What is WOLED Panel?
WOLED (White OLED) is a type of OLED (Organic Light Emitting Diode) technology where the OLED panel emits white light instead of colored light directly. The emitted white light is then passed through color filters (usually red, green, and blue) to produce a full-color image.
WOLED is primarily used in high-end TVs and displays, offering exceptional picture quality, vibrant colors, and deep blacks. In WOLED technology, the OLED material is designed to emit white light, which is then filtered into RGB colors. The white light source helps improve the overall brightness of the display, allowing for higher peak brightness levels compared to conventional RGB OLED displays. By using white light, WOLED panels are more energy-efficient than traditional OLED panels. The efficiency is improved because the need for generating individual red, green, and blue light emissions is reduced. Despite using white light, WOLED panels can still deliver excellent color accuracy and vibrancy due to the high-quality color filters and precise control over each pixel. They can achieve a wide color gamut, often covering near 100% of the DCI-P3 color space. Similar to traditional OLED, WOLED panels are capable of producing true black levels, as each pixel can be turned off independently, allowing for a level of contrast that is unmatched by most other display technologies (such as LCD or LED). Since OLED displays, including WOLED, do not require a backlight (unlike LCD panels), they can be made incredibly thin, allowing for sleek, ultra-thin displays. WOLED displays typically offer wide viewing angles with consistent brightness and color saturation even when viewed from the side.
