When we take the elevator, we will find that when it comes to the choice of display screen, although there are many differences in elevator brands now, most elevators still choose dot matrix LCD screens as the carrier of floor display. So, there are many types of display screens now, why are dot matrix LCD screens frequently used in elevator floors. First of all, we need to understand the advantages of this LCD screen.
Generally speaking, the dot matrix LCD screen itself is composed of small pixels arranged in a familiar array manner. One of the biggest advantages of this array arrangement is that it does not affect each other. When one of the pixels is damaged due to human factors or circuit board reasons, only the position of this pixel will not light up or not display, without affecting the function of the entire LCD screen.
At the same time, the performance of the dot matrix LCD device is very stable, and the digital display effect is remarkable. It can display a variety of information, including the current floor, destination floor, operating status, fault prompts, etc., providing richer information. In addition, it has a long service life. This kind of LCD screen consumes less energy than traditional LED displays and is more energy-saving when used for a long time. It is generally difficult to cause major problems during use.
Therefore, it is better to choose dot matrix LCD Screens are also mostly considered for the overall safety and convenient maintenance of the elevator. Because dot matrix LCD screens generally have good durability and anti-interference capabilities, they are suitable for use in environments such as elevators. Once there is a problem with any pixel, it is convenient. Perform maintenance. However, one thing that needs to be noted here is that the display must be maintained and repaired regularly, because once there is a problem with the pixels, it may affect the reading of the floor display numbers, affect the passenger’s ride, and may also cause problems due to the pixels.
The damage to the matrix pixels affects the monitoring end of the floor status. Therefore, when a problem is found with the elevator’s dot matrix LCD screen, it must be maintained or replaced as soon as possible.
