Abstract

The invention discloses an ultra-narrow structure of a backlight frame. The ultra-narrow structure comprises a diffusion silk-screen dot layer, a light absorption black adhesive tape, an LGP light guide layer, an LED light emitting source, a composite prism layer, a shading adhesive tape layer, a diffusion layer and a reflection light source layer. According to the invention, dot jet printing is carried out on the diffusion layer to improve the optical conduction capability, so that the distance from a point light source to an area light source is reduced from conventional 3.0-3.5mm to 1.0-1.5mm, the jaw of the liquid crystal display is correspondingly reduced, the display effect close to a full screen is achieved, and the visual enjoyment of a human body is improved; the structure is applied to a traditional LCD screen BLU, mature in technology and high in yield, the related performance of the LCD screen is still used while the narrow jaw is also achieved, the screen emits soft light,and the service life is long. Related performance of the LCD screen can be used while the narrow jaw is also achieved, so that the screen emits soft light, and the service life is longer.

Description

technical field [0001] The invention belongs to the field of module display, and in particular relates to an ultra-narrow frame structure of a backlight source. Background technique [0002] OLED, also known as organic electro-laser display, organic light-emitting semiconductor. OLED is a current-type organic light-emitting device, which is a phenomenon of luminescence caused by injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of an electric field in the OLED, the holes generated by the anode and the electrons generated by the cathode will move, inject into the hole transport layer and the electron transport layer respectively, and migrate to the light emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, which excite light-emitting molecules and finally produce visible light. [0003] Since the OLED screen is self-illuminating through pixels, when the scree...
