Abstract

The invention discloses a display panel, which includes an imaging area and a display sub-area surrounding the imaging area, and also includes a substrate; a thin film transistor layer arranged on the substrate; an organic light emitting layer arranged on the thin film transistor layer a groove, provided in the imaging region, the groove penetrates the thin film transistor layer and the organic light-emitting layer and extends to the inside of the substrate. The beneficial effect of the present invention is that the display panel of the present invention has a groove in the imaging area and fills it with a light-transmitting material, which improves the light transmittance of the light and improves the imaging accuracy. The groove adopts a structure with a wide top and a narrow bottom, which is beneficial to The fabrication and subsequent filling of fillers, while the structure with a wide top and a narrow bottom is also conducive to the packaging of the groove.

Description

technical field

[0001] The invention relates to the display field, in particular to a display panel. Background technique

[0002] At present, the development of display technology is changing with each passing day, and the emergence of various screen technologies provides infinite possibilities for electronic terminals. Especially with the rapid application of display technology represented by OLED (Organic Light Emitting Diode), various mobile terminals with selling points such as "full screen", "special-shaped screen", "under-screen sound" and "under-screen fingerprint" have begun to rapidly develop. promote.

[0003] Full screen technology is a relatively broad definition of the display industry for the design of mobile phones with ultra-high screen ratio. The literal explanation is that the front of the mobile phone is all screens, the display interface of the mobile phone is completely covered by the screen, and the four borders of the mobile phone are designed with ...
