IPS display in modern electronic devices

Monitors for computers, televisions, telephones - a technology based on liquid crystals, which has found its application in many electronic devices and has become familiar and everyday. But do you know what is noteworthy for the display of IPS, how it is arranged and what excellent qualities it has? First of all, it is worth mentioning that the abbreviation with English stands for "high-quality LCD matrix." It was established in 1995 to eliminate the disadvantages of TN technology. In contrast, monitors consist of their liquid crystals, which are located parallel to the monitor and rotate all at once under the influence of an electric field. That's why the IPS display has such a remarkable feature as a wide viewing angle. It can be up to 170 °.

The scheme of the device is as follows The first layer is the front polarizer, then the light filter layer and the guides. Next are liquid crystals, electrodes, control transistors. The rear polarizer and the backlight unit complete the design of the monitor. If you see that the IPS display has broken pixels, then they will be black, not white. This is due to the fact that the LC molecules do not rotate if they do not receive an electronic voltage, and do not transmit light, since the second filter is in the perpendicular position with respect to the first. For this reason, the black color is remarkably transmitted by the matrix.

What else are remarkable monitors created with this technology? They are able to transmit high contrast, wide-spectrum colors, very rich, natural and deep, corresponding to the RGB scale. Therefore, devices that have an IPS display, suitable for working on the Internet, watching movies and photos, they are loved by professionals involved in graphics, image processing. Of the positive qualities that such a screen possesses, one can note its safety for the eyes. The statement can be trusted, the verdict was taken by ophthalmologists. But technology has disadvantages: high cost and long response time.

Currently, smartphones, televisions, laptops, tablet computers, telephones with a touch-screen IPS display are available , allowing you to easily manage the functions of electronic devices. The Japanese corporation "Iiyama" produces high-quality monitors that support the projection-capacitive technology. The monitor is resistant to external influences, transmits an image of high quality. You can control it by touching a few fingers or using a magnetic pen.

Firms engaged in the production of electronics are promoting new developments. For example, VA. The name can be translated as "vertical alignment". This is a compromise version, which was developed since 1996 and is intended to combine the best of the previous technologies. Of the successful modifications can be mentioned TFT U-IPS, TFT H-IPS. But the most promising are the IPS matrices. They pay special attention to the company "LG", "Panasonic". Device models are created that have an IPS-TFT type of display (it was developed by the companies "Hitachi" and "NEC"). When they are manufactured, not only quality is taken into account, but also a well thought out design, as well as affordable prices.
