Back contact type full-color LED display panel and manufacturing method thereof

Abstract

The invention mainly provides a back contact type full-color LED display panel, which is characterized in that M * N LED light-emitting structures are formed on a setting surface of a double-sided polishing light-transmitting substrate, and an edge layer is formed on the setting surface and covers the LED light-emitting structures. M * N first conductive columns and M * N second conductive columnsare further manufactured in the insulating layer and used for being connected to M * N first semiconductor material layers and M * N second semiconductor material layers of all the LED light-emittingstructures respectively. In addition, the light conversion unit is arranged on a light-emitting surface of the double-sided polishing light-transmitting substrate. After the back contact type full-color LED display panel is inverted, a driving circuit module with M * N first electrodes and M * N second electrodes can be electrically connected with the first conductive columns and the second conductive columns. Therefore, the back contact type full-color LED display panel does not need to use any transparent conducting layer, so that the load effect derived by the driving circuit module in theprocess of executing display driving can be reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of self-luminous display panels, in particular to a back-contact full-color LED display panel and a manufacturing method thereof. Background technique [0002] It is known that existing types of flat panel displays include liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, and organic light-emitting diode (LED) displays. Engineers who are familiar with the design and production of display panels must know that liquid crystal displays have disadvantages such as non-self-illumination, low efficiency, low dynamic range, and the need for polarization filters. Although OLED displays are self-illuminating displays, however, the low reliability and low efficiency (~5% QE) of blue OLED components have become the main defects of OLED displays. [0003] On the contrary, the production technology of red, green, and blue LED components is very mature, making LED displays have the advantages o...

Problems solved by technology

Electronic engineers who are familiar with the design and production of display driver chips should understand that the relatively high resistance of the electrodes connected to the anode terminals and the electrodes connected to the cathode terminals will inevitably generate unpredictable load effects, resulting in the inability of the display driver chip to drive perfectly. Each sub-pixel of the LED display panel (that is, the LED component), thus reducing the user experience (User experience, UX)
