Abstract

The invention provides a display device. The display device includes a driving substrate and a plurality of micro light emitting elements. The driving substrate has a plurality of pixel regions. The micro light emitting elements are configured in the pixel regions of the driving substrate and are electrically connected to the driving substrate. Each pixel region is provided with a plurality of micro light emitting elements. The orthographic projection areas of the micro light emitting elements in each pixel region on the driving substrate are the same. At least two micro light emitting elements in each pixel region have different effective light emitting areas.

Description

technical field [0001] The invention relates to a display device, in particular to a display device using micro light-emitting elements as display pixels. Background technique [0002] With the advancement of optoelectronic technology, the volume of many optoelectronic components is gradually miniaturized. Due to breakthroughs in the size of light-emitting diodes (LEDs) in recent years, micro-LED displays, which are made of light-emitting diodes arranged in an array, are gradually gaining attention in the market. However, the micro-LEDs are relatively unstable in terms of electrical performance and luminous wavelength, so they tend to have a large leakage problem. In addition, in order to balance the influence of human eyes on color perception and improve display quality, LEDs of different colors in each pixel area have different sizes. However, the process of transferring light emitting diodes of different sizes from the carrier substrate to the receiving substrate is tro...
