Display panel and display device thereof

Abstract

Embodiments of the present invention provide a display panel and a display device thereof, which relate to the field of display technology and are used to prevent light-stealing between light-emitting elements of different colors in an OLED display panel. The display panel includes a base substrate; the base substrate is provided with a plurality of gate lines extending in the row direction and a plurality of data lines extending in the column direction, and the gate lines and the data lines are insulated to cross to define a plurality of pixel circuit areas, and the pixel circuit The area includes a pixel circuit; a plurality of sub-pixel areas are also provided on the base substrate, and each sub-pixel area includes a light-emitting element, and the pixel circuit provides a driving signal for the light-emitting element; wherein, the light-emitting element includes an anode, an The light-emitting layer and the cathode; the base substrate is also provided with a plurality of light-emitting control signal lines extending along the row direction and insulatingly overlapping with the data lines; between the anode and the gate lines and / or light-emitting control signal lines extending along the row direction do not overlap. The above display panel is applicable to a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device thereof. Background technique [0002] Compared with many display panels, the OLED (Organic Light-Emitting Diode, hereinafter referred to as OLED) display panel has many advantages such as active light emission, high contrast ratio, and no viewing angle limitation. OLED display panels are not only lighter and thinner in size, but also lower in power consumption than other display devices, which helps to improve the battery life of display devices. Therefore, OLED display panels are widely used in the field of display technology and will become the future of display devices. mainstream products. [0003] Currently, a common OLED display panel includes an organic light emitting element with a red light emitting color, an organic light emitting element with a green light emitting color, and an organic light emitting element with a blue ...

AI Technical Summary

Problems solved by technology

[0004] However, since the turn-on voltages of the three light-emitting elements with different light-emitting colors are different, when the light-emitting element with a higher turn-on voltage is turned on, the carriers move laterally through the common film layer, causing the remaining light-emitting colors and light-emitting elements that have not been turned on to steal light. , not only increases power consumption, but also affects the display effect

[0005] Therefore, how to avoid the problem of light-stealing between light-emitting elements of different colors in the OLED display panel, thereby reducing power consumption and improving the display effect is the main technical problem currently faced by the industry.
