The Advantage and Shortcoming of IPS Panel

- Dec 17, 2018-

  IPS is the abbreviation of English In-Plane Switching. The English meaning is the flat conversion screen technology. The liquid crystal panel technology introduced by Hitachi in 2001 is commonly known as "Super TFT". It is the most advanced LCD panel technology in the world and has been widely used. In the display panel such as liquid crystal display and mobile phone screen.


What does the IPS screen mean?


  In general, the IPS screen is a screen that uses IPS technology. Compared with the normal display screen, it has a clearer and more detailed dynamic display effect, and the visual effect is more outstanding. Therefore, when we select the LCD display or the smartphone screen, The IPS screen will perform even better. Because of this, the general IPS screen LCD monitor or smart phone will become a big selling point often mentioned by merchants.


IPS screen advantages


  As the most advanced LCD panel technology, many flagship mobile phones or some brand LCD monitors now use IPS screens, such as Samsung Note4, iPhone6 and other well-known models, all using top IPS panel screens. What are the advantages of the IPS screen? Listed below.


 Large viewing angle


  The viewing angle of the IPS screen panel can reach 178 degrees, and the degree of color change produced when viewed from the front and at different angles becomes the color distortion rate, and the obtained value is almost indistinguishable from the naked eye. It means that the effect of viewing the picture from the front or the side is the same.

IPS screen shortcomings


  There are advantages and disadvantages, and what are the disadvantages of the iPS screen?

  Since the IPS screen adopts the arrangement of the horizontal liquid crystal molecules, the viewing angle is increased while the penetration of the light is reduced. In order to better display the bright color, the illuminance of the backlight is increased, so the light leakage phenomenon is extremely common in the IPS screen. As the screen increases, the problem of large-area edge leakage has been a criticism of IPS.


  Because the IPS screen can't improve the penetration and improve the backlight, it also loses its high contrast competitive advantage. The static contrast ratio of the general IPS is between 2000:1 and 3000:1. The static contrast of the AV screen can easily reach 5000:1, so the contrast is not high, which is also a disadvantage.
