Abstract: Disclosed are a manufacturing method of an anti glare layer and a display panel. The method comprises: preparing a spray solution comprising sprayed particles, each having a shell structure; spraying the spray solution uniformly onto the glass substrate by a spraying device to form an arrangement structure on the glass substrate; spraying an acidic liquid on the arrangement structure to remove the shell structures of the sprayed particles each having the shell structure to form gaps among the spray particles; implementing an annealing treatment to the sprayed particles to form the anti glare layer. Thus, the light diffraction effect can be reduce or even eliminated to improve the picture quality of the display for promoting the comfort of the user viewing.

Abstract: The present disclosure discloses a backlight module and a display device. The light emission direction of at least one of the lamp source and the fluorescent film is provided with a diffusely reflecting layer. The diffusely reflecting layer arranged above the lamp source diffusely reflects pump light emitted from the lamp source, which may enhance uniformity of the pump light. The diffusely reflecting layer arranged above the fluorescent film scatters light emitted from the fluorescent film, scatters the light and distributes the light to a larger range, which may improve light mixing uniformity and improve the uniformity of light emission brightness.

Abstract: The present invention provides a processing method of a cover plate, a control apparatus, a cover plate processing apparatus, and a storage medium. The processing method utilizes a scanning device to scan surfaces and obtain surface features of a first cover plate and a second cover plate, and performs Fourier transformation on the surface features of the first cover plate and the second cover plate to obtain the surface feature frequency variation distribution curves of the first cover plate and the second cover plate, thereby to obtain the surface feature frequency variation distribution curves of a high-resolution cover plate. Fourier inverse transformation is performed on the surface feature frequency variation distribution curves of the high-resolution cover plate to obtain surface features of a target cover plate, so that the high-resolution cover plate so processed meets balancing speckles and anti-glare requirements.
