Abstract

The invention provides a color temperature calibration method and a mobile terminal, and the method comprises the steps: detecting whether color decay happens to a to-be-calibrated display screen or not; obtaining the current RGBW data of the display screen when the color decay is detected to happen to the to-be-calibrated display screen; adjusting the RGB components according to the current RGBWdata and a predetermined color temperature, wherein the RGB components are the basis that the display screen displays a white picture. Therefore, the calibration operation of the color temperature isnot carried out at the display screen according to the scheme of the invention, but is carried out at the mobile terminal side, so MTP does not need to be carried out in the whole calibration processfor many times, thereby saving the subsequent maintenance cost, and simplifying the complex operation.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a color temperature calibration method and a mobile terminal. Background technique

[0002] At present, the common white point calibration on the display screen of the mobile terminal is to enter the required color temperature information into the LCD module by multiple programming (MTP) on the LCD screen side, and then the color temperature calibration is completed.

[0003] However, the traditional color temperature calibration work is to calibrate from the LCD display side. Because the display brightness of the LCD module will have color fading, that is, the color will drift with the time the screen is turned on, so the display screen is at MTP. , due to factors such as color fading, the color temperature will change greatly in the later stage of calibration, and MTP correction is required on the display screen, and the process of MTP itself takes a lot of time, so doin...
