Abstract

The invention discloses a GOA type display panel and its driving circuit structure and driving method. The driving circuit structure includes: a plurality of scanning lines; a first control circuit configured to control all odd-numbered scanning lines in the plurality of scanning lines Turning on and off scanning lines or all even-numbered scanning lines; a second control circuit configured to realize different connection modes between all pairs of odd-even scanning lines in the plurality of scanning lines in different display modes, the display The modes include a two-dimensional display mode and a three-dimensional display mode, wherein in the three-dimensional display mode, dual scanning lines are simultaneously turned on. In the present invention, two control circuits are added between the GOA circuit area and the AA area, and the two circuits are used to realize 2D normal display and simultaneously open double gates in 3D display. In addition, the circuit can be realized only by using two vacant pins of the source driver IC, and no additional design is needed, thereby reducing the cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a GOA type display panel, a driving circuit structure and a driving method thereof. Background technique [0002] In the prior art, the driving circuit in the liquid crystal display is mainly completed by connecting an integrated circuit (Integrated Circuit, IC) outside the liquid crystal panel. In contrast, the Gate Driver on Array (Gate Driver on Array) technology, referred to as GOA technology, is a technology that directly manufactures Gate Driver ICs on the array substrate to replace the driver chips made of external silicon chips. technology. Since the GOA circuit can be directly fabricated around the panel, the manufacturing process is simplified, the product cost can be reduced, and the integration degree of the liquid crystal panel can be improved, so that the panel tends to be thinner. [0003] Currently, the mainstream 3D display technologies on the ma...

Problems solved by technology

[0005] Because the control circuit required by the scan switch technology and the dynamic area switch technology is more complicated and the cost is higher, a solution to reduce crosstalk by using black insertion technology between the left and right eye signals is proposed

However, since the shutter-type 3D technology uses left and right eyes to alternately receive signals, the frame rate (Frame rate) is generally required to be 120Hz, and after the black insertion technology is used, the frame rate must be doubled. The impact of charging is serious, so it is proposed to use dual-gates to be turned on at the same time during 3D display to reduce the resolution in the scanning direction and improve the charging time. Add a new complex design to the pole circuit (Gate IC) to achieve the above functions
