What is IPS panel?

In-plane switching (IPS) was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time. Its name comes from the main difference from TN panels, that the crystal molecules move parallel to the panel plane instead of perpendicular to itas shown in Figure 1. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide viewing angles and good color reproduction.

As a global leader in liquid crystal display technology manufacturers, LG Display's IPS technology LCD panels have been favoured unanimously by industrial professionals. Top brands such as EIZO, NEC, APPLE, and other professional display products, are using IPS Hard-screen LCD technology to meet the demanding requirements of colors for industrial professionals in design, printing, aerospace, medical imaging.

The most visual difference is that, direct touch on IPS hard-screen doesn't effect ripple when touching VA / TN soft screen, as shown in Figure 2.

How to tell IPS panels?

1). Touch it and check whether there is a ripple; if yes, It is soft screen instead of IPS panel;
2). Use magnifier and check the pixels arrangements, see Figure 3 as below:

IPS technology LCD has several advantages compared with TN panels:

1. It delivers the real blur-free dynamic videos.

IPS delivers blur-free dynamic images

2. It has uniform response to dynamic videos;

IPS has uniform response

3. It ensures zero color shift.
4. Low power-consumption, green technology
5. Wider viewing angle: vertical and horizontal viewing angle of 178 degrees
6. High accuracy in color and image quality.

As the specialist manufacturer of LCD photoframe, RONBEN takes a new step forward and launched a 9.7 inch LED backlit IPS panel photoframe, check the Specs of the 9.7 inch IPS panel here( panel brand:LG, part No.:LP097X02-SLA3).
