An LCD display module is a very small but highly complex component that can independently display information. It is an essential and major part of LED screens, applicable to most LED screen products on the market. We all know that without equipment to input video signals through a video cable, an LCD screen will not display video information. An LCD module is a device that integrates the signal output equipment, video cables, and the LCD screen.
An LCD display module refers to a modular component that is assembled from parts such as an LCD panel, driver circuit, backlight, and integrated circuit. Its structure varies depending on the application of downstream products, but the differences are not significant.
The working temperature for a normal-temperature LCD is 0℃~50℃, and the storage temperature is -20℃～70℃. For wide-temperature LCDs, the working temperature is -30℃～80℃, and the storage temperature is -40℃～100℃. At normal temperature, the threshold voltage for TN is as low as 0.7V and for STN it's as low as 0.8V. The lower threshold voltage will correspondingly increase at wide-temperatures.
An LCD display module is a component that assembles LCD devices, connectors, integrated circuits, PCB circuit boards, backlights, and structural parts together. In practice, it is a commercialized component. Although its application is already widespread, many still find it challenging to use and assemble. Especially with dot-matrix LCD devices, users often find it overwhelming. The special connection methods and necessary specialized equipment are not commonly known or available to everyone. Therefore, users of LCD devices hope for assistance in assembling the LCD devices with the control and driver integrated circuits into a functional component, allowing users to assemble it into a complete system using traditional techniques.
