And those tiny light-emitting diodes used in backlight modules require high power consumption
As a result, when the temperature increases, the efficiency of the micro-LEDs decreases due to the thermal accumulation effect, which causes the aging of the color conversion layer (eg, color filter material layer)

Abstract

The invention provides a miniature light emitting display and a manufacturing method thereof. The miniature light-emitting display comprises a first transparent miniature cap disposed on a substrate.The first transparent miniature cap comprises a first flat plate part arranged opposite to the substrate and a first cofferdam part located between the substrate and the first flat plate part. The substrate, the first flat plate part and the first cofferdam part form a first cavity. The first cavity is vacuum or filled with air or inert gas. The miniature light emitting display further comprises afirst miniature light emitting device which is arranged on the substrate and located in the first cavity. In addition, the miniature light emitting display comprises a first color material layer which is arranged on the first flat plate part and corresponds to the first miniature light emitting device.

Description

technical field [0001] Embodiments of the present invention relate to a display technology, and in particular to a micro light-emitting display with a thermal insulation structure and a manufacturing method thereof. Background technique [0002] Conventional light-emitting diodes typically have dimensions of several hundred micrometers. In comparison, miniature light-emitting diodes are on the order of tens of microns or smaller in size. Micro LEDs are popular in electronics due to their high brightness, high contrast ratio, wide viewing angle, long lifetime, and low power consumption. [0003] Attempts have been made to use monochrome miniature LEDs in backlight modules. And those tiny LEDs used in backlight modules require high power consumption. As a result, when the temperature rises, the performance of the micro-LEDs decreases due to the thermal accumulation effect, which causes the aging of the color conversion layer (eg, the color filter material layer). [0004] ...
