Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Since the display substrate of the existing Micro-LED display needs to install three LED chips on the backplane to form a pixel unit, the workload of the mass transfer of the Micro-LED display is large, and the display circuit layout is complicated.

[0041] In order to solve the above problems, Embodiment 1 of the present invention provides a display substrate, such as Figure 4 As shown, the display substrate includes a backplane 1 and a plurality of pixel units 2 . Wherein, the pixel unit 2 includes a white light LED 21 arranged on the back plate 1 for emitting a white light b...

Abstract

The invention provides a display substrate and a display device. The display substrate comprises a back plate and a plurality of pixel units, and each pixel unit comprises a white light LED arranged on the back plate and used for emitting a white light beam, a collimating lens used for collimating the white light beam, a prism layer used for reflecting the white light beam to generate monochromatic light with different colors, a transmittance controller used for modulating monochromatic light of different colors, and a scattering layer used for scattering light beams emitted by the transmittance controller. The prism layer reflects the white light beam to obtain monochromatic light of different colors; the single-color light of different colors is modulated through the transmittance controller to generate the colors corresponding to the pixel units, so that only one LED chip needs to be mounted on the back plate corresponding to one or more pixel units, and the huge transfer workload of the display and the circuit arrangement complexity of the display are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of semiconductor optoelectronics, and in particular relates to a display substrate and a display device. Background technique [0002] Micro light emitting diode (Micro light emitting diode, Micro-LED) display has good stability, lifespan, and advantages in operating temperature, and also inherits LED low power consumption, color saturation, fast response, and strong contrast And other advantages, the brightness of Micro-LED is higher, and the power consumption is lower, which makes Micro-LED display have great application prospects. [0003] The structure diagram of the display substrate of the current Micro-LED display is as follows: figure 1 and figure 2 As shown, the display substrate of the existing Micro-LED display is composed of a backplane and a plurality of pixel units arranged on the backplane, and each pixel unit includes red LEDs, green LEDs and blue LEDs arranged in sequence. In order to sa...
