Problems solved by technology

[0004] However, each method of polarity inversion has advantages over the others, as well as unavoidable disadvantages
For example, the column inversion method is excellent in eliminating the data delay of the data line and reducing power consumption, but it may cause vertical flickering and vertical crosstalk to reduce the image quality
The frame inversion method saves the most power consumption, but the image quality is the worst
The point inversion method performs best against crosstalk, but consumes the most power
[0005] In other words, among the various existing polarity inversion methods mentioned above, none of them can have optimal performance in terms of display effect (such as crosstalk elimination) and power consumption.
In addition, these polarity inversion methods cannot be adjusted and matched according to different design requirements and application conditions (such as device characteristics).

Embodiment Construction

[0027] Please refer to figure 1 , which shows a block diagram of a display driving circuit according to an embodiment, which can be applied in a display device 100 . The display driving circuit 1 is used for providing display data to drive the display 2 to display corresponding image frames. The display driving circuit 1 includes a timing circuit 10 and a data driver 12 . The timing circuit 10 is used for generating a timing control signal S_ctrl. The timing control signal S_ctrl usually includes a variety of signals, such as control signals, clock signals, data signals, polarity control signals, etc., for controlling the data driver 12 to receive display data and provide the received display data to the display 2 The corresponding data lines on the display, and timely adjust the polarity of the display data.

[0028] A unique feature of this embodiment is that the display driver circuit 1 can switch between multiple different types of polarity switching methods. In other ...

Abstract

The invention discloses a multi-type polarity inversion driving method, and an application circuit thereof and an application device thereof. The method is used for driving a displayer, can be converted with different types of polarity inversion driving methods, and can also flexibly cooperate with various design requirements and application conditions to adjust. The driving method comprises the step of providing display data by taking a polarity inversion switching time unit as a repeated time unit. The polarity inversion switching time unit is provided with a plurality of polarity distribution form intervals with different types. In the different types of polarity distribution form intervals, the provided display data has different types of polarity distribution forms on one displayer.

Description

technical field [0001] The present invention relates to a polarity inversion driving method, and in particular to a multi-type polarity inversion driving method that can be switched among different types of polarity inversion methods. Background technique [0002] In today's era of rapid technological development, liquid crystal displays have been developed and widely used in various applications. Generally speaking, the characteristics of the liquid crystal molecules (Liquid Crystal cells) in a liquid crystal display cannot be fixed at a certain voltage. The electric field changes to rotate to form different gray scales. Accordingly, the voltage must be restored to its original state at regular intervals to avoid damage to the properties of the liquid crystal molecules. [0003] Therefore, different types of polarity inversion driving methods have been developed. For example, there is a frame inversion method, which inverts the polarity of the display data provided to th...
