Should the segment code display be backlit? How to add?

Under the premise of how to add backlight to the segment code screen, let's first understand whether the segment code LCD screen needs to be backlit?

Whether the segment code LCD screen should be backlit or not depends on the product and customer usage; for example, the air conditioner remote control, most of them on the market do not have a backlight, because it is only used when there are lights in the room, and the lights are turned off at night. When sleeping, few people use it. If there is a backlight, they will get used to sleeping. Another issue is the cost. This product is inherently cheap and pursues low cost, so basically no backlight is added, such as a calculator.

Of course, if your product needs to be seen clearly when there is no light, such as at night, or in the basement, you need to add backlight at this time. So how to add backlight? Normally, the LCD screen factory will make it for you. What we need to decide is how many lights to add, what color lights, thickness and other issues.

The number of lights is determined according to the size of our screen. If you install 2 more negative display lights of the same size, the effect will be better. There are many kinds of LED lights in color, which can be selected according to the needs of the product. Thickness: mainly depends on you Not enough space for product .
