What is an IPS panel?

The IPS panel is an In Panel Switching panel. In general, the liquid crystal of the panel (TN/MVA) is a rotary upright type, and the liquid crystal of the IPS panel is a horizontally rotating type. The TN type panel uses voltage to shift the liquid crystal molecules from the horizontal panel arrangement to the vertical panel arrangement. The MVA type panel uses voltage to transfer the liquid crystal molecules from the completely vertical panel to an angle with the panel. The liquid crystal molecules are rotated and stood up under the control of the electric field. , let the light through, the user will see the screen will be shiny. However, due to the relationship of the rotation angle of the liquid crystal, the light transmitted by the light is more directional, resulting in the deviation of the light and the color seen by the naked eye at different angles, so-called gray-scale inversion and color shift. At the same time, in the process of rotation, the liquid crystal near the glass side is affected by the alignment film (PI), the station will not stand straight and there will be non-uniformity, so it will cause different angles and affect different light transmission characteristics.

The flat-bed type liquid crystal of the IPS panel rotates on a plane and has less directionality, and the IPS technology uses the technology to improve the defect that the alignment film affects the liquid crystal, and allows the light to pass through by lying flat and rotated by 90 degrees. Azimuth can effectively improve grayscale inversion and color shift.

The IPS wide viewing angle technology makes a fuss about the orientation of the long axis of the liquid crystal molecules. The difference is that the liquid crystal display using the IPS wide viewing angle technology allows the observer to see only the short axis of the liquid crystal molecules at any time, so the picture is viewed at various angles. There will not be much difference, which will improve the viewing angle of the LCD monitor perfectly.
