The application discloses a reflective display device and a preparation method thereof, and relates to the technical field of display, wherein the reflective display device comprises a first substrate and a second substrate arranged oppositely, and at least two pixel areas are defined between the first substrate and the second substrate; the reflective display device further comprises cholesteric liquid crystals and fluorescent powders; the cholesteric liquid crystals comprise at least two kinds, the at least two kinds of cholesteric liquid crystals are arranged in the same layer and are respectively arranged in the at least two pixel areas; the fluorescent powders comprise at least two kinds, the at least two kinds of fluorescent powders can emit light of different colors and are respectively scattered in the at least two kinds of cholesteric liquid crystals arranged in the same layer. The reflective display device provided by the application can monitor whether the coating positions of the cholesteric liquid crystals reflecting different colors are in the suitable areas in the processing process.

The utility model relates to the technical field of surface coating machines, and specifically discloses a full-automatic surface coating machine for semiconductor sheet packaging with multi-station operation. It includes a frame base, and is characterized in that: a feeding area, a接驳对位区 (connection and alignment area), a coating area and a discharging area are provided on the frame base; a feeding transportation table is provided in the feeding area, an intermediate transportation table is provided in the connection and alignment area, a discharging transportation table is provided in the discharging area, and the intermediate transportation table moves back and forth along the Y-axis in the connection and alignment area and the coating area on the frame base by arranging a Y-axis driving component; a coating gantry is provided on the coating area of the frame base, a nozzle component is provided on the coating gantry, and the nozzle component moves along the X-axis and the Z-axis on the coating gantry by arranging an X-axis driving component and a Z-axis driving component; a visual positioning device is provided on the nozzle component. In the utility model, multi-station parallel operation processing can be carried out simultaneously in the feeding area, the coating area and the discharging area, so as to improve the production efficiency, and the combination of XYZ three-axis movement and the visual positioning device improves the coating accuracy. It should be noted that the term "接驳对位区" in the original text seems to be a Chinese term that may need to be further defined or replaced with a more standard English term if possible for better clarity in the translation. Here it is directly translated as "接驳对位区" for the purpose of following the translation rules strictly while waiting for possible improvement.

A kind of hollow toughened glass coating equipment, realize glass double side coating at the same time, avoid coating layer to be destroyed in the process of transfer, improve coating uniformity. Between left roller group and right roller group, there is smearing mechanism, smearing mechanism is connected with linear drive mechanism installed below middle roller group, middle roller group and left roller group and middle roller group and left roller group are equipped with two suction cup fixing assemblies, smearing mechanism includes upper and lower spaced upper paint box and lower paint box, one upper mounting plate is fixed on the both sides of upper paint box, upper drive mechanism is arranged on one end of upper paint roller and upper feed roller, one lower mounting plate is fixed on the both sides of lower paint box. Realize double side synchronous coating, improve production efficiency, avoid coating layer to be destroyed, improve coating quality, by setting middle roller group that can be up and down and suction cup fixing assembly around, glass is lifted by suction cup fixing assembly after coating is completed, can realize repeated coating.
