Abstract： |
This system consists of the brightness collecting unit (BC), the data storing unit, the comparing unit (CP) and the controlling unit (CT). BC collects at least the environment light brightness (ELB) and the displayer irradiance brightness (DIB). The output of CP at least includes the comparing results of ELB and DIB. At least two outputs of CP are simultaneously sent to inputs of CT. This invention tests displayer irradiance intensity and the environment light intensity. Except BC, others may realize via software without adding peripheral hardware. It ensures the driving current of each pixel to consult simultaneously at least two data. This prevents the display effect from influencing due to decay of ELB and the irradiance material. It enables the displayer to possess a normal irradiance effect under different environment or after different using time. This invention suits certain especial areas where the performance of displayer brightness and contrast are important. |
