4K Ultra HD, to see more exciting world

4K UHD Streaming Media, Players and Blu-ray Disc Services Are Growing Rapidly 4K UHD Content Each frame contains more than 8 million pixels - more than four times the amount of Full HD (1080p) content.

The challenge is how to present the details, depth of field and immersive look of 4K ultra-high definition content.We are accustomed to using big screen TVs, 50-inch 1080p TVs are almost everywhere and the prices for 4K big TVs are gradually reaching.However, If we want to experience the detail shown on a quadruple 1080p TV, we can also reasonably assume that a quadruple screen size is needed, which means that 4K UHD Projection is the only display technology that delivers oversized pictures at a reasonable price.

Projection display is very effective in school or business environment, so that the audience can watch all the details in the projection of the home entertainment can also bring a wonderful immersive experience. 4K UHD real 4K display solution to demonstrate the requirements of the UHD 800 million pixels, showing accurate, clear images, let you see all the details.

4K UHD technology, the key factor

A pixel is just a tiny element of a picture. 4K UHD content has 8 million pixels per frame, but not all pixel displays are the same. 4K UHD's full display of more than 8 megapixels produces an accurate picture. To fully display all the details of 4K UHD content, display devices need to have excellent ANSI contrast as well as pixel, high image speed and high quality image processing for perfect calibration.

Images with high ANSI contrast can appear very dark black and very bright white in the same picture, showing the true contrast of the image.Many techniques introduce other standards for displaying image contrast, but these contrast options can not be in the same picture at the same time For example, a simple 'on / off' contrast indicator only contrasts with all-white and dark screens, but displays the darkest black and the same image in the same image because the real image is viewed in a single image The brightest white is paramount, and with excellent ANSI contrast, images are crisper, crisper and more immersive.

The imaging panel is a core element of the projector Panel technology typically consists of an array of imaging elements based on Liquid Crystal Display (LCD), Liquid Crystal on Silicon (LCOS) or Texas Instruments DLP® technology The pixels seen on the screen are represented by these images In the DLP technology, the imaging element is a series of micromirrors, the size of a single micromirror is approximately the size of a human red blood cell, and the number of micromirrors in a DLP-based device accommodates millions, making the switching speed unimaginable.

Some projectors use different imaging panels to create three primary colors: red, green, and blue. Each panel must be precisely aligned to ensure accurate overlap of the three primary colors in each pixel. A smaller pixel size aligns the imaging panel during manufacturing The more difficult it is to do. If the red, green and blue pixels are misaligned, the display colors will be distorted.

DLP single-chip technology displays all colors with just one imaging panel, eliminating possible misalignments, so it's a great technology for high-resolution images and 4K UHD content.

Carefully look at the white text on a black background - If you see red, green, or blue at the edges of the text, the imaging panel may be misaligned Pixel calibration errors may cause the color of a 4K UHD image to be distorted.

Pixel size will be reduced with increasing resolution 720P resolution image has 1000000 pixels 1080P resolution image has 2 million pixels 4K UHD projection screen projection pixel is 8000000. At present, 4K UHD imaging components are small in size and difficult to calibrate when using multiple imagers, one of the biggest challenges for 4K UHD projection technology.

Let all the pixels make the best use of them

The CTA defines 4K UHD as a technology that can display 8 million pixels on the screen, but not all '4K' projection technologies actually render 4K UHD's specified 8 million pixels on the screen ; Some with only 4 megapixels. To take full advantage of the large amount of detail in 4K UHD content, it is clearly crucial to display 8 million pixels. Check out the specifications of the technology you are planning to use. Find UHD acronyms.

One of the tasks of displaying 4K Ultra HD is to display all the details on the screen in a cost-effective way Producing multiple pixels with imaging elements in an extremely high quality 8-megapixel 4K UHD projection is an effective way This is achieved through the integration of high-speed imaging capabilities and advanced signal processing capabilities.The DLP 4K UHD technology utilizes advanced image processing algorithms to create bright, clear, precise high-resolution images.

Why 4K UHD technology is so widely used?

4K content is full of dynamic rich details. With the help of the appropriate 4K UHD projection technology, the details are clearly presented in a more valuable way. Imagine the display technology in the commercial application. During the presentation, you want everyone in the room You can clearly see the details of the slides.Do you often see slides with dense forms, and you need to work hard to see the numbers above?

4K UHD Projection Displays can effectively improve the readability of these content, render clear characters, generate smooth curves and borders, making it easier to read and view visual data. 4K UHD also works in schools to help students view and read as much as possible For home entertainment, 4K UHD devices are perfectly capable of projecting oversized screens to create the ultimate entertainment experience.Advanced devices using 4K UHD technology also have a portable 4K experience that lets users bring their devices and view on-demand content. 4K UHD Known for its accuracy, precision, and detail, DLP technology improves business productivity, enables more effective education and more immersive home entertainment.

The use of 4K UHD projection display technology has surpassed traditional projection display markets such as commercial, educational and home theater to include new areas such as digital signage, laser televisions and mobile smart TVs.

Digital signage lets companies or organizations deliver real-time information on utilities such as restaurants or billboards, etc. 4K UHD devices support high-definition details and a huge display, both of which are effective ways to deliver information.

The Laser TV is a new application for 4K UHD ultra-short throw projection displays designed to play streaming on-demand videos in ambient light conditions in living rooms, etc. Consumers can place products on the floor, suppress the projection screen in a specific ambient light, A 100-inch or larger screen is projected onto the wall. The laser TV is designed for modern living and can display a huge display even while it is moving. Typically, 4K UHD laser TVs use DLP technology to deliver unparalleled HD content and immersive experience.

In general, mobile smart TV products use light-emitting diode (LED) lighting, which focuses almost exclusively on streaming media-on-demand content with almost no ambient light suppression screens, which typically deliver up to 3000 lumens of laser, but generally , The brightness level of mobile smart TVs is 1500 lumens or less than 1500 lumens These products are driving the development of 4K UHD displays in response to the rapidly increasing number of 4K UHD streaming media 4K UHD mobile products are compact, Easy to carry, you can easily migrate your 4K UHD display to new locations For more information on mobile smart TVs, check out the online training.
