Problems solved by technology

[0005] However, the maximum charging demand is not always required when the LCD panel of the mobile phone is displayed
When the charging demand of the LCD panel of the mobile phone is small, the driving capability of the buffer amplifier at the source output end of the driver chip does not actually need to be very large at this time, but the driving capability of the buffer amplifier is fixed at this stage, and the power consumption of the buffer amplifier itself is also very high. Large, so it will cause waste of power consumption of the driver chip itself

Abstract

The invention provides a mobile phone driving system and method. The system comprises a video signal standard receiving port module, a content adaptive backlight module connected with the video signal standard receiving port module, a picture gray scale detection module connected with the video signal standard receiving port module, a buffer amplifier dynamic regulation module connected with the content adaptive backlight module and a digital-to-analogue conversion module, the digital-to-analogue conversion module connected with the content adaptive backlight module, and a source output module connected with the digital-to-analogue conversion module. A buffer amplifier can be dynamically regulated to work, so as to reduce the power consumption of a driving chip.

Description

technical field [0001] The invention belongs to the technical field of display drive control, and in particular relates to a mobile phone drive system and method. Background technique [0002] Such as figure 1 As shown, the LCD (Liquid Crystal Display) panel of the mobile phone is charged and discharged through the source and output terminals of the mobile phone driver chip. Brightens the LCD panel of the phone. [0003] Such as figure 2 As shown, at present, mobile phone driver chip design manufacturers will add a buffer amplifier to each source line in the digital-to-analog conversion module in the driver chip when designing the driver chip, so that the source and output terminals of the driver chip have certain driving capabilities. [0004] When the mobile phone driver chip drives the LCD panel of the mobile phone to display normally, the driving capability of the buffer amplifier in the digital-to-analog conversion module in the driver chip is fixed. Of course, the...
