IPS screens are one of the most popular types used in electronics today. Smartphones, tablets, computers, monitors, all kinds of products are using these screens. To understand the operation of this screen may help you to better understand the screens and see the advantages of this technology over the other.
What is the Screen IPS?
IPS is an acronym for in-plane switching is a screen technology that is used with LCD screens. The switching technology plan has been designed to meet the limitations in the LCD screens from the end of the 1980s that used an array of field effect nemático twisted. The method TN was the only technology available at the time for LCDs active matrix TFT (Thin Film Transistor – Thin Film Transistor). The main limitations of the LCDs of the array of field effect nemático twisted are the color of poor quality and a viewing angle narrow. LCDs with IPS screens offer better color reproduction and viewing angles wider.
The IPS Technology in the Screens
Are commonly used in smartphones in medium and large and portable devices. Monitors and televisions are examples and, more recently, the wearables have pastusing this type of screens in products such as smartwatches and even glasses. It is one of the types of technologies most popular and more cheap for LCD screens.
How Does a LCD Screen of IPS? Spends More Energy?
IPS-LCDs feature two transistors for each pixel, while the TFT-LCDs use just one. This requires a background light more powerful, which offers more accurate colors and allows the screen to be viewed from a wider angle.
IPS-LCDs do not show when the screen was touched, which you may notice on some older monitors. This is particularly advantageous for touch screens, such as smartphones and laptops touch-screen.
The downside is that an IPS-LCD consumes more power than a TFT-LCD, possibly up to 15% more. They are also more expensive to make, and they have response times longer. Compared to AMOLED screens, IPS screens consume even more.
Advances in IPS Technology
The IPS has undergone several stages of development within large companies. The advances in technology, starting with improvements to the angle of vision and problems with color shift. The transmittance is also being improved, as well as the contrast ratio. This, by the way, has been the focus of most of the improvements in IPS screens, in addition to the response time of the screens to the commands. The increase of color has also contributed to screens even better.
Alternatives to IPS Screens
Samsung has introduced the Super PLS (Plane-to-Line Switching) as an alternative to IPS. It is similar to IPS, but with the additional benefits of a better viewing angle, a brightness increase of 10%, a panel flexible, better image quality and a cost 15% lower than that of the IPS-LCDs. In 2012, the AHVA (Advanced Hyper-Viewing Angle) was introduced by AU Optronics to provide an alternative IPS that featured panels are similar to IPS, but with update rates higher. We still have the AMOLED screens that, despite being more expensive, they produce a contrast much larger and colors more vivid.
