Display panel and display device

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. In the embodiment of the invention, for the display panel having a double-gate structure, acolumn of sub-pixels are arranged between any adjacent two data lines; furthermore, each data line is electrically connected with adjacent various sub-pixels at one side, and insulated from adjacentvarious sub-pixels at the other side; therefore, the coupling influence Cpd of each sub-pixel by the data line is same; therefore, the vertical stripe phenomenon due to the fact that the coupling influence Cpd of the sub-piexel by the data line around is different can be eliminated; the display effect is improved; furthermore, the routing increasing problem in a fan-out area also can be avoided; therefore, the area of the fan-out area is easily reduced; the screen-to-body ratio is increased; in addition, because a touch signal line and the data line are in the same layer and arranged to be insulated, an embedded touch structure can be realized; the thickness of the display panel is reduced while the touch detection precision is increased; and thus, lightweight design is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The display mainly includes liquid crystal display and electroluminescent display. The liquid crystal display is a non-self-luminous device, which needs to be equipped with a backlight module, and the backlight provided by the backlight module is used to realize the display function; the electroluminescent display is different from the liquid crystal display. A light-emitting display is a self-luminous device that does not need a backlight module, that is, a display function can be realized without a backlight source. Therefore, an electroluminescent display can be made thinner and lighter. At present, both liquid crystal displays and electroluminescent displays are widely used. [0003] In order to increase the screen-to-body ratio of the display, the display panel can be designed as a double-gate structure, s...

Problems solved by technology

[0006] Although the vertical stripes caused by the polarity of the data signal can be solved by setting two columns of sub-pixels electrically connected to the same data line, but for a certain column of sub-pixels, data adjacent to the column of sub-pixels will appear. The line is not a data line electrically connected to the sub-pixels of this column, so that each sub-pixel is affected by the coupling influence (indicated by Cpd) of the data line electrically connected to itself and the data line adjacent to it to a different degree, and the Cpd will still be affected by the coupling. Vertical stripes appear, resulting in a decrease in display effect
