Problems solved by technology

[0007] Although the drive circuit design based on the aforementioned shared data lines reduces the number of data lines and data drivers used, it also increases the number of thin film transistors, resulting in a decrease in the aperture ratio and a half of the frequency. If there is a black screen insertion effect, the frequency increases. up to 4 times

Embodiment Construction

[0041]The present invention proposes a display panel with a time multitasking driving circuit and its driving method, which utilizes a driving method in which two adjacent pixels in the same column share one data line, so that two adjacent pixels only use two thin film transistors as switches. Yes, three transistor switches are required to effectively replace the conventional sharing of data lines between adjacent pixels, so the number of data lines and the number of transistor switches can be reduced at the same time, thereby achieving the effects of reducing cost and increasing aperture ratio. In addition, it can also be combined with the technology of inserting black screens to improve the dynamic quality of the displayed screen.

[0042] see image 3 As shown, as shown in the figure, the figure shows a partial schematic diagram of a driving circuit for two adjacent pixels sharing data lines of the present invention. A plurality of parallel scanning lines S1-Sm and a plural...

Abstract

The invention discloses a display panel provided with a time multi-task drive circuit and the drive method thereof. The display panel comprises a plurality of scanning beams and data lines which are mutually vertical, a first pixel connected to a scanning beam and a data line, and a second pixel respectively connected with another scanning beam to ensure the first pixel and the second pixel to share the same data line; the second pixel is respectively controlled by a first switch and a second switch to selectively and respectively transmit a first data signal and a second data signal into thefirst pixel and the second pixel. The invention achieves the effects of reducing the cost and increasing the aperture ratio through reducing the quantities of the data lines and the switches; can also improve the dynamic quality of images by being combined with black screen insertion technology.

Description

technical field [0001] The present invention relates to a display panel, in particular to a display panel with a time multitasking driving circuit and a driving method thereof, which can also be combined with a black image insertion (Black image insertion) technology at the same time. Background technique [0002] Liquid crystal displays take advantage of their characteristics such as thinness, light weight, low power consumption, and no environmental burden, and have a relatively high usage rate in various application fields. Common liquid crystal displays usually use active matrix driving circuits to control the movement of the display panel, and with the vigorous development of display technology, how to improve display quality and reduce costs are two major issues that the industry is currently striving to overcome. [0003] Schematic diagram of a general active matrix drive circuit figure 1 As shown, in the active matrix liquid crystal display panel 100, each pixel 10 ...
