Should segment display screens be backlit? How to add it? [Copy link]

        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 needs backlight depends on the product and customer usage; for example, most air conditioner remote controls on the market do not have backlights, because they are only used when there are lights in the room. Few people will use them when turning off the lights at night to sleep. If there is a backlight, they will get used to sleeping. Another is the cost issue. This kind of product is cheap and pursues low cost, so basically no backlight is added, such as calculators.

Of course, if your product needs to be visible even when there is no light, such as at night, or in basements and other places, then a backlight is needed. So how to add a backlight? Normally, the general LCD screen factory will provide you with matching products. What we need to decide is how many lights to add, what color lights, thickness and other issues. The number of lights depends on the size of our screen. If the negative display screen is of the same size, installing two more lights will have a better effect. There are many colors of LED lights, which can be selected according to the needs of the product. The thickness issue mainly depends on whether there is enough space for your product content.
