Problems solved by technology

However, due to the unavoidable layering and cross-line structure between metals in the panel design, there will inevitably be some parasitic capacitance, such as the parasitic capacitance between the data line and the pixel electrode. The existence of parasitic capacitance will affect the display of the panel. Effect
When the parasitic capacitance between the data line and the pixel electrode is too large, it will cause undesirable problems such as vertical crosstalk on the panel

Abstract

The embodiment of the invention provides a display panel and a mobile terminal. The display panel comprises a plurality of sub-pixels, each sub-pixel comprises a pixel electrode and a common electrode arranged on the different layer of the pixel electrode, and in the top view direction of the display panel, the orthographic projection of the common electrode on the pixel electrode coincides with the pixel electrode; according to the display panel, the orthographic projection, on the pixel electrode, of the common electrode in each sub-pixel coincides with the pixel electrode, so that the overlapping area of the common electrode and the pixel electrode in the direction perpendicular to the display panel is increased, and then the load capacitance of the pixel electrode is increased; therefore, stray capacitance generated between the data lines and the pixel electrodes is further reduced, the vertical crosstalk phenomenon of a picture of the display panel is prevented, and the display effect of the display panel is further improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a mobile terminal. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display devices such as liquid crystal display panels (Light Emitting Diode Panel) have been widely used as display components in electronic products such as mobile phones, digital cameras, and personal digital assistants. [0003] At present, thin film transistors (Thin Film Transistors) are widely used in liquid crystal display panels. However, due to the inevitable existence of stacking and cross-line structures between metals in panel design, there will inevitably be some parasitic capacitances, such as parasitic capacitances between data lines and pixel electrodes. The existence of parasitic capacitances will affect the display of the panel. Effect. When the parasitic capacitance between the data line and ...
