Abstract

The present application discloses an OLED display panel, including: a base substrate, the base substrate includes a first surface and a second surface oppositely arranged, and the display panel further includes a sensor located on the first surface of the base substrate ; It also includes a pixel definition layer including an opening area and a non-opening area; a plurality of spacers are arranged in the non-opening area; the sensor is arranged in a display area, and the display panel includes a first area; the rest of the display area The area is the second area; the first area covers the boundary of the sensor; the display panel also includes a packaging substrate, and the contact area between the spacer in the first area and the packaging substrate is the first area; The contact area of ​​the spacer in the second region with the packaging substrate is a second area, and the first area is smaller than the second area. The display panel of the present application can reduce the probability of contact between the boundary of the sensor area and the spacer, and improve the reliability of the display panel.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. 【Background technique】 [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is also called organic electro-laser display, organic light-emitting semiconductor. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high response speed. OLED display technology is widely used in mobile phones, digital video cameras, DVD players, personal digital assistants (PDAs), notebook computers, car audio and televisions. Since the OLED display device does not need to provide an additional backlight, the OLED display device is very thin and light. And because OLEDs can be made into flexible organic light-emitting display devices, OLEDs are widely used in foldable display technologies. [0003] As the functions of displ...
