Problems solved by technology

[0002] The signal received by the driver of the display device may become faster (or slower) due to the influence of temperature changes on the oscillator, which may cause abnormalities in the driver's reading and writing of display data
The existing practice is to adopt temperature compensation, but there will be error accumulation, which will lead to abnormal situations in the read and write display data of the drive

Embodiment Construction

[0026] The present invention provides a dynamic frequency compensation method and a dynamic frequency compensation system using the dynamic frequency compensation method. The dynamic frequency compensation system is arranged in the display device. The display device is, for example, a mobile phone, but not limited thereto. The dynamic frequency compensation system receives different signals and maintains the speed difference between the signals according to the preset frequency difference. The dynamic frequency compensation method can avoid the situation that the frequency difference between the received signals is too large and the abnormal reading and writing data occurs.

[0027] figure 1 This is a flow chart of an embodiment of the dynamic frequency compensation method of the present invention. like figure 1 As shown, the dynamic frequency compensation method includes steps S10-S50. In step S10, a frequency difference between the display signal and the clock signal is...

Abstract

The invention provides a method for dynamic frequency compensation and a dynamic frequency compensation system. The method includes the following steps: (A) presetting a frequency difference associated with a display signal and a clock signal; (B) receiving a current display signal from a controller by a driver, wherein the current display signal has a first frequency, and receiving a current clock signal inside the driver, wherein the current clock signal has a second frequency; (C) comparing the first frequency with the second frequency, and generating a comparison result; and (D) modulatingthe second frequency according to the comparison result and the frequency difference.

Description

technical field [0001] The present invention relates to a dynamic frequency compensation method and a dynamic frequency compensation system; specifically, the present invention relates to a dynamic frequency compensation method and a dynamic frequency compensation system of a display device. Background technique [0002] The signal received by the driver of the display device may become faster (or slower) due to the temperature change of the oscillator, which may cause abnormal reading and writing of display data by the driver. The existing method is to adopt temperature compensation, but there will be errors accumulated, resulting in abnormal situations in which the drive reads and writes display data. Therefore, existing practices need to be improved. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a dynamic frequency compensation method, which can reduce frequency variation. [0004] An object of the present invention is to provide a...
