Description

Technical Field

[0001] This utility model relates to the field of quantum rod panel technology, specifically a novel quantum rod panel structure. Background Technology

[0002] Currently, most smartphones and tablets emit harmful blue light due to the use of phosphor backlights. These backlights consist of two parts: yellow light from phosphors and blue light from LEDs. Because phosphors have a low efficiency in converting blue light to yellow light, the blue light portion accounts for more than 60% or even more of the yellow-blue light ratio in phosphor backlights. Furthermore, phosphor backlights are excited by 450nm LED light sources, and this wavelength of blue light is the most harmful to the human eye. When using smartphones and tablets, this light source can damage the retina.

[0003] To address the blue light hazards of phosphor light sources, some products use blue filters to filter the blue light emitted by the light source. However, due to the lack of blue light, the color rendering quality and color temperature (the color of white light) will drop rapidly. In addition, some products use software to deal with image flickering issues, but this does not reduce the harmful blue light emitted by the light source. Utility Model Content

[0004] The purpose of this invention is to provide a novel quantum rod panel structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel quantum rod panel structure, comprising a hybrid backlight, a quantum rod light-emitting layer bonded to the hybrid backlight, a TFT array layer bonded to the quantum rod light-emitting layer, a liquid crystal layer bonded to the TFT array layer, a filter bonded to the liquid crystal layer, a polarizer bonded to the filter, and a glass substrate bonded to the polarizer.

[0006] Furthermore, the hybrid backlight, quantum rod light-emitting layer, TFT array layer, liquid crystal layer, filter, polarizer and glass substrate are bonded together with transparent optical adhesive and sealed at the edges to prevent oxidation.

[0007] Furthermore, the optical path is transmitted from bottom to top through the hybrid backlight, quantum rod light-emitting layer, TFT array layer, liquid crystal layer, filter, and finally polarizer output.

[0008] Furthermore, the hybrid backlight source includes ultraviolet LEDs and blue LEDs, and the quantum rod light-emitting layer includes green QR light that can be excited by ultraviolet LED light source and red QR light that can be excited by blue LED light source.

[0009] Furthermore, the TFT array layer is composed of low-temperature polycrystalline silicon thin-film transistors and an ITP pixel electrode matrix, and the liquid crystal layer rotates the polarization direction of the light under an electric field.

[0010] Furthermore, the filter retains only red and green colors, and the blue light channel in the filter is open.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses both ultraviolet LEDs and blue LEDs in a hybrid backlight, and green QR light that can be excited by ultraviolet LEDs and red QR light that can be excited by blue LEDs in the quantum rod light-emitting layer. By adding an extra pure blue LED, combined with the green and red QR materials, this combination can provide high-purity, high-efficiency red and green light peaks and harmless blue light emission. In this way, we can achieve a high-color-performance eye-protection display and reduce blue light hazards by using a special combination of QR LEDs without any blue filter and improving the software of the LCD display.
