Problems solved by technology

[0006] However, due to the random saccades of the human eye, or the instinct to track moving objects in the screen, the color fields of the objects do not fall on the same point on the retina. Therefore, when using a color sequential display, the human eye will visually perceive objects The so-called Color Break Up phenomenon occurs at the edge, so that the user's visual experience is not good

Embodiment Construction

[0024] figure 1 It is a flow chart of the method for controlling the switching frequency of the color field of the color sequential display according to an embodiment of the present invention. Please refer to figure 1 , in this embodiment, the method for setting the frame update rate of the color sequential display includes the following steps. Detecting the frame input frequency of the input signal (step S110 ). Next, a plurality of frame reference frequencies are obtained after calculation according to an expression, wherein the above expression is the frame input frequency multiplied by a plurality of reference values, and these reference values ​​are related to the number of color fields of the color sequential display (step S120 ). Furthermore, the expression described in this implementation is fi×(n±k / s), where fi is the screen input frequency of the input signal, s is the number of color fields of the color sequential display, n and k are positive integers, respective...

Abstract

The invention relates to a method for controlling a color field switching frequency of a color sequence display. The method comprises the following steps of: detecting a picture input frequency of an input signal; calculating according to an expression so as to obtain a plurality of picture reference frequencies, wherein the expression is that: the picture input frequency multiplies the plurality of reference values, and the reference values are associated with the number of color fields of the color sequence display; and selecting one of the picture reference frequencies and adjusting the color field switching frequency of the color sequence display according to the selected picture reference frequency.

Description

technical field [0001] The present invention relates to a control method, and in particular to a control method of the color field switching frequency of a color sequential display. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of Flat Panel Display. Among many flat panel displays, Liquid Crystal Display (LCD for short) has high space utilization efficiency and low power consumption. , no radiation and low electromagnetic interference and other superior characteristics, it has become the mainstream of the market. [0003] According to the color mixing method of the liquid crystal display, it can be roughly divided into two types: temporal color mixing and spatial color mixing (also known as juxtaposition addition or simultaneous addition). At present, most common displays are spatial juxtaposition and additive color mixing. Taking Thin-Film Transistor Liquid Crystal Display (TFT...
