Comparison of Led Screen and Lcd Screen

WHAT IS LCD SCREEN?

LCD screens, also known as liquid crystal displays, are made up of pixels containing liquid crystals that can change the polarization of light and change the intensity of transmitted light when combined with polarizing filters. To put it more simply, LCD is a technology that uses a backlight to create light and cannot emit light itself.

LCD advertising screens have a uniform 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, when illuminating these elements, it will make the image sharper.

WHAT IS LED SCREEN?

An LED display is a flat panel display that uses light-emitting diode technology to project images and does not require a backlight. These diodes are connected together to form a larger display panel . In an LED display, the color space model is RGB, which stands for red, green, and 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 the advantage is that they are not limited in size and resolution. We can choose the size depending on actual usage needs.

DIFFERENT FEATURES BETWEEN LED SCREEN AND LCD SCREEN

1. Contrast

The contrast of the LED screen when displaying will be better than the LCD screen. Because the structure of the LCD screen uses liquid crystals, it cannot cover 100% of the backlight and at that point the black screen is displayed but not completely black. In contrast to the LCD screen, the black color displayed on the LED screen is very good because there is no backlight.

2. Display color

With single-color LED technology, LED and LCD screens do not have much difference. However, today with technological improvements, LED screens use 3 new RGB colors, making the product's colors more diverse, realistic and sharper than ever. This is also the strength of LED screens when compared to LCD screens.

3. Perspective

Although LCD screens are constantly changing and upgrading their viewing angles, they are still not much improved compared to LED screens. Currently, LED Display screens have upgraded their viewing angles to 150 ^degrees , but LCD screens are still stuck at 100 ^degrees .

4. Screen life

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

As for the lifespan of an LCD screen, it only reaches 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 that of LCD screens.

6. Brightness

The brightness of LED display panels ranges from hundreds to thousands and is much higher than that of LCD screens. Even under direct sunlight, LED screens can display images clearly 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 many different 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 I CHOOSE LED SCREEN OR LCD SCREEN?

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

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

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

- Reduce energy costs, help save electricity : because LED screen display technology is simpler, LED power consumption is lower than LCD, so businesses that need to display continuously will save a lot of costs.

- Safe to use : LED bulbs do not contain mercury and toxic chemicals, so they are safe for health when used. Furthermore, LED screens do not produce ultraviolet rays and the UV index is measured at 0, so they are absolutely safe to use.

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