Cái nào tốt hơn, Tường màn hình LED hoặc tường màn hình LCD?

Hiện tại, Có hai loại màn hình video phổ biến: LED display screens and LCD display screens. LCD display screens are more commonly used in televisions, which are commonly referred to as LCD TVs, while LEDs are more commonly used in commercial advertising video displays and stage performance background matching. To determine which is better, LED display or LCD display, we first need to understand what LED display or LCD display are.

One The concept of LED display screen and LCD display screen

LED is the abbreviation for Light Emitting Diode, a type of semiconductor light emitting diode, An LED display screen is composed of many small LED module panels. Each LED module panel, also known as an LED display screen module, is arranged in a matrix of many LED pixel points, and the distance between each LED pixel point is called the dot pitch.

LCD stands for Liquid Crystal Display, which is composed of a certain number of color or black and white pixels placed in front of a light source or reflective surface. Liquid crystal is a special substance between solid and liquid. It is an organic compound that is normally in liquid form, but its molecular arrangement is very regular like that of solid crystals, hence the name liquid crystal. The main working principle of LCD display screen is to stimulate liquid crystal molecules with electric current to generate dots, lines, and surfaces, which are combined with the back light tube to form the picture.

II Which is better, LED or LCD display screen?

1. LEDs are more energy-efficient

The energy-saving effect of LED display screen is 10 times that of LCD display screen, which means that under the same configuration, LCD consumes 10 times more power than LED.

2. LED has advantages in clarity and brightness

LED displays have a much higher refresh rate, trong trẻo, and brightness compared to LCD displays. And the LED display screen can still display clearly under strong sunlight, and its screen brightness will automatically adjust according to the outdoor environment brightness to achieve excellent video display effect.

3. Strong contrast of LED

A good LED display has a contrast ratio of up to 3000:1, while the contrast ratio of an LCD display is only about 350:1, which means that LED displays have much better contrast than LCD displays.

4. LED has a wide viewing angle

LED display screens can achieve a relatively large viewing angle, with a viewing angle of 165 °, and the video display is still clear.

Tuy nhiên, the viewing angle range of LCD is small, and if the viewing angle is slightly larger, it will not be clear and the video will become blurry.
