The invention discloses an anti-reflection stacked structure and a manufacture method, a substrate and a display device thereof and belongs to the field of display devices. The anti-reflection stacked structure comprises multiple light absorption layers which are arranged in a stacked mode, and the content of non-metallic elements in the two or more light absorption layers of the multiple light absorption layers is different. The anti-reflection stacked structure is composed of the multiple light absorption layers, the light absorption layers can absorb ambient light and lower the reflection to the ambient light by the anti-reflection stacked structure, when the anti-reflection stacked structure is applied in the display device and used for blocking out the substrate, it can be avoided that reflected light increases the pure black brightness of a screen, the contrast ratio equals to the pure white brightness divided by the pure black brightness, and therefore the decrease of reflectance can increase the display contrast, so that the quality of pictures is guaranteed.

A method of producing microcapsules having an electrophoretic particle dispersion encapsulated comprises the steps of: emulsifying and dispersing a hydrophobic dispersion having electrophoretic particles dispersed in a hydrophobic medium by using a high-speed rotating stirring apparatus wherein the circumferential speed at the end of a stirring part is 2 m / s to 90 m / s, and the distance (a) between the end of the stirring part and that immobile part of the stirring apparatus which is nearest to the end of the stirring part is 0 mm<(a)<20 mm; and forming microcapsules of the emulsified and dispersed hydrophobic dispersion under stirring with a stirring blade.

A hard-coated antiglare film that has excellent antiglare properties, prevents a glare phenomenon from occurring, and prevents white blur from occurring to have excellent display contrast in bright light. The hard-coated antiglare film includes a transparent plastic film substrate and a hard-coating antiglare layer containing fine particles. The hard-coating antiglare layer is formed on at least one surface of the transparent plastic film substrate. The hard-coating antiglare layer has a surface with an uneven structure. The hard-coated antiglare film has a total haze value ht in the range of 40 to 70%. The relationship between the total haze value ht and an inner haze value hi obtained due to scattering inside the hard-coating antiglare layer is a relationship of the total haze value ht≦the inner haze value hi.

The invention provides a pixel structure for a displaying device and the displaying device, wherein the pixel structure uses a light entering from the outside of the displaying device as a light source. The pixel structure comprises a first substrate, a light barrier layer, an active element and a moveable light shielding layer, wherein the light barrier layer is arranged on the first substrate and provided with a transparent area and a lightproof area; the active element is arranged in the lightproof area of the light barrier layer and has a first state and a second state; and the moveable light shielding layer is arranged on the light barrier layer and the active element. When the active element is in the first state, the moveable light shielding layer properly shields the transparent area so as to prevent the light from emitting out from the first substrate; and when the active element is in the second state, the moveable light shielding layer is driven to allow the light ray to passes through the transparent area and to be projected out from the first substrate.

A display device includes a light guide plate which includes a light transmission portion and an antireflection portion at two opposite end faces and which is provided with a light extraction portion in part of a surface, respective light sources which are arranged on outer sides of the two opposite end faces, a transmission liquid crystal panel located adjacent to the light extraction portion, and a synchronous drive unit that alternately turns ON the light sources and that displays an image that is synchronous with an alternating turn-ON operation of the transmission liquid crystal panel.

An apparatus of driving the liquid crystal display of the present invention includes a picture quality improving unit that receives input data for a frame, wherein the picture quality improving unit analyzes green input data to determine a brightness of the frame and performs a gamma compensation on the input data in accordance with the brightness of the frame to generate output data; and a timing controller that rearranges the output data to supply the rearranged output data to the data driver.

The invention relates to the field of LED (Light-Emitting Diode) packaging, in particular to an LED display screen. The LED display screen comprises a lamp panel and LED lamp beads arranged on the lamp panel, wherein light absorption face masks are arranged on the lamp panel and are positioned among the LED lamp beads; the widths of the light absorption face masks are gradually reduced from the ends in contact with the lamp panel to the opposite ends. The light absorption face masks are arranged among the LED lamp beads for absorbing external light, so that external stray light is reduced, and the display contrast ratio is promoted; meanwhile, the structures of the light absorption face masks are improved, so that the widths, at the ends in contact with the lamp panel, of the light absorption face masks are greater than those at the other ends opposite to the ends in contact with the lamp panel, the widths, at the ends far away from the lamp panel, of the light absorption face masks are arranged in a reduced mode, the absorption and blocking of light absorption walls of the light absorption face masks for red, green and blue light rays in the LED lamp beads are reduced, the visual angle of the display screen is enlarged, and the visual color difference is eliminated as much as possible. Meanwhile, the using material of the light absorption face masks is further reduced, and the product cost is reduced.
