Abstract

Embodiments of the present invention relate to the field of display technology, and disclose a display panel, a display device, and a detection method for the display panel. The display panel includes: an anode; a pixel defining layer disposed on the surface of the anode, and the pixel defining layer The area facing the anode is provided with a pixel opening, the pixel opening includes a first pixel opening and a second pixel opening, the second pixel openings are multiple, and the multiple second pixel openings are arranged at intervals to form a surrounding area. the annular structure of the first pixel opening, the first pixel opening and a plurality of the second pixel openings correspond to the same anode; the light emitting layer is located in the first pixel opening and at least part of the second pixel opening, so as to form sub-pixels one-to-one corresponding to the first pixel opening and at least part of the second pixel opening. The display panel, the display device and the detection method for the display panel provided by the present invention can accurately detect whether the display panel has defective pixels.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a display device, and a detection method for the display panel. Background technique [0002] OLED (Organic Light-Emitting Diode) is called organic electroluminescent diode. OLED display technology has many advantages such as all-solid-state, active light-emitting, high contrast, ultra-thin, low power consumption, fast effect speed, wide working range, easy to realize flexible display and 3D display, etc. , such as in televisions and mobile display devices. At present, the OLED display device still has the problem of having defective pixels, and the defects of the pixels mainly include the misalignment of the light-emitting layer of the pixel or the shadow of the light-emitting layer. [0003] The method for detecting defective pixels of an OLED display device in the prior art needs to be improved. Therefore, it is necessary to pro...
