Active display device and driving method thereof

Abstract

An active display device comprises a sub-pixel array and a sub-pixel array driving circuit; all of the sub-pixels of the same column in the sub-pixel array are connected with the same data line, each data line is connected with and located between two adjacent columns of sub-pixels, two columns of sub-pixels are arranged between two adjacent data lines; each line of sub-pixels correspond to two scanning lines, the sub-pixels of odd-numbered columns in the same line are connected to one of the scanning lines, the sub-pixels of even-numbered columns in the same line are connected to the other one of the scanning lines, and the sub-pixels connected with each data line are disposed in the same line. When driving, the sub-pixels of odd-numbered columns in the same line are controlled by one scanning line, and the sub-pixels of even-numbered columns in the same line are controlled by the other scanning line. The number of the scanning lines is decreased by half compared with the traditional organic display device, the column inversion and the point inversion of the polarity of the sub-pixel array can be realized, and thereby improving the process yield, reducing the cost and improving the display effect while realizing the high fining.

Description

technical field [0001] The invention relates to an active display device and a driving method thereof. Background technique [0002] With the popularization and development of 3G technology, the application of mobile TV, mobile Internet movies, video calls, etc., has higher and higher requirements for the multimedia functions of mobile terminals. Good direction. [0003] In order to achieve higher refinement, the technical means currently used mainly include: (1) Manufacturers of display devices obtain higher process capability and finer line width and line spacing inside display devices by upgrading equipment and improving processes , but this method greatly increases the cost of the display device; (2) IC chip manufacturers consider the cost reduction pressure to make the area of ​​IC (integrated circuit) smaller and smaller, and the spacing of IC pins is therefore Taking the current TFT driver IC as an example, it is changing from the typical design of single-sided doub...

Problems solved by technology

The sub-pixel array driving circuit of the traditional TFT-LCD is that the sub-pixels in the same row are controlled by the same scanning line, and the same data line only controls the sub-pixels in the same column. The VCOM inversion mode is used for display driving, which can realize the sub-pixel Frame inversion and row inversion of array polarity to reduce driving power consumption, but the VCOM inversion method can only control the sub-pixels in the same row at the same time, and the sub-pixels in the same row are all in the same polarity voltage difference, Only the frame inversion and row inversion of the polarity of the sub-pixel array can be realized, but the column inversion and dot inversion of the sub-pixel array cannot be realized, which is prone to crosstalk and flicker, making the display effect significantly changed.
