Embodiment Construction

[0046] Those skilled in the art understand that those skilled in the art can implement the variation example in combination with the prior art and the foregoing embodiments, which will not be repeated here. Such variations do not affect the essence of the present invention, and will not be repeated here.

[0047] figure 1It shows a flow chart of color enhancement of the display input data in the drive circuit according to a specific implementation manner of the present invention to expand the number of display gray scales, specifically, the steps are as follows:

[0048] First enter step S101, split the display input data received by the drive circuit, and obtain a plurality of split intermediate display data. Those skilled in the art understand that the display input data refers to the target gray scale, so The target gray scale can be obtained by taking the average value of the gray scale values ​​of a plurality of different sub-pixels. Specifically, in the present inventio...

Abstract

The invention provides a color enhancement algorithm for expanding number of displayed gray scales, wherein the color enhancement algorithm is used for adjusting the gray scales of displaying input data for obtaining displaying output data. The color enhancement algorithm comprises the steps of a, dividing the displaying input data which are received by a driving circuit, and obtaining a plurality of packets of intermediate displaying data after dividing; b, performing data bit expansion on at least one packet of intermediate displaying data in the plurality of packets of intermediate displaying data, so that the data length of the processed intermediate displaying data is increased and furthermore expanded displaying data are obtained; c, performing jitter processing on the expanded displaying data and the unprocessed intermediate displaying data and obtaining a plurality of packets of jitter-processed displaying data; and d, combining the plurality of packets of jitter-processed displaying data, thereby obtaining displaying output data.

Description

technical field [0001] The present invention relates to a color enhancement control system, in particular to a color enhancement algorithm for expanding the number of displayed gray scales, in particular to a control of a color enhancement algorithm based on Hi-FRC (High-FrameRateControl) pixel dithering to expand the number of displayed gray scales method and corresponding control device. Background technique [0002] With the continuous progress of the times and the continuous development of society, people have higher and higher requirements for display devices such as TVs, mobile phones, and computers. Especially now, we are often no longer limited to using photos, pictures, etc. to record our In daily life, mobile phones, digital cameras, computers and other electronic products can quickly, efficiently and permanently store our image information. With the continuous advancement of electronic technology, people's demand for images is also increasing. For example, people ...
