Abstract

A micro light emitting diode display device includes a first substrate and a second substrate which are oppositely arranged. A plurality of micro light emitting diodes are respectively disposed at adjacent surfaces of the first substrate and the second substrate, whereby the micro light emitting diodes are disposed with high density to improve the resolution. If the first substrate and the second substrate are both flexible substrates, and the above micro light emitting diodes are respectively disposed to the first substrate and the second substrate, thereby improving flexibility of the micro light emitting diode display device. If a reflection cup is disposed corresponding to the micro light emitting diodes, the brightness can be enhanced or the light emitting direction can be changed, thereby forming the micro light emitting diode display device capable of improving brightness and flexibility and increasing the resolution.

Description

technical field

[0001] The present invention relates to a display device, in particular to a micro light emitting diode display device. Background technique

[0002] Display devices made of organic light-emitting diodes (OLEDs) are actively replacing liquid crystal displays in the smartphone market. At the same time, another display technology, micro-light-emitting diode (Micro LED), is gradually being deployed, and has the opportunity to surpass organic light-emitting diodes, subvert the current display technology situation, and expand higher-level technology applications.

[0003] Micro-LED is an array structure of miniaturized light-emitting diodes, which has self-luminous display characteristics. With active components, each pixel can be individually addressed and driven to emit light. The advantages include high brightness, low power consumption, small size, and ultra-high resolution. Rate and color saturation etc. Micro-LEDs and organic light-emitting diodes are suit...
