What is the definition of Negative LCD display?

LCD Definition

The LCD, or liquid crystal display, is a type of display technology that uses crystals to control the level of light passing through it. This makes it possible to create images on a screen that can be seen in a wide range of lighting conditions, from full sunlight to complete darkness. LCDs are used in everything from digital watches and calculators to computer monitors and televisions.

What is the definition of Negative LCD display?

Negative LCD display has a black background, and numbers and letters are displayed in white (the natural color of the LCD screen), that is, light-colored characters on a dark background. Generally, a backlight is required to achieve the display effect. It is better to see clearly in the sun and outdoors. in e-book software. It can be matched with the color of the watch, has good visual impact, is not easy to reflect light, and has good concealment.

What is the difference between positive and negative LCD screen?

1. Positive display

The so-called positive display means that the color of the content displayed on the LCD screen is darker than the background color, such as: black characters on a yellow-green background (yellow-green screen) and black characters on a gray background (FSTN). This type of screen generally has a better display effect under sunlight. There is also a relatively simple way to distinguish, that is, the color of most positive display characters is black. I just said that this kind of screen has a good display effect in sunlight. not easily affected by 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 characters on a blue background (blue screen), white characters on a black background (VA segment code screen), such screens have relatively high contrast, and the display effect indoors is better than positive ones. There is also a relatively simple way to distinguish, that is, the color of most negative display characters is white, because the LCD screen itself does not emit light, the color of the negative display characters is actually the color of the backlight through the glass, the backlight is white The typed characters are 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 of negative display, which is color silk screen printing, and the LCD screen will become colorful and diverse after adding silk screen printing.

What are the advantages of Negative LCD display?

First of all, Negative LCD display has high contrast. Negative LCD screens have better black performance, making the dark parts darker and the bright parts brighter, so the contrast ratio is higher.

At the same time, when the liquid crystal molecules of the negative liquid crystal screen are energized, more light will pass through due to their deflection in the vertical direction, so that the benefits will come. There is no need for a high-power backlight (power saving).

Of course, the higher the contrast, the better. The higher the contrast, the more layers and information will be lost in the image, which is not conducive to the performance of image details; the lower the contrast, the less obvious the image layers will affect the overall performance of the image. A vague feeling. So neither low nor high is just right.

Secondly, the Negative LCD display also makes the overall voltage level of the screen more stable, which is of great benefit to the life of the screen, and since it does not require a high-power backlight, the heat generation and power consumption of the screen can be effectively reduced.

BIBUKE can customize all kinds of sizes liquid crystal display (LCD) with glass thickness 1.1mm, 0.7mm,0.55mm,0.4mm and the models of TN, HTN, STN and FSTN LCM with COB, TAB, COG, TFT and LED Backlight.
