Embodiment Construction

[0025] The embodiment of the present application provides a touch display panel, such as figure 1 , figure 2 As shown, figure 1 Is a schematic diagram of a touch display panel provided by an embodiment of the present application, figure 2 Yes figure 1 Enlarged view of middle area 19. The touch display panel in the embodiment of the present application is divided into a display area 3 and a non-display area 21 surrounding the display area. In this embodiment, the shape of the touch display panel is rectangular, and the shape of the display area 3 is non-rectangular, that is, the touch display panel provided by the embodiment of the present application is a touch display panel with irregular display. Such as figure 1 , figure 2 The touch display panel shown includes a driving circuit 1, pixel units 20 arranged in an array, touch electrodes 2 arranged in an array, and a plurality of leads 4 extending in a first direction Y and arranged in a second direction X. Such as figure 1 ...

Abstract

The invention discloses a touch control display panel and a display device. The touch control display panel and the display device are used for avoiding the nonuniform display caused by the nonuniformlead distribution. The touch control display panel comprises a drive circuit, array-arranged pixel units, array-arranged touch control electrodes and multiple leads. Each touch control electrode is at least electrically connected with the drive circuit through one lead. Each pixel unit comprises multiple pixel unit columns, and each touch control electrode comprises multiple touch control electrode columns. The number of the leads is the same as the number of the pixel unit columns, and the leads are uniformly arranged in the range covered by the orthographic projection of a first plane. Thenumber of the leads covered by the orthographic projection of each touch control electrode column in the first plane is the same. Each touch control electrode column comprises at least one first touchcontrol electrode column and at least one second touch control electrode column, the number of the touch control electrodes in the first touch control electrode column is greater than the number of the touch control electrodes in the second touch control electrode column. The total number of the leads electrically connected with the touch control electrodes in each first touch control electrode column is equal to the total number of the leads electrically connected with the touch control electrodes in each second touch control electrode column.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to a touch display panel and a display device. Background technique [0002] The touch display panel in the prior art is generally a regular rectangular display panel, including a display area and a non-display area. The touch leads in the touch display panel connect the touch electrodes and the integrated circuit (IC) through vias. For connection, for a display panel with a regular rectangular display area, the corresponding touch electrode array is rectangular, and the arrangement of touch leads can be evenly distributed in the display panel. With the demand for full-screen display of display products, more and more products require special-shaped display on the panel to avoid cameras, etc. However, in a touch display panel with special-shaped display, the shape of the display area is non-rectangular, and the shape of the corresponding touch electrode array It is also non-rect...
