Abstract

The utility model is a screen system capable of automatic regulating brightness according to scene claim, which belongs to the photoelectric technical field. A photoelectric inductor, a signal processing circuit and an A/D converter are added into the screen system, the photoelectric inductor connects with the signal processing circuit, the signal processing circuit connects with the A/D converter, and the A/d convert connects with the CUP. So the photoelectric inductor receives the outside light of the screen to produce a light intensity electrical signal, after the comparison of strength, the photoelectric inductor automatically adjusts the display scheme which is stored with the corresponding brightness according to the light intensity to achieve the scene claim and the function of adjusting the screen brightness and colour.

Description

Can require to regulate automatically the screen system of brightness according to scene

Technical field:

The utility model belongs to field of photoelectric technology, a kind of screen system that can require to regulate automatically brightness according to scene.

Technical background:

Modern social development is rapid, and mobile phone just is able to popularize rapidly in recent years.The mobile phone technique development is rapid, and market competition is fierce day by day, and the various performances that improve perfect mobile phone become the focus that each mobile phone producer endeavours to study.The utility model relates to the mobile phone screen brightness problem, and modern most of mobile phone is than all there being Presentation Function preferably under the dark situation, but under high light especially sunlight often because of reflective etc. former thereby can not see the word of screen clearly, influence is normally used.

Two kinds of improvement technology are generally arranged now, and a kind of is plated film on screen, and reflection ray is filtered, and another kind then is to improve brilliant screen at night, increases backlight, uses strong brightness liquid crystal etc. instead, promptly strengthens showing by increasing screen intensity.But so just can cause a problem, if at night, the too bright meeting of screen is dazzling, needs backlight to be turned off or turned down brightness, and screen is dimmed; Daytime in the sun, and is or too dark again when using under high light evening, needs backlight opened light is lightened.Mobile phone screen is regulated back and forth, certainly will bring a lot of troubles to the user.In addition, palm PC, similar products such as MP4 also all have same problem, and this is also contained in the utility model scope of application.

Summary of the invention:

Brightness under the different light intensity background shows problem at screen, and the inventor has designed a photoelectricity regulating circuit, regulates screen intensity automatically according to light intensity.In the screen system, except that having LCD, screen backlight circuit, CPU processor, outside the storer, increase photoelectric sensor, signal processing circuit, A/D converter, photoelectric sensor links to each other with signal processing circuit, and signal processing circuit links to each other with A/D converter, and A/D converter links to each other with CPU.Photoelectric sensor receives screen ambient light line like this, produces a light intensity electric signal, through strength ratio after, call the bright scheme of storing under the corresponding bright automatically according to light intensity, so just reached according to the scene demand, regulate the function of screen intensity, color automatically.

Description of drawings:

Fig. 1 is a synoptic diagram of the present utility model

Fig. 2 is a circuit module figure of the present utility model

Please refer to Fig. 1 synoptic diagram of the present utility model, the 1st, obedient hole, the 2nd, photoelectric area sensor, it can respond to the light intensity in the screen external world, produces the electric signal of light intensity,

Embodiment:

In Fig. 2, LCD in the display system, display driver circuit, screen backlight circuit, CPU processor, the connected mode inconvenience that storer is original, the photoelectric sensor of Zeng Jiaing in addition, signal processing circuit, its connected mode of A/D converter is: photoelectric sensor links to each other with signal processing circuit, signal processing circuit links to each other with A/D converter, and A/D converter links to each other with CPU.

At first be the formation of displaying scheme.The user can be divided into some grades with environmental light intensity of living in mobile phone, as following three grades of: night, daytime, sunlight, and can be according to hobby to the display mode such as the brightness of each grade, colors etc. are provided with, storage and form user's displaying scheme when it reaches individual's relatively optimum efficiency.

When in this functional mode following time, photovoltaic sensing element receives screen ambient light line, and the electric signal of generation is after processing of circuit, produce digital signal through the A/D conversion, input processor, through strength ratio after, call the displaying scheme under the respective strengths acquiescence of storing in the storer or that the user is provided with.Like this when you from range of light intensity following time, go under another range of light intensity, then call the brightness display mode under another light intensity.Color also can be according to the hobby setting of oneself, and the individual character that increases mobile phone shows.When settings such as brightness, color feel not too suitable, can revise the setting under this light intensity and preserve forming new display mode.

Claims

1, a kind of screen system that can require to regulate automatically brightness according to scene, it has LCD, display driver circuit, screen backlight circuit, the CPU processor, storer, its feature is being: also have photoelectric sensor, signal processing circuit, A/D converter, photoelectric sensor links to each other with signal processing circuit, and signal processing circuit links to each other with A/D converter, and A/D converter links to each other with CPU.
