Difference between positive display and negative display of LCD monochrome LCD screen

1. Positive display

The so-called positive display is that the color of the content displayed on the LCD screen is darker than the color of the background, such as: black characters on a yellow-green background (yellow-green screen) black characters on a gray-white background (FSTN), such screens generally display better in sunlight. There is also a relatively simple way to distinguish, that is, the color of most of the positive display characters is black. I just mentioned that this type of screen has a good display effect in the sun. It is precisely because the characters are black, so in the direct sunlight not easily affected under the conditions.

2. Negative display

The so-called negative display means that the color of the displayed content should be lighter than the background color, such as white text on a blue background (blue screen) and white text on a black background (VA segment code screen). Such screens have relatively high contrast, and the indoor display effect is better than positive.

There is also a relatively simple way of distinguishing, that is, the color of most of the negative display characters is white, because the LCD screen itself does not emit light, the color of the negative display words is actually the color printed by the backlight through the glass, and the backlight is white. The typed word is also white, in other words, the negative display must have a backlight to display the content.

At the same time, there is also a very common practice in negative display, that is, color screen printing. After adding screen printing, the LCD screen will become colorful and diverse. It can be said that because of this practice, the LCD screen will become more distinctive and innovative. In order to reflect the high-end effect, the method of negative display + color silk screen printing will be selected, which is also a product that is very worthwhile for everyone to choose.
