Embodiment Construction

[0027] The micro-LEDs mentioned in this article refer to LEDs with a size in the range of about 1 μm to 100 μm, more precisely, LEDs with a size smaller than 100 μm; the photodiodes mentioned in this article refer to photoelectric sensing devices that convert optical signals into electrical signals .

[0028] Figure 1A It is a schematic diagram of a micro-LED touch display panel according to a preferred embodiment of the present invention. Such as Figure 1A As shown, the micro LED touch display panel 10 includes a substrate 200 and a plurality of micro LEDs 31 and a plurality of photodiodes 32 located on the substrate 200 . In this embodiment, the plurality of micro-LEDs 31 emit light in a forward bias state, and the plurality of photodiodes 32 sense light brightness changes in a negative bias state to detect touch positions.

[0029] Specifically, each micro LED 31 includes an anode and a cathode, and the forward bias state means that the potential of the anode of the micr...

Abstract

A miniature LED touch display panel comprises a plurality of miniature LEDs and further comprises a plurality of photodiodes, and the photodiodes detect the touch position by sensing the change of illumination intensity. According to the micro LED touch display panel provided by the embodiment of the invention, the plurality of photodiodes are arranged, and the touch position is detected accordingto the change of the light signal sensed when the plurality of photodiodes touch the upper part of the micro LED touch display panel or not, so that a touch technology is integrated into the micro LED display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a micro LED touch display panel. Background technique [0002] Micro-LED (Micro Light Emitting Diode) display technology, also known as micro LED or μLED display technology, is an emerging flat panel display technology. At present, the micro-LED panel is a transparent conductive film connected to an N-type doped phosphor layer, which is connected to the ground through a metal wire, and a P-type doped phosphor layer is connected to a positive potential through a metal wire to light up the light. diode. However, the current micro-LED display panels do not incorporate touch technology. Contents of the invention [0003] In view of the above, it is necessary to provide a micro LED touch display panel. [0004] The micro LED touch display panel provided by the embodiment of the present invention includes a plurality of micro LEDs, and the plurality of micro LEDs emit light in a ...
