Display screen, driving method and display device

Abstract

The invention discloses a display screen, a driving method and a display device.The display screen comprises a first screen provided with n rows of scanning lines, a second screen provided with m rows of scanning lines and a grid driving circuit, the second screen is tightly attached to the first screen, and the first screen is internally provided with scanning lines G1, G2 ... Gn-1,Gn in sequence from the side away from the second screen to the side close to the second screen, and the scanning lines gn, g2 ... gm-1, gm are sequentially arranged in the second screen from the side close to the first screen to the side away from the first screen. In the same frame, the moment when the gate drive circuit outputs the scanning signal of the scanning line G1 corresponds to the moment when the gate drive circuit outputs the scanning signal of the scanning line gm; the timing at which the gate drive circuit outputs the scan signal of the scan line Gn corresponds to the timing at which the scan signal of the scan line g1 is output. The two display screens scan oppositely, and the moments of the scanning signals of the scanning lines corresponding to the splicing position correspond to each other, so that the image discontinuity at the splicing position is improved, and better visual experience is brought to a user.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display screen, a driving method and a display device. Background technique [0002] With the rapid development of thin-film transistor liquid crystal displays, various manufacturers are actively adopting new technologies to improve the market competitiveness of products and reduce product costs. Among them, as a mainstream setting, the splicing screen can continuously increase the size of the display screen, and can be mass-produced at the same time during production, and a large-size display screen can be spliced ​​by multiple small screens. The price of glass is more cost-effective than that of a whole large display screen, and it is more convenient to operate in the process of forming a display screen. [0003] However, in the current splicing screen project, due to the combination of multiple identical display screens, when multiple display screens are scanned se...

Problems solved by technology

[0003] However, in the current splicing screen project, due to the combination of multiple identical display screens, when multiple display screens are scanned sequentially from the first scan line to the last scan line at the same time, the two splicing screens that are adjacent to each other up and down appear to be very different. The effect is that the picture that appears first at the bottom will appear discontinuous at the splicing point, which will affect the customer's visual experience
