Differences between Window LCD Display and OLED LCD

Window LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode) are two mainstream display technologies, with significant differences in their light-emitting principles, display effects, and application scenarios. Below is a detailed comparison:

Light-Emitting Principles and Structural Differences

LCD
Relies on a backlight (LED or CCFL) to emit light, controlling the amount of light that passes through through liquid crystal molecules and using filters to create color. Its structure is complex, consisting of multiple layers including a backlight layer, liquid crystal layer, and polarizer, resulting in a relatively high thickness.

OLED
Each pixel emits light independently, eliminating the need for a backlight layer. The organic material emits light directly when powered. This allows for a thinner and lighter structure, enabling flexible designs (such as foldable screens).
