Learn about backlight applications
The so-called backlight should be a light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. The liquid crystal display itself does not emit light. The graphics or characters it displays are the result of its modulation of the optical fiber, which has become the initial stage of the development of the backlight source. Now the backlight source has become an independent electronic discipline, and has gradually become a research and development hotspot.

Analysis of advantages and disadvantages of edge-type LED backlight
As a kind of backlight product of common technology, edge-lit LED backlight source is also known as one of two broad LED backlight sources, just like direct-lit LED backlight source. What are the characteristics of the side-mounted LED backlight, and what are the advantages and disadvantages, here we make a unified analysis.

The difference between direct type LED backlight and edge type LED backlight and which one is better
1. The direct-type LED backlight has a simple process and does not require a light guide plate. The LED array is placed at the bottom of the light box. The light emitted from the LED is reflected from the bottom and side surfaces, and then evenly emitted through the diffuser plate and optical module on the surface. 2. The thickness of the direct-type LED backlight is determined by the distance between the bottom of the light box and the diffuser. Usually, the thicker the thickness, the better the light uniformity of the LED backlight. In the case of thin LED backlights, color and brightness uniformity have become the technical key to direct-lit LED backlights. 3. Most of the direct-type LED backlights use edge-emitting LEDs, but the large-angle edge-emitting LEDs are prone to dark spots due to the low light intensity in the middle, which affects the uniformity of the LED backlights.
