The invention discloses a substrate, a mask plate and a liquid crystal display device, relates to the field of liquid crystal display and solves the problem that since a color film substrate is short of large amount of redundant PS, the thickness of a liquid crystal box by closing the color film substrate and array substrate is uneven. According to an embodiment, the substrate comprises panel regions provided with a plurality of rectangles arrayed in the horizontal and vertical directions, and each panel region is used for manufacturing one color film substrate; the panel region comprises four first alignment modules located at four corners of the panel region; the adjacent corners of two adjacent panel regions share one alignment module in the horizontal and vertical directions; the first alignment modules are located in the mask redundant region outside the panel redundant region. According to the embodiment, the invention further provided a liquid crystal display device and a mask plate used for forming patterns on the substrate.

Substrate, mask plate and liquid crystal display device

The invention provides an array substrate mother plate and a manufacturing method therefor, and a mask plate. The mask plate is provided with at least one first exposure region; each first exposure region corresponds to one array substrate on the array substrate mother plate; the mask plate is further provided with a second exposure region; and the second exposure region is used for forming identification codes of the array substrates on the array substrate mother plate. The mask plate provided by the invention, by adding the second exposure region for manufacturing the identification codes on the mask plate, enables the identification code manufacturing process on the array substrate mother plate and the production process of the array substrates to be performed at the same time, so that the manufacturing time of the array substrate mother plate is greatly reduced and the production efficiency is improved.

Array substrate mother plate and manufacturing method therefor, and mask plate

An exposure machine having a code printing function is disclosed. The exposure machine comprises an exposure system including a light source, a mash, an objective, a substrate and a workpieces stage. The exposure machine is characterized in that the exposure machine also comprises a code printing system, the code printing system comprises a light source, a code printing system fixing module, a liquid crystal digital display module, a code printing position adjusting module and a coding and positioning software module, and the code printing system and the exposure system work simultaneously. The exposure machine can print a code onto an edge screen of each exposure field at the same time of exposure, thus significantly shortening production time for subsequent titlers, and increasing the productivity of a whole production line without equipment configuration changes of the production line.

An exposure machine having a code printing function

The invention discloses a display panel and a manufacturing method thereof. The display panel includes: a display area and a non-display area; the display area is arranged in the center of the whole display panel; the non-display area is arranged on the periphery of the display area and an identification code pattern is further arranged on one of the sides of the non-display area; and the identification code pattern is produced by using exposure with an exposure machine and then by using dotting with a coding machine, and the identification code pattern is a regular graph. The beneficial effect is as follows: firstly, the identification code pattern is arranged inside the non-display area of the display panel provided by the application, and the identification code pattern is a regular graph and produced by using the exposure with the exposure machine and then by using the dotting with the coding machine without the need for adding a new machine or changing a production process, thus the coding time is shortened and the production cycle is reduced; and secondly, since the identification code pattern is produced by using the exposure with the exposure machine and then by using the dotting with the coding machine, the exposure accuracy of the exposure machine can reach 3 [mu]m, which greatly reduces the size of the identification code pattern and is beneficial for realizing a narrow frame.

Display panel and manufacturing method thereof

The present invention discloses a method for marking a substrate, wherein in a picture composition process of a substrate, a mask with a marking pattern is adopted to expose the substrate, and the mark corresponding to the marking pattern is formed on the substrate According to the present invention, the exposure process is adopted to directly achieve marking, and the panel area ID is assigned to the panel area on the substrate when the exposure process is performed so as to eliminate the marking machine marking time, such that the production time is easily shortened, and the productivity is easily increased
