The array substrate includes a plurality of GOA units in cascade and a plurality of clock signal lines. The plurality of clock signal lines are arranged on one side of the GOA units and are arranged at intervals along a direction away from the GOA units. The plurality of GOA units are electrically connected to the plurality of clock signal lines, respectively. Wherein, a number of the GOA units electrically connected to each of the clock signal lines is equal.

Abstract: The present application discloses a color resist material, a filter, and a preparation method thereof. The color resist material is a trimer structure formed by polymerizing phthalocyanine dyes, wherein groups with double bonds are introduced on the phthalocyanine dyes to construct a three-molecule complex by a complexing agent, and the phthalocyanine dyes are connected by the double bonds to form a trimer structure. The color resist material with the trimer structure is stably stored in a photoresist liquid and has excellent solvent resistance, while maintains good solubility. Accordingly, a filter made of the color resist material has high transmittance and good optical performance.

Abstract: A mini-LED backlight structure and a backlight module are provided. The mini-LED backlight structure includes a backplate, a glass substrate, and reflective sheets. The glass substrate includes a line surface and a lineless surface close to a side of the backplate. Light emitting diodes and a connector are disposed on the lineless surface. Furthermore, a gap is between the backplate and the glass substrate for disposing the light emitting diodes and the connector. The connector is electrically connected to an external circuit through a conducting wire. Disposing a plurality of elements, the connector, and the light emitting diodes on a same surface of the lineless surface is unlikely affecting backlight effect and saves materials at a same time.

Abstract: A display device driving method and the display device are provided. The display device driving method determines a driving voltage value of each backlight unit based on a content to be displayed by a display unit corresponding to each backlight unit, achieving dynamic adjustment of luminous brightness of the backlight unit according to the display content of the corresponding display unit. Meanwhile, the driving voltage value is related to a noise in an image. Therefore, a better backlight brightness value can be obtained by reducing an influence of the noise on the adjustment of the luminous brightness.
