What exactly is an IPS display?

For more than a century, display technology has been driving innovation in the electronic device market. In the 1990s, IPS technology was developed to address color and viewing angle issues. Today, IPS display panels outperform other popular display planes in terms of color and viewing angles, including VA (vertical alignment) and TN (twisted nematic).

What exactly is IPS?

IPS (In-Plane Switching) is a screen display technology used in liquid crystal displays (LCDs). IPS modifies the liquid crystal behavior of an LCD to produce a sharper, more accurate image. Because of this technique, IPS displays can provide a higher quality viewing experience than other screen types such as TN or VA.

IPS technology can be found in everything from televisions to computer monitors to wearable devices. IPS displays are screen types that are part of the LCD panel family. VA and TN are the other two types.

What is IPS

IPS Function

When a voltage is applied to the liquid crystals inside an LCD, the crystals rotate parallel (or in-plane), allowing light to pass through them easily. The final image on the screen will be much clearer if the amount of interference in the light produced by the display is reduced.

Advantages of IPS Display Monitors

One of the most significant advantages of IPS is its ability to deliver wide angles while preserving colors and contrast. This means that an IPS screen can be viewed from nearly any angle and still provide an accurate representation of the image on-screen. Colors on an IPS display will not be washed out or distorted when viewed from an angle, as they would on a TN or VA LCD screen.

In comparison to TNs or VAs, IPS display screens and monitors provide the best quality in a variety of environments (direct sunlight, low light, indoors, or outdoors). Click here for 6.0 Inch Mipi Lcd Display.

Why Should You Use an IPS Display/Monitor?

IPS displays provide wide horizontal and vertical viewing angles, accurate color representation, and visibility in direct sunlight.

1. Maximum Viewing Angles

TN LCDs frequently struggle to display accurate images from a wide range of viewing angles. When viewed from different angles, IPS LCDs virtually eliminate all color distortion and fading.

2. Accurate Color Representation

In-plane switching is a powerful technology that produces the most vivid, true colors available on any TFT LCD. Over 16 million colors can be produced by IPS.

3. Exposure to direct sunlight

The best image quality under direct sunlight is achieved by combining a powerful LED backlight with unparalleled viewing angles. In bright sunlight, IPS displays produce higher-quality images than TN LCDs or OLED displays.

Disadvantages of IPS Display

Some of the disadvantages of an IPS display/monitor include price, contrast, and power consumption. There are some disadvantages to consider before purchasing an IPS display or monitor:

1. Energy Consumption

IPS LCDs consume approximately 15% more power than standard TN LCDs. Because OLED displays do not require a backlight, they consume far less power than IPS displays. If you need an energy-efficient display, LCD IPS technology is not the best option. For a low-power solution, an OLED or TN TFT is preferable.

2. Price

IPS displays are more expensive to manufacture due to their newer and more advanced technology. A TN LCD would be a better choice for a more cost-effective solution.

3. Contrast

IPS displays improve viewing angles and color reproduction significantly, but they lack the contrast capabilities of some competing display types. OLED displays can deliver true black by completely turning off their active pixels, resulting in significantly higher contrast than IPS displays. If you want maximum contrast in your display, an OLED display is the way to go.

As IPS technology advances, it will be integrated into more display applications. Because of in-plane switching's ability to increase viewing angles while maintaining color accuracy, LCDs can compete with high-contrast images found on OLED displays. If you don't need the fastest refresh rates and don't mind a slightly higher power consumption, an IPS display will be a huge asset to your project.

The IPS Technology

When a voltage is applied to the liquid crystals inside an LCD, the liquid crystal rotates in parallel (or in-plane), allowing light to pass through rather than turn upright. This crystal behavior significantly improves many viewing aspects of the display. IPS is superior in color and viewing angles to standard TN panels, and these TFTs can even handle direct sunlight due to their high brightness.

Both linear polarizing filters have transmission axes that point in the same direction. The inner surfaces of the glass plates are treated to align the bordering liquid crystal molecules at a right angle to obtain the 90-degree twisted nematic structure of the liquid crystal layer between the two glass plates without an applied electric field (OFF state). Because the electrodes are arranged in the same plane and on a single glass plate, they generate an electric field that is essentially parallel to the plate.

Liquid crystal molecules exhibit positive dielectric anisotropy and align with their long axis parallel to an applied electrical field. When the polarizer is turned off, the entering light is linearly polarized. The twisted nematic liquid crystal layer rotates the passing light's polarization axis by 90 degrees, ensuring that no light passes through a polarizer. When a sufficient voltage is applied between the electrodes, a corresponding electrical field is generated, realigning the liquid crystal molecules and allowing light to pass through a polarizer.
