Embodiment
Below in conjunction with drawings and the specific embodiments the present invention program is described in further detail.
Implementation of the present invention mainly is: gather the light intensity of display device exterior, and determine corresponding display parameter according to the data relevant with light intensity of being gathered, show according to these display parameter then.
When stating scheme in realization, the present invention sets up illuminant module and pretreatment module on display device, and its circuit structure as shown in Figure 1.Display device is measured the light intensity of external environment by illuminant module, and the light intensity related data that records is sent to pretreatment module; Pretreatment module is determined corresponding display parameter according to current light intensity, and gives main control module in the display device with determined display parameter value real-time Transmission; Main control module is according to the output effect of the display parameter real-time regulated display unit that receives.
Wherein, illuminant module specifically can be made up of sensor devices and amplifier, and sensor devices changes resistance according to light intensity and changes, thereby causes circuit voltage to change, again by amplifier with voltage amplification, and the voltage transmission after will amplifying is to pretreatment module.This sensor devices can be photoresistance, is example with photoresistance as sensor devices, the resistance of photoresistance can change with the power of extraneous light, therefore the voltage that amplifier inserted also just changes thereupon, voltage after amplifier will change amplifies, and the voltage after will amplifying is transported to pretreatment module.This illuminant module specifically can be set to circuit structure shown in Figure 2.What among Fig. 2 photoresistance R5 and amplifier are adopted is highly sensitive connection in bridge, V
rBe reference voltage, V
mSampled voltage after be amplifying, this connected mode can convert photoresistance to output voltage V because of the small conversion of extraneous light
mBigger variation.Its enlargement factor is
Wherein, R is the initial reference resistance of photoresistance.
Pretreatment module specifically can comprise analog-to-digital conversion module and micro treatment module.By analog-to-digital conversion module the voltage that illuminant module transmission comes is carried out analog to digital conversion, and the data after will changing send micro treatment module to, the data after this conversion are called light intensity data.Micro treatment module is then determined display parameter according to the light intensity data received, and gives main control module in the display device with determined display parameter real-time Transmission.Wherein, micro treatment module determines that display parameter specifically can be: set in advance the light intensity data that receives and the corresponding relation of display parameter according to actual conditions, determine the pairing display parameter of the current light intensity data of receiving according to this corresponding relation then.Certainly, if comprised parameters such as brightness, contrast, colourity and acutance in the display parameter simultaneously, then when being provided with, brightness and contrast's amplitude of variation can be provided with broad, be provided with the amplitude of variation of colourity and acutance narrower.
Wherein, pretreatment module specifically can also be given main control module with the display parameter real-time Transmission by data bus.Therefore, the micro treatment module in the pretreatment module also should be able to be provided with different data buss according to different master cpus, such as, serial bus, 8 bit parallel buses, I2C bus, spi bus etc. can be set as required.Such pretreatment module can realize that the bus matching principle of MCU wherein as shown in Figure 3 by analog to digital converter and pre-service microprocessor (MCU).
Main control module in the display device is after receiving these display parameter, promptly according to the output effect of this display parameter real-time regulated display unit.This main control module can be a master cpu.
In addition, for making measured light intensity more reasonable, a plurality of illuminant modules can also be set, these illuminant modules can be arranged on the diverse location of display device exterior.Like this, pretreatment module will be received the magnitude of voltage that a plurality of illuminant modules send, after these magnitudes of voltage are carried out analog to digital conversion respectively, the light intensity data that is converted to is handled by micro treatment module, obtain a comprehensive light intensity index, and then determine corresponding display parameter according to this light intensity index by micro treatment module.Wherein, micro treatment module obtains comprehensive light intensity index according to the light intensity data that is converted to, can be to obtain by these light intensity datas being carried out the function processing, such as, can average to light intensity data, can certainly carry out other function processing light intensity data.
Obviously, at any time, observer can also be adjusted display parameter according to existing regulative mode.Can also be provided with main control module, make experienced observer to set the pairing display parameter of each light intensity data in the display device according to actual conditions.If each display parameter setting is order clocklike such as increase progressively, successively decrease, then can also the display parameter initial value be set by observer, pretreatment module can be determined all display parameter according to this initial value.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
