Abstract

The invention discloses a display panel, its manufacturing method and a display device. The display panel includes: a base substrate, a plurality of pixels arranged in an array on the base substrate, and a detection circuit; wherein each pixel It includes a plurality of sub-pixels; the sub-pixels include: an infrared detection unit located on the base substrate, and a light-emitting unit located on the side of the infrared detection unit away from the base substrate; the light-emitting unit includes: a first electrode located on the base substrate, The second electrode located on the side of the first electrode away from the base substrate, and the display light-emitting part and the infrared light-emitting part stacked between the first electrode and the second electrode; the detection circuit is electrically connected to each infrared detection unit for The touch position is judged according to the photocurrent signal of each infrared detection unit. In the display panel provided by the embodiment of the present invention, the infrared detection unit and the infrared light emitting part do not occupy the aperture ratio of the pixel, which improves the resolution of the display screen.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have excellent characteristics such as high contrast, wide color gamut, fast response speed, and flexibility, which arouse the enthusiasm for commercial production in the flat panel industry and become the future display technology Competitor with the most development potential. Among them, Active-matrix organic light emitting diode (AMOLED) display panels have been widely used. [0003] With the gradual maturity of organic electroluminescence (OLED) display panel technology, and the simultaneous development of in-cell technology that integrates the touch screen sensing layer with AMOLED, AMOLED screens based on on-cell touch technology have been commercialized It has begun to be used in public services and personal entertainm...
