However, the inventors found that LCD display panels are difficult to produce flexible, high-color-gamut display panels, and have high power consumption; OLED display panels are difficult to produce high-resolution, high-transmittance display panels and have limited luminous life.
[0004] Inorganic light-emitting diode (miro-OLED) has the advantages of high transmittance, light and thin, low power consumption, high color gamut, etc., and an inorganic light-emitting diode display panel has emerged as the times require, but this display in the prior art The panel is not adjustable, and the requirements for people are getting higher and higher, so an inorganic light-emitting diode display panel with adjustable viewing angle is a technical problem that needs to be solved urgently

Embodiment 1
[0024] Such as figure 1 As shown, this embodiment provides a display panel, including a display substrate and a liquid crystal lens arranged on the light-emitting surface side of the display substrate; wherein, the display substrate includes: a first substrate 1, a plurality of pixel units arranged on the first substrate 1 10. Each pixel unit 10 includes an inorganic light emitting diode 11; the liquid crystal lens includes a plurality of lens units 20, and the lens units 20 are arranged corresponding to the pixel unit 10 for adjusting the light emitting direction of the inorganic light emitting diode 11 in the pixel unit 10.
[0025] Since the inorganic light-emitting diode 11 has the advantages of small size, high brightness, high contrast, light and thin, low power consumption, high color gamut, high efficiency, long life, fast response, etc., in this embodiment, the inorganic light-emitting diode will be transferred by printing. The light emitting diode 11 is applied to th...
Embodiment 2
[0037] This embodiment provides a display device, which includes the display panel in Embodiment 1. Therefore, the display device has the advantages of high resolution, flexibility & transparency, high brightness, high contrast, light and thin, low power consumption, high color gamut, and the like.
[0038] Wherein, the display device can be a liquid crystal display device or an electroluminescence display device, such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a TV set, a monitor, a notebook computer, a digital photo frame, a navigator, etc. product or part.

Abstract
The invention provides a display panel and a display device, belonging to the field of display technology. The display panel of the present invention includes a display substrate and a liquid crystal lens arranged on the light-emitting surface side of the display substrate; wherein, the display substrate includes: a first substrate, a plurality of pixel units arranged on the first substrate; each pixel unit includes an inorganic The light-emitting diode; the liquid crystal lens includes a plurality of lens units, and the lens units are arranged corresponding to the pixel units, and are used to adjust the light emitting direction of the inorganic light-emitting diodes in the pixel units. Since inorganic light-emitting diodes have the advantages of small size, high brightness, high contrast, light and thin, low power consumption, high color gamut, high efficiency, long life, and fast response, the display substrate has high resolution and good display effects. At the same time, since the light emitting surface side of the display substrate of the present invention is also provided with a lens unit for adjusting the light emitting direction of the inorganic light emitting diode in the pixel unit, the display panel can realize display of different viewing angles.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] With the development of flat panel display technology, the performance requirements of the display panel are getting higher and higher. High resolution, flexibility & transparency, high brightness, high contrast, light and thin, low power consumption, high color gamut, etc. have become the development direction of display panels. [0003] Currently commonly used flat panel display devices include a Liquid Crystal Display (LCD for short) and an OLED (Organic Light-Emitting Diode: Organic Light-Emitting Diode) display device. However, the inventors found that LCD display panels are difficult to produce flexible, high-color-gamut display panels, and consume high power; OLED display panels are difficult to produce high-resolution, high-transmittance display panels and have limited luminous life. [000...
