BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a light-emitting schematic diagram of a quantum dot high color gamut LED paper-like screen liquid crystal display module. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] As Figure 1 shown, the present utility model discloses a quantum dot high color gamut LED paper-like screen liquid crystal display module, which includes a quantum dot high color gamut LED 1, a first diffusion film 2, a brightness enhancement film 3, a second diffusion film 4, an LCD 5, a matte polarizer 6, and a nano-scale diffusive reflection module 7. The first diffusion film 2 is located above the blue LED 1, the brightness enhancement film 3 is located above the first diffusion film 2, the second diffusion film 4 is located above the brightness enhancement film 3, the LCD 5 is located above the second diffusion film 4, the matte polarizer 6 is located above the LCD 5, and the nano-scale diffusive reflection module 7 is located above the matte polarizer 6.
[0015] The nano-scale diffusive reflection module 7 is used to implement the nano-scale diffusive reflection technology, and the nano-scale diffusive reflection module 7 is an anti-glare cover plate.
[0016] LED is a prior art. An LED includes a transparent glue (generally epoxy resin glue), as well as a bracket, silver glue, gold wire, and an LED chip encapsulated inside the transparent glue. The present utility model improves the existing LED to form a quantum dot high color gamut LED 1. The quantum dot high color gamut LED 1 includes an LED and quantum dots, and the quantum dots are located inside the transparent glue of the LED.
[0017] As a preferred embodiment of the present utility model, the LED uses a low blue light LED chip. Because quantum dots are placed inside the transparent glue of the LED, the quantum dot high color gamut LED 1 can emit white light. The low blue light LED chip can emit blue light with a wavelength of 457.5 - 460 nm, so that the quantum dot high color gamut LED 1 can emit white light with a wavelength of 457.5 - 460 nm. The present utility model uses a low blue light LED chip, and the proportion of harmful blue light is about 30% (the TUV low blue light certification standard is less than 50%). The quantum dot high color gamut LED of the present utility model can significantly improve the proportion of harmful blue light.
[0018] In the light source layer of the present utility model, a quantum dot high color gamut LED1 is used as the backlight, so that the visual experience of the screen is not dazzling and the eye protection effect is achieved.
[0019] Compared with the existing paper-like screen, the present utility model replaces the white LED + diffusion film of the existing paper-like screen with a quantum dot high color gamut LED1 + a first diffusion film 2. The quantum dot high color gamut LED1 can reduce the harm of blue light and at the same time has the function of improving color saturation, thus improving the comfort of the human eye.
[0020] Compared with the existing quantum dot screen, the present utility model adopts a multi-layer anti-glare treatment. The dazzling light is atomized and scattered through multiple layers, reducing the irritation of the light to the eyes and playing an eye protection role. The multi-layer anti-glare treatment is realized by a first diffusion film 2, a second diffusion film 4, a matte polarizer 6 and a nano-level diffuse reflection module 7.
[0021] The present utility model combines a quantum dot high color gamut LED screen with a paper-like screen, which can improve the color saturation of the display screen and the eye protection effect of the paper-like screen. It can make the panel color gamut with a color saturation (NTSC) of 72% reach more than NTSC 100%, increase the vividness of the display, improve the comfort of the human eye, and can eliminate the problem of the blue edge phenomenon in the white picture that easily appears in narrow-edge products.
[0022] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
