LED backlight

HD screen means high-definition screen. HD is actually the standard of high-resolution digital TV. At present, 16:9 screens adopt this standard, with a resolution of 1280 x 720 (720p / 720I). It is generally used in digital products, similar to digital cameras. MP5 and MP4 all use this resolution, while notebook computers generally use the resolution of 1366 x 768.

In my opinion, there is no big difference. The backlight is all led. High definition should be reflected on the screen. Maybe the density of the filter in front of the backlight is not the same. If you buy it, it is recommended that led is enough. You don't have to have high definition. The computer's graphics card may not be able to bring high-definition things, not to mention the so-called high definition, It's not necessarily very HD

Led actually refers to the backlight mode of the display screen. In the early days, CCFL backlight was just two lamps, one on the left and one on the right, and the effect was not as good as LED. In fact, there are two rows of LEDs, one on the left and one on the right, but there are dozens of LEDs on each row. This effect is more uniform than that of CCFL. And the brightness is higher.

LED backlight refers to the display screen that uses LED as the light source. The liquid crystal itself can't emit light, so it needs additional light source. Generally, we use cold cathode tube as the light source. Compared with LED, the cold cathode tube has a lot of heat and a corresponding increase in volume. Therefore, the display screen of LED backlight saves power and is thinner LED backlight/

The so-called inner screen is LCD screen. Since there is LCD in the name of LED LCD, it must contain LCD screen, so there must be inner screen. The so-called LED is the backlight, using LED as the backlight, which is more energy-saving than the traditional CCFL light source.

At present, it is recommended to use LED backlight LCD TV for home use. LED TV uses LED color lights arranged in one plane to realize one pixel by controlling the brightness and degree of LEDs at different positions on the screen. Like the principle of LED advertising TV in square and other places, it is composed of many dense small lights. The feature of LED TV is that each point is a light, and it emits its own light, The advantage is high brightness, can be very bright: LED backlight LCD TV principle is like our common light box, first inside the white led directly illuminate the whole screen, and then cover the light box cloth in front, different from the light box is the light in front of the light box/

LED display? At present, there is no led desktop display on the market. There is only LED backlight LCD. There is no principle for LED backlight LCD. It's just that the original CCFL backlight is replaced by LED backlight. Everything else is pretty much the same,

LCD (liquid crystal screen) itself can not emit light, to be exact, it is shading. In order to display the restored image, it is necessary to use the background light source (backlight) to transmit the LCD screen to get the image.

LED backlight refers to the use of LED as the backlight of LCD. Compared with the traditional cold cathode tube backlight, LED has the characteristics of low power consumption, low calorific value, high brightness and long service life. The brightness of LED backlight is high, and the brightness will not drop after long-time use. Moreover, the body of LED backlight is thinner, the appearance is beautiful, and the color is softer. The color of hard screen panel can make the eyes more comfortable. All led backlights have it, which saves electricity and reduces environmental radiation.

LED backlight refers to the use of LED (light emitting diode) as the backlight of LCD. Compared with the traditional CCFL (cold cathode tube) backlight, LED has the characteristics of low power consumption, low calorific value, high brightness and long service life, which is expected to completely replace the traditional backlight system in recent years. The Chinese character explanation of backlight is "light can not be directly illuminated" or "avoid the direct illumination of light".

At present, the representative manufacturer of LED TV with side entry backlight in the market is Samsung. From its products, we can see that its shape is as thin as a finger and very beautiful. Although the side entry backlight can be very thin, it is more difficult and has higher technical content. It includes a lot of technical problems, such as heat dissipation problems, such as side light control, light reflection, uniformity and so on. Each one is not clear in one or two sentences.
