4K Ultra High Definition (UHD) streaming, player and Blu-ray Disc businesses are growing rapidly. 4K UHD content contains more than 8 million pixels per frame – 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 HD content. We are used to using large-screen TVs, 50-inch 1080p TVs are almost everywhere, and the price of 4K TVs is gradually becoming close to the people. However, if you want to experience the details displayed by four times the 1080P TV, we can reasonably assume that we need four times the screen size. This means that 4K UHD projection is the only display technology that can display very large images at a reasonable price.
In a school or business environment, the projection display is very effective and allows the viewer to view all the details. In home entertainment, projection can also bring a wonderfully immersive experience. The true 4K UHD display solution delivers 8 megapixels in 4K UHD specifications for accurate, clear images, giving you all the details.
Key factors in 4K UHD technology
A pixel is just a very tiny unit in the picture. 4K UHD content has 8 million pixels per frame, but not all pixels display the same. The 4K UHD's more than 8 million pixels are all displayed to produce accurate images. To fully display all the details of 4K UHD content, display devices need to have excellent American National Standards Institute (ANSI) contrast, as well as pixels that are perfectly calibrated, high imaging speed, and high quality image processing.
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 standard display image contrasts, but these contrast options do not appear dark and bright in the same picture at the same time. For example, a simple "on/off" contrast indicator compares only full white and dark screens, but since the real image is viewed in a single image, the darkest black and brightest white are displayed in the same image. important. With excellent ANSI contrast, the image is crisper, clearer and more immersive.
The imaging panel is the core component of the projector. Panel technology is typically based on liquid crystal display (LCD), liquid crystal on silicon (LCOS) or Texas Instruments (TI) DLP® technology to form an array of imaging elements. The pixels seen on the screen are all generated by these imaging elements. In DLP technology, the imaging element is a series of micromirrors, and the size of a single micromirror is about the size of the human red blood cells. Devices using DLP technology can accommodate millions of micromirrors, and switching speeds are unimaginable.
Some projectors use different imaging panels to form three primary colors: red, green, and blue. Each component image panel must be precisely aligned to ensure accurate overlap of the three primary colors in each pixel. The smaller the pixel size, the harder it is to align the imaging panel during manufacturing. If the red, green, and blue pixels are misaligned, the display color will be skewed.
DLP single-chip technology uses only one imaging panel to display all colors, avoiding possible misalignment problems, so it is a great technology for obtaining high-resolution images and 4K UHD content.
Look closely at the white text on a black background – if you see red, green, or blue at the edge of the text, the imaging panel might be misaligned. Pixel calibration errors can cause color distortion in 4K UHD images.
The pixel size will shrink as the resolution increases. The 720P resolution image has 1 million pixels. The image at 1080P resolution has 2 million pixels. The 4K UHD presents 8 million pixels on the projection screen. Currently, 4K UHD imaging components are very small in size, making calibration difficult when using multiple imagers. This is one of the biggest challenges facing 4K UHD projection technology.
Let all the pixels do their best
The American Consumer Technology Association (CTA) defines 4K UHD as a technology that can display 8 million pixels on the screen. But in fact not all "4K" projection technologies present 8 million UHD-specified 8K pixels on the screen; some show only 4 million pixels. In order to take advantage of the large amount of detail in 4K UHD content, it is obviously crucial to display 8 million pixels. Check the specifications of the technology you plan to use. Find the UHD acronym.
One of the tasks of displaying 4K Ultra HD is to display all the details on the screen in a cost-effective way. It is one of the effective ways to generate a plurality of pixels using an imaging element and present a very high-quality 4K UHD projection of 8 million pixels. This can be achieved by integrating high-speed imaging and advanced signal processing. DLP 4K UHD technology uses advanced image processing algorithms to create bright, clear, and accurate high-resolution images.
Why is 4K UHD technology so widely used?
4K content is full of dynamic and rich details. With the right 4K UHD projection technology, the details are clearly presented in a more valuable way. Imagine the application of display technology in business. During the presentation, you want everyone in the room to see the details of the slide clearly. Do you often see slides with dense forms, and you need to work hard to see the numbers above?
The 4K UHD projection display can improve the readability of these contents, present clear characters, generate smooth curves and borders, making it easier to read and view visual data. 4K UHD is also suitable for schools and helps students view and read as much content as possible. For home entertainment, the 4K UHD device can fully project an oversized screen for the ultimate entertainment experience. Advanced devices with 4K UHD technology also feature a portable 4K experience that allows users to carry devices and view on-demand content. 4K UHD DLP technology is known for accuracy, precision and detail, improving business efficiency, enabling more effective education and more immersive home entertainment.
The application of 4K UHD projection display technology has broken through the traditional projection display market, such as commercial, educational and home theater, to new areas such as digital signage, laser TV and mobile smart TV.
Digital signage allows companies or organizations to deliver real-time information on public facilities, such as restaurants or billboards. 4K UHD devices support high-definition detail and huge display screens, both of which are effective ways to deliver information.
Laser TV is a new application for 4K UHD ultra-short-focus projection display, designed to play streaming media-on-demand video in ambient light conditions such as the living room. Consumers can place the product on the floor and project a 100-inch or larger display on a specific ambient light-suppressing projection screen or wall. Designed for the modern lifestyle, Laser TV delivers a huge display even when 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) illumination. This product is almost exclusively focused on streaming media-on-demand content, and almost never comes with ambient light suppression screens. In general, the brightness of a laser TV can reach 3000 lumens, but in general, the brightness level of a mobile smart TV is 1500 lumens or less than 1500 lumens. These products are driving the development of 4K UHD displays to handle the rapidly growing 4K UHD streaming content. The 4K UHD mobile product is compact and easy to carry, making it easy to move 4K UHD displays to new locations. For more information on mobile smart TVs, check out online training.
Extend the use of 4K UHD
Based on the DLP660TE chipset released last year, TI has introduced two small chipsets - DLP470TE and DLP470TP. The DLP470TP is the most compact 4K UHD solution in DLP products, optimized for size and power. This chipset is ideal for applications that require mobility and brightness levels below 1500 lumens. DLP470TE and DLP470TP have many features in common, but the former can be optimized for projectors with brightness levels above 1500 lumens. The DLP470TE has a larger package size than the DLP470TP and has a brightness level of 4000 lumens.
With a small diagonal of 0.47 inches, 8.3 million pixels can be displayed in a smaller design module, creating a more cost-effective display solution for the mainstream market. Each micromirror of the DLP470TE and DLP470TP 4K UHD chipsets displays four pixels and supports the 4K UHD minimum digital micromirror chip (DMD) based on DLP technology. The DLP 4K UHD chipset series supports different brightness levels, and uses the high-brightness features of the chipset and small outline package for system development. It can be used in various terminals such as laser TV, digital signage, games, corporate and educational projectors, and mobile smart TVs. Among the products, DLP 4K UHD pushes display products to unlimited possibilities.
