LCD
A display technology that emits light through a backlight layer and controls light transmission via liquid crystal molecules; its black reproduction and contrast ratio are comparatively limited.

Traditional LCDs rely on a uniform backlight, and even with Mini-LED local dimming, the halo phenomenon remains difficult to fully avoid.
The cost per unit area of OLED panels is still significantly higher than that of Mini-LED or LCD panels of the same specification.
LCD relies on a backlight layer to emit light, and the liquid crystal molecules are only responsible for controlling whether light passes through.
The mainstream technical path for implementing touch on laptops is to overlay a touch-sensing layer (such as an on-cell or in-cell structure) on an LCD or OLED panel, which increases panel thickness, cost and power consumption, and may affect screen brightness and color accuracy.
OLED panels and LCD panels differ fundamentally in how they work: LCD relies on a backlight module to illuminate the liquid crystal layer to form an image, whereas each pixel of an OLED can emit light and switch off independently.
Mini-LED is still essentially LCD; it divides the traditional LED backlight into hundreds or thousands of independent dimming zones, improving contrast through local dimming.
With the arrival of the LCD era, the burn-in problem disappeared, and operating systems began replacing screensavers with turning off the screen backlight as an energy-saving solution.
LCD panels may exhibit brightness flickering at low refresh rate ranges in VRR mode, and the industry commonly employs LFC technology to keep the refresh rate within an acceptable range through frame doubling.
Each OLED pixel emits its own light, and when a pixel is turned off the area emits no light at all, making it visually indistinguishable from physical black; LCD requires a backlight module and cannot achieve true pure black.
The blue light peak wavelength of LCD screens is concentrated in the 430–450 nm range, and the PWM flicker frequency of some OLED panels is as low as 240 Hz
