Description
Technical field
The present invention relates to a kind of display brightness automatic regulating apparatus, specifically a kind of device and method of adjustment thereof of adjusting display brightness according to ambient brightness automatically.
Background technology
When the user used display, the brightness of display had great influence to user's euphorosia degree.When initial, the brightness and contrast of display is set to fixed numeric values, but surrounding environment is constantly to change, when daytime, night, bad weather are arranged, and in different environment, for example in parlor and bedroom or the like, the brightness of surrounding environment all is vicissitudinous.
Because the numerical value of display brightness and contrast fixedly installs at present, brightness is not gathered, analyzes, is detected and judges to surrounding environment, thereby also can not come dynamic adjustments display picture output brightness, but adopt unified OSD manual mode to regulate brightness without exception according to ambient brightness.The shortcoming of this display brightness regulative mode is:
1) bright excessively when surrounding environment brightness, during the too dark brightness of display, brightness can not in time change, and it is uncomfortable that the user feels;
2) when the surrounding environment too dark brightness, the brightness of display is crossed when bright, and brightness can not in time change, the user feels uncomfortable.
Summary of the invention
In order to overcome the problem that existing display brightness regulative mode exists, the purpose of this invention is to provide a kind of device and the method for adjustment thereof that can adjust display brightness according to ambient brightness automatically.The present invention is according to the variation of surrounding environment brightness, and after the identification of photoinduction device, chip is regulated the background light source of display automatically, thereby changes display brightness, to avoid display picture to cross dark for surrounding environment or to cross when bright user's use feeling to uncomfortable.
The objective of the invention is to be achieved through the following technical solutions:
A kind of device of adjusting display brightness according to ambient brightness automatically, it is characterized in that: it comprises outside brightness acquisition testing module, inter-process module and brightness adjusting module, outside brightness acquisition testing module collection also detects outside luminance signal, and will flow to the inter-process module after the outside luminance signal process photoelectricity analog to digital conversion; The inter-process module is handled the luminance signal that outside brightness acquisition testing module transports, through with the brightness value of setting relatively after, calculate and be provided with the output luminance parameter; The brightness adjusting module receives the output luminance parameter that the inter-process module is provided with, and the picture output brightness of display is adjusted.
Among the present invention, outside brightness acquisition testing module flows to the inter-process module by bus with outside luminance input signal.
Be provided with central processing element in the inter-process module, with the brightness value comparative result of setting be that the brightness value that luminance input signal surpasses setting was bright; The brightness value that luminance input signal is lower than setting was dark.
The brightness adjusting module changes the brightness of backlight by the PWM mode, and changes the picture output brightness of display.
A kind ofly adjust the method for adjustment of the device of display brightness automatically, it is characterized in that it may further comprise the steps according to ambient brightness:
1) adjusting automatically under the pattern of display brightness, outside brightness acquisition testing module is collected the brightness of display surrounding environment and will be flowed to the inter-process module after the outside luminance signal process photoelectricity analog to digital conversion;
2) the inter-process module compares luminance signal and the range of set value of receiving, if the luminance signal that collects is lower than setting value lower limit, then is judged to be outside too dark brightness; If it is bright excessively that the luminance signal that collects, then is judged to be outside brightness than limit for height on the setting value; Be lower than the setting value upper limit if the luminance signal that collects is higher than the setting value lower limit, then be judged to be appropriate brightness;
Calculate and the output luminance parameter that is fit to environment is set according to above-mentioned result of determination, and will export luminance parameter and flow to the brightness adjusting module;
If be judged to be outside too dark brightness, then reduce output brightness of display; If it is bright excessively to be judged to be outside brightness, then improve output brightness of display; If be judged to be appropriate brightness, then by former brightness output.
3) the brightness adjusting module receives the output luminance parameter of inter-process module, and the picture output brightness of display is adjusted automatically.
The present invention is when surrounding environment is brighter, and the brightness of display will improve automatically; When surrounding environment is darker, the brightness of display will reduce automatically.Among the present invention, the user can select Dazzling Care opening in custom menu, and then display can change the output brightness of display automatically according to brightness on every side, makes the user obtain best visual effect.
