IPS LCD module

Blaze Display Technology Co., Ltd. | Updated: Nov 27, 2018

IPS LCD is the TFT display with supper wide viewing angle, instead of traditional TN TFT display have the limited viewing angle, the viewing angle of IPS LCD module could be 178 degree in typical, customer could watch the image in all direction without color inversion and get the high contrast display image. Compare to TN TFT, IPS TFT display is more suitable for TFT touch screen.


Why choose IPS LCD Module?

  1. Wider viewing angles – crystals are aligned horizontally rather than vertically, so it allows for better angled viewing, perfect for smaller screens, where you need to rotate the screen for better viewing
  2. Lower power consumption, resulting in longer battery life – again for smaller screens, this works great, because even though this technology requires more power, a smaller screen has less power drain.
  3. Brilliant color image – this is a huge advance in technology, from a Twisted Nematic (TN) display that only produced 6-bit color, to an 8-bit color display with the IPS technology
  4. Variations to help with user’s viewing requirements or desires – there are several different forms of IPS technology: Super-IPS, (S-IPS) Advanced Super IPS, Advanced S-IPS, where the liquid crystal molecules stay parallel to the front and back panels, instead of perpendicular when a voltage is applied
  5. Consistent, accurate color, under different viewing angles
  6. Clear images and stable response time, which allows for faster response time – good for videos.

What is IPS LCD :

PS (In-Plane Switching) LCD is still a type of TFT LCD, different to regular TFT in TN (Twisted Nematic) mode, the IPS LCD liquid crystal elements inside the TFT LCD cell, they are arrayed in plane inside the LCD cell when power off, so the light cannot transmit it via the IPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS TFT would switch in a small angle, then the light would go through the IPS LCD display, then the display on since light go through the IPS display,  the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.
