen, most of the commercially available tablets have buttons. Adjust the brightness of the screen conveniently and quickly. Although most of the tablets are designed to quickly adjust the brightness of the screen, the quick button 'allows the user to easily and quickly adjust the brightness of the screen', but the user needs to check the tablet when using the computer. In case of ambient light (operating ambient light), press the button to adjust the brightness of the screen to make the brightness of the screen meet the user's needs. Therefore, it is inconvenient in operation. Therefore, it should be improved in terms of ease of operation. As shown in FIG. 1, a schematic diagram of a tablet computer is known. In the illustration, the tablet computer 1 includes a conventional LCD panel display 11 and a fixed button 12 is provided on the casing of the tablet computer 10. The user can adjust the LCd panel display 11 by pressing the button 12. Screen brightness, these 7C are well known in the art. 201225060 ‘How to design an auto-tunable 3 for this demand; however, no one has seen a design that meets the above requirements in the current tablet market. In view of the above, the present invention mainly provides a flat-panel computer display contrast automatic miscellaneous device to overcome the above-mentioned shortcomings, although J=adjustment has been a conventional technique, but different application fields exist in terms of overall structure and function appeal. A large technical difference. [Invention] The main purpose of Qiaoming is to provide a screen computer with no contrast contrast automatic adjustment system for the lack of the above-mentioned technology, as installed on the screen of the screen. Selecting the U position system = even 2 in the light sensing device and the bright screen mechanism of the glory to make the brightness control circuit of the 幕 screen automatically play the role of the contrast Ft redundancy 'for the automatic and operating environment light is maintained - the 2 operating ring is strong when the brightness of the screen is relative to the image, and can achieve the thunder and the device to see the consumption of the screen and its carrying Usage readability: It is beneficial to reduce the battery of the tablet.

For the automatic ambient light to become strong, the brightness of the screen 21 is the phase; the cow is listed as $'. When the brightness of the honor screen 21 is operated, the phase is displayed, and the image displayed by the screen 21 is displayed. Convenience i is beneficial to reduce the battery consumption of the tablet computer and its carrying and use. Referring to FIG. 4-5, it is a schematic diagram of the brightness control structure of the automatic adjustment system device and the light sense control of the screen display of the tablet computer of the present invention. . As shown in FIG. 4, the brightness control circuit 24 of the screen 21 is further disposed inside the tablet body 20. The brightness control circuit 24 includes a basic input/output system (BIOS) 40 and a programmable program. The memory 42 forms an electrical connection, such as the basic input/output system (BI〇S) 40 using the system management bus (SMBUS) 41 as an electrical connection, but is not limited; wherein the light sensing component 30 is associated with the basic The Basic Input/Output System (BIOS) 40 is electrically connected, such as the System Management Bus 'SMBUS 41 link'. By using the application software, the basic input/output system can be executed (BI〇S). 4〇 setting to set the light sensing value and divide the light sensing value into multiple orders in 201225060; in this embodiment, 'from 〇 to 7 is divided into 〇, 1 and 2, 3rd order, 4th order, 5th order, 6th order, 7th order, 8 orders, and the value is from small to large to indicate that the brightness is from darkest to brightest, but its order is not limited, as shown in Figure 5. 'Set the light sensing value to 3 steps, and the second order to indicate the darkest brightness' The third order indicates that the brightness is medium, the seventh order indicates that the brightness is the brightest, and the third or seventh order of the light sensing value is selected in an automatic control manner. The three orders described above cannot meet the user's needs, and The above-mentioned application software is used to perform the order adjustment of the respective brightnesses, such as increasing the number of orders to achieve the user's operation requirements. Moreover, the operation mode setting of the Basic Input/Output System (BIOS) 40, such as manual or automatic, is used as an adjustment of the light sensing value by using a software program; for example, When set to manual mode, it is adjusted by manual operation. When it is set to automatic mode, in addition to automatic operation adjustment, manual (fine adjustment) adjustment can be performed to achieve manual and automatic parallel function. In addition, the Basic Input/Output System (BIOS) 40 also controls the brightness of the screen 21 by Pulse Width Modulation 'PWM' to improve the efficiency of the power application and reduce the use. Space and system costs. Further, in the present embodiment, the setting of the function keys 22 is performed in the state of φ windows, and the setting of the function keys 22 can be changed a plurality of times and the previous settings are replaced by the subsequent settings. According to the above, the screen display automatic adjustment system device of the tablet of the present invention, the brightness control of the screen 12 is set by the basic input/output system (BIOS) 40 to set the light sensing value (such as 〇 to 7th order) and operating modes (such as manual, automatic) to provide an extremely easy and convenient setting operation; and function key 22 can be customized according to the requirements of the user to meet the competition of the market. Sex. Compared with the prior art tablet computer, the screen display contrast automatic adjustment system device of the tablet has the following advantages: 1. The brightness of the screen can be automatically adjusted: the light sensing component, the screen brightness 201225060 degree control circuit and corresponding The components are formed and achieved. 2. The light sensing value of the light sensing device is easy to set up. · The light sensing value is set by the basic wheel in/out system (BIOS), which is easy to operate and can be freely set to "the size of the light sensing value." & 3, with power saving effect · By automatically adjusting the brightness of the screen can reduce the battery consumption of the computer. _ Xi 4, with excellent ease of use: in line with the user's simple operation 5. Customizable function key settings: function keys can be set multiple times ~ function and easy to set up.
