A Direct LED (DLED) TV utilizes a specific type of backlighting technology where LEDs are positioned directly behind the entire screen surface. This differs significantly from other LED TV types, such as edge-lit models.
Understanding Direct LED Technology
The core of Direct LED technology lies in the placement of the light-emitting diodes (LEDs). Instead of being located along the edges of the display, as in edge-lit LED TVs, the LEDs in a DLED TV are spread out uniformly across the back panel, directly beneath the LCD screen.
According to information dated 01-Oct-2024, DLED or Direct LED technology refers to the backlighting used in certain TV models to create clearer and more vivid images. This method allows for more precise control over illumination across different zones of the screen.
Benefits of Direct LED Backlighting
The direct placement of LEDs offers several key advantages that contribute to image quality:
- Even Lighting: Because the LEDs are spread across the entire back panel, the light is distributed more uniformly across the screen. This helps to prevent brighter spots or darker corners often seen in edge-lit displays.
- Improved Contrast: The ability to control the brightness of localized groups of LEDs (a feature often called "local dimming" in more advanced DLED sets) allows dark areas to remain dark while bright areas stay bright. This significantly boosts the perceived contrast ratio. The reference states, "Unlike edge lit LEDs, DLED TVs have LEDs positioned directly behind the screen, providing even lighting and improved contrast."
- Clearer and More Vivid Images: As highlighted by the reference, this technology is used to create clearer and more vivid images. The combination of even lighting and enhanced contrast contributes to a richer and more lifelike picture.
DLED vs. Edge-Lit LED
The primary distinction, as mentioned in the reference, is the placement of the LEDs.
| Feature | Direct LED (DLED) | Edge-Lit LED |
|---|---|---|
| LED Placement | Directly behind the screen, spread out | Along the edges of the screen |
| Lighting Uniformity | Generally more uniform | Can sometimes have brighter edges |
| Contrast | Potential for higher contrast (with local dimming) | Generally lower contrast than DLED with local dimming |
In summary, Direct LED technology is a backlighting method that positions LEDs directly behind the screen to improve picture quality through more uniform lighting and enhanced contrast.
