Embodiment Construction

[0045] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0046] The present invention provides a solution to the problem that the existing OLED display screen cannot realize in cell touch.

[0047] On the one hand, an organic electroluminescent display panel of the present invention, such as figure 1 shown, including:

[0048] substrate substrate 1;

[0049] A plurality of photosensitive elements 2 formed on the base substrate 1;

[0050] A plurality of touch detection units 3, each touch detection unit 3 is composed of at least one photosensitive element 2 ( figure 1 Take two photosensitive elements forming a touch detection unit as an example);

[0051] The signal input line 4 and the signal output line 5 correspond one-to-one to the touch detection unit 3 . The signal input line 4 is connected to the i...

Abstract

The invention provides an organic light-emitting device (OLED) display panel, a display device and a manufacturing method. The OLED display panel comprises a substrate, multiple photosensitive elements formed on the substrate, multiple touch control detection units, and signal input lines and signal output lines in one-to-one correspondence with the touch control detection units, wherein each touch control detection unit is formed by at least one photosensitive element; the signal input line is connected with the input end of the photosensitive element in the corresponding touch control detection unit for loading touch control detection signals from the touch control circuit; and the signal output line is connected with the output end of the photosensitive element in the corresponding touch control detection unit for outputting current of the photosensitive element to the touch control circuit, and thus, the touch control circuit can recognize touch control operation according to current changes of the photosensitive element. In cell touch is realized on the OLED display device, and compared with the existing OLED display product, the OLED display panel of the invention has a smaller box thickness.

Description

technical field [0001] The present invention relates to the field of touch display, in particular to an organic electroluminescent display panel, a display device and a manufacturing method. Background technique [0002] OLED display (organic electroluminescent display) has the characteristics of high contrast, thin thickness, wide viewing angle, fast response speed, etc., and has begun to gradually replace LCD display (liquid crystal display). [0003] OLED display screens in the existing market can only provide display functions, and need to be attached to an additional touch screen to realize the touch function. ) compared to the LCD without the thickness advantage. [0004] At present, the capacitive touch structure produced by depositing metal and insulating layers on the TFE (tetrafluoroethylene) packaging film by low-temperature sputtering has a very low product packaging yield. [0005] In view of this, there is an urgent need for a technical solution for realizing...
