The touch display panel includes a color filter substrate, an array substrate arranged opposite to the color filter substrate, and a liquid crystal layer arranged between the color filter substrate and the array substrate. Black matrices are arranged on the color filter substrate. A plurality of first electrodes made of metal is arranged parallel to each other on the color filter substrate, and a projection of each first electrode onto the color filter substrate in a perpendicular direction completely falls within a range of a corresponding black matrix. A plurality of second electrodes made of a transparent conductive layer is further arranged parallel to each other on the color filter substrate, and the second electrodes are insulated from, and cross, the first electrodes.

Touch display panel and touch display device

Provided are method for manufacturing a color filter substrate, color filter substrate and display device. The method includes the following steps: providing a substrate; forming a color pixel unit on the substrate; forming a protective layer on the color pixel unit; coating an alignment film paint and a spacer paint on the protective layer in turn, and forming an alignment film and a spacer via a single patterning process or double patterning processes.

Method for manufacturing color filter substrate, color filter substrate and display device

The present disclosure provides a developing device and method. The developing device includes the nozzle for spraying the developing liquid, the machine table for bearing the glass substrate, and the inclination controller for controlling the nozzle and the machine table to be inclined towards a predetermined direction of the machine table at a predetermined angle and keeping the inclined angle within a preset period. The method includes controlling, by the inclination controller, the machine table and the nozzle to be inclined towards a first direction of the machine table at a predetermined angle during the inclination cycle period and keeping the inclined angle within the preset period, and controlling, by the inclination controller, the machine table and the nozzle to be sequentially inclined towards other directions of the machine table at a predetermined angle according to the preset inclination direction sequence and keeping the inclined angle within the preset period.

Developing device and developing method

Embodiments of the disclosure provide an exposure method and an exposure device. The exposure method comprises: placing at least two transparent substrates coated with photoresist under one mask, wherein all of the at least two substrates are in parallel with the mask; irradiating the mask vertically with parallel exposure light to respectively expose the photoresist on the at least two substrates along a propagation direction of the exposure light.

Exposure method and exposure device

An embodiment of the present invention provides a fly eye lens which is applied to a proximity exposure machine optical system. The fly lens includes a first lens assembly and a second lens assembly, wherein the first lens assembly includes a plurality of lenses which form a first lens face, and the second lens assembly includes a plurality of lenses which form a second lens face. The first lens face is used to split an incident broad light beam into narrow light beams and then refract the narrow light beams onto the second lens face, and the second lens face is used to dispersively refract the received narrow light beams onto a concave mirror in the optical system. A lens closer to a center of the second lens face has a higher transmittivity, and a lens farther from the center of the second lens face has a lower transmittivity. According to the embodiment of the present invention, since different lenses on the second lens face have different transmittivities, the illuminances of light radiated to different regions of a mask plate through the fly eye lens are different, and thus the uniformity of the critical dimensions of the exposed patterns can be improved to a certain extent.
