There are differences and similarities between the LED backlight display using IPS technology and the Liquid Retina display in many aspects. The following is a detailed analysis of the two:
IPS LED backlight display
Technical features:
IPS technology: IPS, or plane switching technology, is a liquid crystal display technology. It achieves a wider viewing angle, higher color reproduction and more stable dynamic performance by optimizing the arrangement of liquid crystal molecules.
LED backlight: Using the LED backlight system, the light is emitted by the LED lamp beads, and after modulation by the light guide plate and the diaphragm, the light emitted by the entire backlight surface is evenly distributed.
Advantages:
Wide viewing angle: The IPS LED backlight display has a wide viewing angle of 178 degrees. No matter from which angle you watch the screen, you can get a clear and stable picture effect.
High color reproduction: It can present a more realistic and full color effect, suitable for graphic design, film and television post-production and games.
Stable dynamic performance: It can present a smooth and shadow-free picture effect, suitable for sports event broadcasts, game competitions and other scenes.
Long life and energy saving: It has a long service life and energy-saving characteristics, which can reduce maintenance costs and energy consumption.
High definition and low glare: It can present a more delicate and clear picture effect, while reducing reflection and glare, and improving viewing comfort.
Liquid Retina Display
Technical features:
Liquid Retina technology: It is a display technology of Apple that combines high resolution, high color accuracy and high brightness.
Multiple backlight technologies: Liquid Retina display may use LED backlight (such as iPad 10) or more advanced mini-LED backlight (such as Liquid Retina XDR display on iPad Pro).
Advantages (taking iPad 10 as an example):
High resolution: 10.9-inch Liquid Retina display, with a resolution of 2360 x 1640 pixels and a pixel density of 264 ppi, provides a clear and delicate picture.
Color accuracy: Supports True Tone display technology, which can adjust the screen color temperature according to the ambient light to make the image look more natural.
Brightness and contrast: It has high brightness (such as 500 nits) and contrast, suitable for viewing in different lighting environments.
Anti-oil and anti-fingerprint coating: The screen surface is coated with an anti-oil and anti-fingerprint coating to keep the screen clean and reduce fingerprint residue.
Advanced version (such as Liquid Retina XDR display on iPad Pro):
Extreme dynamic range: Supports high contrast and high brightness, capable of displaying extremely bright highlights and subtle details in the darkest parts of the image.
ProMotion adaptive refresh rate: Automatically adjusts the refresh rate of the display to up to 120 Hz, providing ultra-smooth scrolling experience and responsiveness.
Ultra-high brightness and contrast: Under certain conditions, the Liquid Retina XDR display can support up to 1,600 nits of high light brightness and a contrast ratio of up to 1,000,000:1.
Summary
LED-backlit displays with IPS technology and Liquid Retina displays perform well in many aspects, but Liquid Retina displays may have higher standards in terms of color accuracy, brightness, contrast, and dynamic performance, especially in Apple's high-end products (such as iPad Pro). However, for general users, LED-backlit displays with IPS technology are sufficient for daily use and entertainment needs.
