LCD monochrome LCD screens usually have positive and negative display types. We will take the segment code screen as an example today, the following LCD screen is a small series to introduce the difference between the two display types: first, positive display: the so-called positive display is that the color of the content displayed on the LCD screen is deeper than the color of the background, for example: yellow and green black characters (Yellow green screen)Black and White (FSTN) Such screens generally display better in the sun. The bottom is gray-white/green, the word is black, and the color of the word is deeper than the background color, which is positive; There is also a relatively simple way to distinguish, that is, most of the colors of the positive characters are black characters. Just now, it was said that such screens have a good display effect in the sun, and it is precisely because the characters are black, therefore, it is not easily affected under direct sunlight. Second, negative display: the so-called negative display means that the color of the displayed content is lighter than the background color, such as blue and white characters (Blue Screen), Black and white screen (VA segment code screen) This kind of screen has relatively high contrast, and the indoor display effect is better than the positive display. The bottom is black/blue, the word is white, and the color of the word is lighter than the background color, which is negative; There is also a relatively simple way to distinguish, that is, the color of most negative words is white, because the LCD screen itself is not luminous, the color of the negative display word is actually the color of the backlight through the glass, and the word of the backlight white is 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 of negative display, that is, color silk screen printing, and the LCD screen after silk screen printing will become colorful and diverse. Please see: the above is the difference between positive and negative display of LCD monochrome LCD screen brought to everyone by the small LCD screen. I hope I can give you more understanding.
