Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an industrial semi-transmissive and semi-reflective TFT liquid crystal screen module. Background Art

[0002] As the performance requirements for display screens in industries such as industry, medical treatment, and fire protection continue to increase, the market demand for TFT LCD screens is also growing continuously. For example, in industrial field equipment and integrated workstations such as mining and oil field testing, or in the field of medical devices, especially in situations where lighting environments are required, such as surgery and emergency, high requirements are placed on the contrast, resolution, and viewing angle of the display screen.

[0003] The existing TFT liquid crystal display refers to a thin film transistor, that is, each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that high speed, high brightness and high contrast can be achieved. It is one of the best LCD color display devices at present. Each pixel of TFT is controlled by the TFT integrated on itself, which is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness are greatly improved. At the same time, the resolution has also reached a very high level. However, the TFT liquid crystal display will show strong reflection on the LCD screen under strong light, affecting the viewing of the picture on the LCD screen. It is especially inconvenient to use it on outdoor industrial equipment used in direct sunlight. Utility Model Content
