摘要： The present disclosure relates to an optical film configured on a top of a light guide plate. The optical film is made of quantum dot (QD) material, and the optical film is filled with a plurality of diffusion particles configured to uniformly distribute incident light toward different angles. As such, the backlight emitted from the backlight module may be uniform and may be emitted toward different angles, the color difference and the chromaticity of the display device from different viewing angles may be the same, and the performance of the display device may be improved.

摘要： The disclosure provides a backlight module includes a light guide plate and a light source device configured to provide light to the light guide plate. The light source device includes a circuit board and a LED lamp electrically connected to the circuit board. The LED lamp is external to the light guide plate and at a lateral surface of the light guide plate. The circuit board is parallel to the light guide plate with a portion pressed on another lateral surface of the light guide plate. The disclosure provides a display device includes a frame and a liquid crystal display screen and the backlight module installed on the frame. The reflective film and the circuit board share a part of room for thickness, so the thickness of the backlight module is reduced and the module is thinned.

摘要： The present disclosure discloses a liquid crystal panel, including a TFT substrate, a CF substrate, liquid crystal, and a first polarizer, wherein further includes a non-displayed binding end for connecting a COF, the first polarizer completely covers the TFT substrate, an encapsulant is disposed between the first polarizer and the binding end. The present disclosure further discloses a manufacturing method of the liquid crystal panel and a display device. In the liquid crystal panel and the manufacturing method thereof, by attaching a thermoplastic film on the binding end and the non-binding end and pressing the polarizer, the shadowing of the binding end can be realized in one step arid the side is encapsulated to simplify the process. And because of the process, just attached plastic mold, attached to the process of precision is not high, and without dispensing, greatly reducing production costs.

摘要： A surface finishing method, an anti-glare coating, and a display device having same are provided. The surface finishing method includes adding diffusion particles which have a density less than that of a resin material, and controlling the thickness of the resin material in an anti-glare material coated on a surface of a substrate to be greater than the particle size of the diffusion particles, so that the diffusion particles are evenly dispersed in the resin layer, and a part of the volume of the diffusion particles are exposed on a surface of the resin layer. Thus, the uniformity of the surface haze of the anti-glare coating can be enhanced, and flashing points of the display device can be avoided.
