We are in a colorful world. In order to present this colorful world to our eyes through the Display screen, human beings invented cameras, video cameras, televisions and other equipment, and also developed many advanced technologies. HDR is one of them. .

What is HDR?

The full name of HDR is High-Dynamic Range, that is, high dynamic range image technology. This technology was first applied to photography. Turning on HDR during the shooting process can make the original dark scene brighter and more transparent. Now, HDR technology has been applied to various aspects such as home appliances and smart terminals.

What can HDR bring?

Take a computer monitor as an example. The range of brightness that can be displayed by traditional displays is extremely limited, which is far from the range that the human eye can perceive. The reason is that the brightness of the traditional display in the bright part of the screen cannot be increased, and the dark part cannot be darkened. This leads to a poor sense of layering in the final perception of the human eye, and a lot of details are lost.

HDR ultra-quality display technology can perfectly solve this problem. Compared with the mainstream SDR 1080P display technology on the market, HDR has a higher pixel load: 3840×2160; a wider color gamut range: BT2020. The same picture can display more color information and more detailed textures of the image. At the same time, with more advanced electro-optical conversion technology, the light and dark contrast of the picture is improved in all directions, so that a picture can show the most realistic appearance in all directions.

HDR and IPS hard screen

When it comes to IPS hard screens, it is well-known. LG Display’s “Golden Sign” has not only made many TV manufacturers “love”, IPS hard screens have given us a good reputation for excellent performance, durability and reliability. The 4-color HDR LCD panel is based on the IPS hard screen, and the HDR technology is directly embedded on the panel, which integrates the HDR characteristics into the blood source of the LCD panel. This is the most essential difference between the 4-color HDR LCD panel and other LCD panels.

The 4-color HDR LCD panel not only can better analyze the HDR film source, but also has the characteristics of ultra-wide viewing angle, high brightness, and low energy consumption. More importantly, the 4-color HDR LCD panel continues the IPS hard screen with ultra-wide viewing angle and color. The advantage of high degree of reduction is of great significance to mainstream consumer groups.

Nearly complete presentation of HDR film source effects

HDR technology improves the picture quality effect, but what restricts its further development is the problem of film source. The HDR algorithm independently developed by LG Display can convert ordinary SDR film sources into close to HDR image effects, greatly improving the application field of HDR, and not only that, it can also improve the HDR image effect when playing HDR film sources.

For this reason, LG Display takes the lead in embedding HDR technology on the 4-color ultra-high-definition LCD panel. The HDR algorithm can be optimized to present the HDR film source almost unreservedly to the audience, making the picture closer to the real scene, and details in the dark. Better performance. So, how to determine whether the HDR effect of a TV product is good or not, the measurement data certified by the authority is the most convincing.

In summary, HDR technology is not simply attached to a screen. It requires complete HDR shooting, HDR chip decoding and then HDR screen display to present higher quality content. LG Display’s 4-color HDR technology can be regarded as the best LCD technology for HDR technology with its “HDR algorithm embedded in the LCD panel”.
