Problems solved by technology

At present, conventional products are usually equipped with a multi-channel selector, and the charging time of the corresponding gate scanning signal is generally less than 0.5 microseconds; while high-frequency products adopt the structure of conventional products, the charging time of the gate scanning signal is also less than 0.5 microseconds. 0.5 microseconds, at this time, the charging time of the grid scanning signal is seriously insufficient, and vertical lines are prone to appear when displaying the screen, and the display effect is reduced

Embodiment Construction

[0040] Specific implementations of a display panel, a driving method thereof, and a display device provided by embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The inventor found in the research that for a display without a multiplexer (such as demux), such as a display designed with hipin, when a conventional product (such as a product with a scanning frequency of 60Hz) displays a frame, the corresponding The time is generally 16.67ms. If the resolution of this product is 1080*2340, the time to scan a line of pixels is 16.67ms / 2340, that is, the time to s...

Abstract

The invention discloses a display panel, a driving method thereof and a display device. The method comprises the following steps: firstly, reducing the area, occupied by a lead corresponding to a dataline, of a non-display region through setting a multiplexer, thereby enabling the non-display region to be narrower, and achieving the design of a high screen-to-body ratio and a narrow frame; moreover, a plurality of shift register groups are arranged; the shift registers in the shift register groups can output the grid scanning signals respectively, so that the charging time of the grid scanning signals can be prolonged, vertical stripes caused by short charging time of the grid scanning signals can be eliminated while high-frequency display is realized, and the display effect is improved.Besides, since the end time of the second time is earlier than the start time of the third time, overlapping of the second time and the third time can be avoided, and input of data signals in the initialization stage of the (i + N + 1) th row of first pixels is further avoided, so that normal and effective driving of the display panel is guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a driving method thereof and a display device. Background technique [0002] The electroluminescent display is a self-luminous device, which can realize the display function without setting a backlight module, which makes the display have the characteristics of light weight and thinness, and has a wide range of applications in various fields. [0003] Electroluminescent displays generally have two specifications: conventional products and high-frequency products. Conventional products can be understood as products with a scanning frequency of 60 Hz, and high-frequency products can be understood as products with a scanning frequency of 120 Hz. At present, conventional products are usually equipped with multiplexers, and the charging time of the corresponding gate scanning signal is generally less than 0.5 microseconds; and if the high-frequency produ...
