摘要： A backlight includes a plurality of light sources of at least three different colors disposed on a base substrate, and a plurality of grating units that are disposed on a light exit side of the plurality of light sources and are in one-to-one correspondence with the plurality of light sources. Each of the plurality of grating units is used for splitting light emitted by a corresponding one of the plurality of light sources to form in an array of uniformly distributed monochromatic spots, so that the backlight may form an array of colored spots in which at least three different colors of light spots are alternately arranged in sequence along a first direction, wherein the first direction is a row direction or a column direction of the array of colored spots.

摘要： A backlight module comprises a light source, a light guide plate and at least one transparent light guide structure. Each transparent light guide structure comprises a first surface adjacent to a side of the light guide plate and a second surface far away from the light guide plate, a light emitted by the light source is directed into the first surface of the transparent light guide structure through the light guide plate. Each transparent light guide structure is configured to change a propagation direction of a first light in the light emitted by the light source, so that an emergence angle of the first light emitted from the second surface is smaller than an incidence angle of the first light incident from the first surface. The incidence angle of the first light onto the first surface is less than 90 degrees.

摘要： A shift register, a gate driving circuit, and a display device, the shit register includes an input module, a first reset module, a first control module, a second control module), a node voltage control module, and an output module. With cooperation of the aforesaid six modules and by setting the node voltage control module to form a bootstrap circuit together with the second control module, the shift register can make a voltage at the second node equal to a voltage of the effective pulse signal at the first clock signal terminal, so that the first control module can operate promptly and effectively under control of the second node.

摘要： A backlight and a liquid crystal module having the same are provided. The backlight comprises: a light guide plate, a light-guide-plate fixing element for fixing the light guide plate, and at least one light source disposed adjacent to the light guide plate, wherein the light-guide-plate fixing element is made of thermal-contractive material. As the light-guide-plate fixing element is made of thermal-contractive material, in a test environment of high temperature and high humidity, it is possible to ensure that the light guide plate can expand and contract freely without resistance; meanwhile; while at normal temperatures, as the tight-guide-plate fixing element is in contact with the light guide plate without gap therebetween.
