Abstract

The invention provides a display making method. The making method comprises the following steps: a backplane, a first transfer platform and a second transfer platform are firstly provided, wherein multiple first light emitting modules are arranged on the first transfer platform, and multiple second light emitting modules are arranged on the second transfer platform; then, multiple first joint layers are formed at multiple first positions on the backplane, and later, the first transfer platform is in butt joint with the backplane to enable the first light emitting modules corresponding to the first positions to be joined at the first positions with the help of the first joint layers; then, multiple second joint layers are formed at multiple second positions on the backplane, and later, thesecond transfer platform is in butt joint with the backplane to enable the second light emitting modules corresponding to the second positions to be joined at the second positions with the help of thesecond joint layers. Thus, multiple light emitting modules with different colors can be quickly and accurately arranged on the backplane of the display, the display making cost is low, and the yieldis high.

Description

technical field [0001] The invention relates to a manufacturing method of a display, in particular to a manufacturing method of a light emitting diode display. Background technique [0002] With the advancement of optoelectronic technology, the volume of many optoelectronic components is gradually miniaturized. In recent years, due to breakthroughs in the size of light-emitting diodes (light-emitting diodes, LEDs), light-emitting diode (micro-LED) displays, which are made of light-emitting diodes arranged in arrays, are gradually gaining attention in the market. Light-emitting diode displays are active light-emitting component displays. In addition to saving power compared to organic light-emitting diode (OLED) displays, they also have better contrast performance and can be used in sunlight Has visibility. In addition, since the light-emitting diode display uses inorganic materials, it has better reliability and a longer service life than the organic light-emitting diode d...
