The Technical Core and Future Development of IPS Screen
The IPS screen is based on TFT technology and adds horizontal conversion technology to solve the problem of viewing angle, with a viewing angle of up to 178 degrees and accurate color With the continuous development of technology and widespread applicati
IPS screen is a widely used full angle display technology, and its development and innovation have solved the major problem of the viewing angle of display screens.
What is the viewing angle of a LCD screen?
Firstly, let's understand what is the viewing angle of a display screen. The so-called viewing angle of the screen refers to the maximum angle range of image clarity that we can accept when viewing the screen from different directions. Within this angle range, the image needs to maintain sufficient contrast and brightness. Beyond this angle range, we will not be able to view the screen image normally. The visual angle we refer to mainly includes horizontal and vertical angles.
The core technology of IPS full view screen is essentially a TFT LCD screen
which adds horizontal conversion technology on the basis of TFT technology. In the early days of its release in 2001, it was commonly known as Super TFT. The principle of IPS panel is to optimize the arrangement of liquid crystal molecules based on TFT technology, using a horizontal arrangement to make the two stages on the same surface. When an electric field is applied, the liquid crystal molecules rotate, allowing light to pass through and causing the display screen to appear. Due to the fact that the liquid crystal molecules in IPS panels do not distort, a larger viewing angle and color accuracy can be achieved. This is the technical core of IPS full view screens. The viewing angle of a regular TFT LCD screen is usually below 160 degrees, while the viewing angle of an IPS panel can reach 178 degrees. In addition to a large viewing angle, IPS panels also have advantages such as stable structure, rapid response, accurate color, and dynamic display without ghosting.
The Development and Progress Space of IPS Full View Technology
IPS screens have been constantly developing and improving since their introduction, and there are many other areas for advancement besides changing the arrangement of liquid crystal molecules through horizontal conversion technology. For example, the backlight of the screen also has a certain impact on the viewing angle. Excessive brightness may affect the contrast of IPS screens and cause the image to appear too white when viewed at a tilt angle. Therefore, IPS panels need to select suitable backlight brightness for debugging. In addition, the module structure and light source distribution of the backlight also need to be optimized to improve the viewing angle. Of course, there are other aspects that affect the viewing angle, such as adding reflective film, which can enhance the reflection of light and thus improve the viewing angle to a certain extent. There are also optical compensation technologies, etc. The purpose of these technologies is to improve the transmittance of IPS screens displayed at different angles, thereby ensuring color accuracy while increasing the viewing angle. IPS full view technology is constantly developing, and there will definitely be more technological breakthroughs in the future.
The future direction of IPS full view technology
The application fields of IPS full view technology are now very extensive, and its excellent viewing angle and color presentation are increasingly favored by people. For example, in the field of smart wearables, using IPS screens can provide better viewing angles, making it convenient for users to observe the information on the screen from various angles during outdoor activities and leisure. In the field of automotive displays, with increasing intelligence, all of these need to be presented through screens. The excellent viewing angle and response speed of IPS panels make it easier for users to observe the screen inside the car, and the user experience is also smoother. In the medical field, IPS displays can provide flexible viewing angles and more accurate color presentation for medical staff. With the continuous advancement of medical technology, they have also upgraded medical equipment better.
Overall, the future development trend of IPS full view technology is very promising and it remains the mainstream choice in the field of full view displays. With the advancement of technology and the expansion of application fields, IPS displays will have great development space in the future, and of course, it is not ruled out that better full view technology will emerge in the near future. Let's look forward to it.
