Compare Led Screen And Lcd Screen

WHAT IS LCD DISPLAY?

LCD screen, also known as liquid crystal display, is made up of pixels containing liquid crystals with the ability to change the polarization of light and change the intensity of transmitted light when combined with different types of light. polarizing filter. In other words, LCD is a technology that uses backlight to create light, not self-illuminating.

The LCD advertising screen has a uniformly distributed color gamut, and liquid crystal elements, which can block or allow light to pass through. This type of screen has a light source behind the liquid crystal elements, which when illuminated will make the image sharper.

WHAT IS LED SCREEN?

LED screen is a type of flat screen that uses light-emitting diode technology to project images and does not require background light. These diodes are linked together to form a larger display panel . In LED displays, the color space model is RGB representing the colors red - green - blue. The combination of these three colors allows you to create millions of colors, including white.

LED screens function like TV screens and projectors. But it has the advantage that it is not limited in size and resolution. We can customize the size depending on the actual use needs.

DIFFERENT CHARACTERISTICS BETWEEN LED SCREEN AND LCD DISPLAY

1. Contrast

The contrast of the led screen when presenting will be better than the LCD screen. Because the LCD screen's construction uses liquid crystals, it is not possible to cover 100% of the backlight and at that point a black screen is displayed but not completely black. In contrast to LCD screens, the black color displayed on LED screens is very good because there is no backlight.

2. Color display

With single-color LED technology, LED and LCD screens do not have too big of a difference. However, today with the improvement of technology, LED screens use 3 new RGB colors, making the colors of that product more diverse, truer and sharper than ever. This is also the strength of LED screens when compared to LCD screens.

3. Viewing angle

Although LCD screens are constantly changing and improving viewing angles, they are generally not much improved compared to LED screens. Currently, the LED Display screen has upgraded the viewing angle to 150 ^o , but the new LCD screen stops at 100 ^o viewing angle .

4. Screen Life

Currently, LED screens have a fairly long life expectancy of 100,000 hours. However, when used for a long time, the screen is prone to light leakage, reducing image quality.

As for the life of the LCD screen, it only achieves about 50,000 hours.

5. Power Consumption

Power consumption is one of the most concerned points. According to calculations, the power consumption of LED screens will be 40 % lower than LCD screens.

6. Brightness

The brightness of LED display panels ranges from hundreds to thousands and is much higher than LCD screens. Even under direct sunlight, LED screens can display clear images while LCD screens are easily affected by ambient light.

7. Size and price

- Size: LED screens can be of any size depending on the intended use. In addition, LED screens can be created in a variety of forms to meet creative display requirements, but LCD screens are usually only available in standard sizes set by the manufacturer.

- Price: Currently on the market, the price of LED screens will be higher than LCD screens mainly because of the quality and resolution of each type of screen.

SHOULD CHOOSE LED DISPLAY OR LCD DISPLAY?

In terms of advantages and disadvantages, each type will have superior characteristics. Therefore, based on the characteristics and needs of use, choose the appropriate screen type

However, if you use the screen for events, indoor or outdoor advertising, etc., HSV Media recommends choosing LED screens because of the following outstanding features:

- Long life: The brightness of the LED screen, although it will gradually weaken over time, not turn off completely. Moreover, we can take advantage of the replacement, so the use time is also extended.

- Reduce energy costs, help save electricity : because the LED display technology is simpler, the power consumption of LED is lower than LCD, so it helps businesses when installing continuous projection. It will save you a lot of money.

- Safe in use : LED bulbs do not contain mercury and harmful chemicals, so they will be safe for health when used. Moreover, the LED screen does not produce ultraviolet rays and the UV index is zero, so it will be absolutely safe to use.

- Flexibility : LED bulbs are more durable, less broken, resistant to strong impacts and can be used flexibly, suitable for hot and humid climate conditions in our country.
