Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be fully described below through specific implementation in combination with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts, All fall within the protection scope of the present invention.

[0029] Since the luminescent material of OLED displays has a certain attenuation, and the attenuation rate is relatively large in the initial use stage, and the attenuation rate area is stable in the subsequent use stage, an aging test is generally carried out before the OLED display leaves the factory to filter out the fast attenuation stage of the luminescent m...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display area and a peripheral circuit area. The display area is provided with a pluralityof scanning signal lines, a plurality of light-emitting control signal lines, a plurality of reference signal lines and a plurality of pixel circuits arranged in a matrix mode. The peripheral circuitarea is provided with a plurality of scanning driving circuits, a plurality of light emitting control circuits, a low potential signal line, a high potential signal line and a reference signal bus; the peripheral circuit region also comprises a plurality of aging test terminals; at least one of the low potential signal line, the high potential signal line and the reference signal bus is electrically connected with the two aging test terminals respectively; the two aging test terminals are connected with different aging test signals; it is guaranteed that in the aging test stage, the pixel units at the different positions of the display area have the same or similar luminance, the pixel units at the different positions have the same or similar aging speed, and it is guaranteed that the pixel units at the different positions of the display area have good display uniformity in the display stage.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode OLED (Organic Light Emitting Diode OLED) is one of the hotspots in the field of flat panel display research today. Compared with Liquid Crystal Display (LCD), OLED has low energy consumption, low production cost, self-illumination, wide viewing angle and corresponding At present, OLED has begun to replace traditional LCD in the field of flat panel displays such as mobile phones, PDAs, and digital cameras. [0003] However, the luminescent material of the OLED display has a certain attenuation, so an aging test is generally carried out before the OLED display leaves the factory. During the aging test, a large luminous signal is input to the OLED display to accelerate the attenuation process of the luminescent material. However, due to the resistance on the ...
