Micro light emitting diode array substrate and display panel

Abstract

Provided is a micro light emitting diode array substrate. The array substrate comprises a glass substrate (1) sequentially formed with a gate (2) and an insulation layer (3) thereon. A semiconductor layer (4) and pixel electrode (5) are formed on the insulation layer (3). A source (6) and drain (7) are provided on the semiconductor layer (4). The drain (7) is connected to the adjacent pixel electrode (5). The pixel electrode (5) is covered with a first electrically conductive layer (8), and the first electrically conductive layer (8) is connected to a micro light emitting diode (9) thereon. Also provided is a display panel comprising a CF substrate and the micro light emitting diode array substrate. Compared with the prior art, the present invention enables, by means of coating an electrically conductive layer between a pixel electrode and a micro light emitting diode, heat from the micro light emitting diode to be transferred to other regions via the electrically conductive layer, thus improving heat dissipation.

Description

technical field [0001] The invention relates to the technical field of micro-light-emitting diode display, in particular to a micro-light-emitting diode array substrate and a display panel. Background technique [0002] Flat panel display devices are widely used in various consumer electronics such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers due to their advantages of high image quality, power saving, thin body, and wide application range. products, becoming the mainstream of display devices. [0003] A Micro LED (μLED) display is a display that uses a high-density micro-sized LED array integrated on a substrate as display pixels to display images. Like a large-size outdoor LED display, each pixel Addressable and individually driven to light up, it can be regarded as a reduced version of the outdoor LED display, reducing the pixel distance from millimeters to microns. μLED displays are the same as Or...

Problems solved by technology

[0004] At present, the micro-light-emitting diode display array shows the micro-light-emitting diode array structure designed above the driving array. The conductive connection of the array is to be driven through the positive and negative electrodes, and the switch and brightness of the micro-light-emitting diodes of each pixel are controlled by the TFT array. The display unit has become the mainstream current control technology. This kind of thin film transistor forms a current channel between the source and drain through the gate control, so that the sub-pixel storage capacitor is charged to maintain the continuous (Holdtype) display of the liquid crystal. mode; and micro-LED array due to its micron scale, when in order to achieve a high pixel number (PPI) display, it will lead to a very high density of micro-LEDs, so that it has the problem of poor heat dissipation
