Embodiment 1

[0036] see figure 2 The Micro LED display device provided in Embodiment 1 of the present application includes: a driving substrate 11 and a packaging substrate 12 that are arranged oppositely. 12 is provided with a color pixel layer on one side, and the color pixel layer includes a red sub-pixel unit 14-1, a green sub-pixel unit 14-2 and a blue sub-pixel unit 14-3, and a plurality of blue Micro LEDs 13 arranged on the color pixel layer The first blue light Fabry-Perot (FP) light-transmitting layer 15 that only allows blue light to pass through on one side.

[0037] Wherein, the above-mentioned Micro LED display device can be any product or component with a display function such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0038]The above-mentioned driving substrate 11 can be, for example, a glass substrate with a control circuit for controlling the blue Micro LED13; it can also be a th...

Embodiment 2

[0060] Normally, when blue light passes through the color pixel layer, it cannot be converted 100% (for example, when blue light passes through the red quantum dot layer of the red sub-pixel, it cannot be completely converted into red light), so that part of the blue light passes through the color pixel layer. , leading to blue leakage problems.

[0061] In order to solve this problem, the Micro LED display device provided in Embodiment 2 of the present application is improved on the Micro LED display device provided in Embodiment 1 of the present application.

[0062] The Micro LED display device provided in Embodiment 2 of the present application is similar to the Micro LED display device provided in Embodiment 1 of the present application, and the same parts will not be repeated here, and only the different parts will be described below.

[0063] Such as Figure 5 As shown, the Micro LED display device provided in Embodiment 2 of the present application also includes: a pl...

Abstract

The present application provides a Micro LED display device to reduce color crosstalk between pixels. The Micro LED display device provided in the present application includes: a driving substrate and a packaging substrate oppositely arranged, and the driving substrate faces the packaging substrate A plurality of blue Micro LEDs arranged in an array are arranged on one side of the packaging substrate, and a color pixel layer is arranged on one side of the packaging substrate, and the color pixel layer includes a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit, It also includes: a first blue FP light-transmitting layer that is provided on the side of the color pixel layer facing the plurality of blue Micro LEDs and only allows blue light to pass through.

Description

technical field [0001] The present application relates to the technical field of Micro LED display, and in particular to a Micro LED display device. Background technique [0002] Micro LED (Micro LED) is a new generation of display technology with self-luminous display characteristics. Compared with the existing Organic Light-Emitting Diode (OLED) technology, Micro LED display device has higher brightness and luminous efficiency. Advantages of better and lower power consumption. [0003] Currently, see figure 1 A color display Micro LED display device generally includes: a driving substrate 11 and a packaging substrate 12 arranged opposite to each other. On the side of the driving substrate 11 facing the packaging substrate 12, there are a plurality of blue Micro LEDs 13 arranged in an array (each of the Micro LED display device One sub-pixel corresponds to a blue light Micro LED), and one side of the packaging substrate 12 is provided with a color pixel layer; the color p...
