How to distinguish the LCD screen from the forward LCD screen to the reverse LCD screen?

What is an LCD screen?

LCD (Liquid Crystal Display) screen is a liquid crystal display technology, which is composed of liquid crystal molecules and electrodes. When a voltage is applied to the electrodes, the liquid crystal molecules change direction, thereby changing the direction of light propagation, thereby realizing image display. LCD screens have the advantages of low power consumption, high resolution, and high brightness, and are widely used in modern electronic equipment. Among LCD screens, there are two types: forward-facing LCD and reverse-facing LCD.

The difference between forward LCD screen and reverse LCD screen

The main difference between the forward LCD screen and the reverse LCD screen is the way the voltage is applied. In the forward liquid crystal screen, the voltage is applied to the plane direction of the liquid crystal molecules, and the liquid crystal molecules will be aligned along the direction of the electric field, thereby changing the direction of light propagation and realizing image display. In the reverse LCD screen, the voltage is applied in the vertical direction of the liquid crystal molecules, and the liquid crystal molecules will be vertically aligned along the electric field, thereby changing the direction of light propagation and realizing image display.

The color performance of forward-facing LCD screens and reverse-facing LCD screens is also different. The color of the positive LCD screen is brighter, while the color of the reverse LCD screen is softer. When choosing an LCD screen, you need to choose according to your specific needs.

The characteristics of positive LCD screen

The positive LCD screen has the following characteristics:

1. Good display effect: the display effect of the front-facing LCD screen is relatively bright, with a high degree of color reproduction, and can display more realistic colors.
2. Wide viewing angle: The viewing angle of the front-facing LCD screen is relatively wide, and the screen can be viewed from different angles without problems such as color distortion.
3. Low energy consumption: The energy consumption of the positive LCD screen is relatively low, which can save power and prolong battery life.

How to choose a positive LCD screen?

When choosing a positive LCD screen, you need to choose according to your specific needs. Here are some considerations for choosing a positive-facing LCD screen:

1. Resolution: The higher the resolution, the better the display effect, but the more expensive the price
2. Size: The larger the size, the better the display effect, but the more expensive it is.
3. Brand: choose a well-known brand positive LCD screen, the quality is more guaranteed.

Summarize

The difference between the forward LCD screen and the reverse LCD screen is that the voltage is applied in different ways. The forward LCD screen is characterized by good display effect, wide viewing angle and low energy consumption. When choosing a positive LCD screen, you need to choose according to your specific needs, including resolution, size and brand.
