Abstract
The utility model relates to a display capable of automatically regulating self brightness along with variation of environment brightness, comprising a display panel and a main board circuit. The display is characterized in that a brightness probe hole is arranged on the surface of the display panel, a sensor used for probing current variation of the environment brightness is arranged in the hole, and the sensor is sequentially connected with a register of the main board circuit, a numeral code conversion chip and a microprocessor. The utility model adds a light sense device on the basis of the prior display, and can probe the current environment brightness, and thereby, the function of automatically regulating the current brightness is achieved and the aim to protect vision of a watching person is achieved.
Description
Technical field
The utility model belongs to display, relates in particular to a kind ofly can change the display regulate self brightness automatically with ambient brightness.
Background technology
Brightness behind the display starting of Xiao Shouing in the market is to adjust in advance according to people's general custom producer, preset the pattern (as: film/dynamic/text/recreation etc.) of several frequent uses simultaneously, but every kind of pattern needs artificial manual switch.But along with ambient brightness changes, make the display effect of display can not reach best, influence people's eyesight simultaneously.Also do not have at present and can change and regulate the display of self brightness automatically along with ambient brightness.People demand urgently requiring manufacturer that the display of its production is also constantly weeded out the old and bring forth the new aspect the hommization.
The utility model content
The utility model is in order to overcome deficiency of the prior art; provide a kind of and can change the display regulate self brightness automatically with ambient brightness; do not need the people manually to regulate, can realize regulating automatically self brightness, to reach the intelligent display of protection beholder eyesight purpose.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind ofly can change the display regulate self brightness automatically with ambient brightness, comprise display pannel and motherboard circuit, it is characterized in that: described display pannel surface is provided with the brightness exploration hole, the hole is built-in with and is used for surveying the sensor that current environment brightness changes, and described sensor is connected successively with the register of motherboard circuit, digital conversion chip, microprocessor.
The beneficial effects of the utility model: on existing display basis, increase the light sensation device, can survey current environment brightness, thereby reach the function of the current brightness of automatic adjusting, to reach the purpose of protection beholder eyesight.

Fig. 1 is the utility model circuit side connector block diagram.
Embodiment
Below in conjunction with preferred embodiment, details are as follows to embodiment that foundation the utility model provides.See accompanying drawing for details, a kind ofly can change the display regulate self brightness automatically with ambient brightness, comprise display pannel and motherboard circuit, described display pannel surface is provided with the brightness exploration hole, the hole is built-in with and is used for surveying the sensor that current environment brightness changes, and described sensor is connected successively with the register of motherboard circuit, digital conversion chip, microprocessor.Element effect: photosensitive sensor: luminance signal seizure/collection; Register: signal storage; Digital conversion: conversion of signals becomes digital signal; Microprocessor: by processor/output anticipation corresponding brightness control signal; BLU control circuit: change the brilliance control parameter.
Principle of work: the built-in sensors at panel top collects the monochrome information of current environment, with this information number conversion chip by changing, be transferred in the microprocessor (MICOM) after being transformed into electric signal, MICOM I/O mouth voltage changes thereupon when surrounding environment change, MICOM passes through the numerical value that the initial program of depositing reduces Lamp electric current and PWM Dimming automatically and (pre-determines constant brightness when interval, best use brightness, and deposit initial program in), thus the brightness of back light unit LAMP changed.Reach the purpose of automatic variation brightness.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
