Liquid Crystal Displays (LCDs) have the characteristics of small size, low power consumption, no radiation and the like, and now occupy the leading position in the field of flat panel displays. Thin Film Transistor-Liquid Crystal displays (TFT-LCDs) are currently the mainstream Liquid Crystal displays and are widely used in electronic devices such as high definition digital televisions, desktop computers, Personal Digital Assistants (PDAs), notebook computers, mobile phones, digital cameras, and the like. The liquid crystal panel comprises an Array substrate (Array), a color film substrate (CF) and frame sealing glue for bonding the Array substrate and the color film substrate. The color substrate (CF) comprises a glass substrate, a black matrix, a red-green-blue (RGB) color layer, a protective layer and an indium-tin oxide transparent conductive film layer. The black matrix is located at the interval of R color resistance, G color resistance and B color resistance of the RGB color layer, and has a certain overlap at the contact part.
The lcd panel can only control the brightness of Light passing through the lcd panel, and has no Light Emitting function, so that a backlight source such as an LED (Light Emitting Diode) and an LGP (Light Guide panel) is required to provide high brightness and uniform Light distribution required for displaying images. At present, a side-light LED backlight is generally adopted, that is, LED dies are disposed at least one side edge of a liquid crystal display panel, and then, the use of an LGP is used, so that when the LED backlight module emits light, the light emitted from the edge of the liquid crystal display panel is transmitted to the whole area of the liquid crystal display panel through the LGP, thereby enabling the liquid crystal display panel to normally display images.
As the size of the mobile phone liquid crystal display screen is increased, PPI is increased and the transmittance is obviously reduced. And the precision of laminating equipment has greatly influenced the transmissivity of display screen. In the conventional LCD process, the BM light-shielding layer is formed on the CF glass. The expansion rates of Array glass and CF glass are different, the larger the size of the glass substrate is, the larger the alignment deviation caused by different glass expansion is, the larger the Array pattern shields the BM opening area, the lower the opening rate is caused, and the lower the transmittance is caused. Meanwhile, the existing liquid crystal display screen arranges the shading layer at the CF side, and the liquid crystal layer is arranged in the middle, so that the capacitance loading is increased to a certain extent.
