Backlight modules

Generally speaking, Backlight modules can be divided into Front light and Backlight, while Backlight modules can be classified according to the orientation of the lamp according to their size.

1. Edge-lit

Edge lighting on the side of the single light source, adopt injection molding of light guide plate plan without printing type, often used in medium and small scale under 30 inches of backlight modules, its side of the incident light source planning, the characteristics of light weight, thin, narrow frame, low-power characteristics, also for phones, tablets, laptops illuminant, also has a large scale selection of edge-lit TV backlight module.

Side back into the type of LED light source: this kind of LED back light will highlight ultra-thin energy-saving, compared to a back light technology, on the side into the type of back light technology for the requirement of the overall system design and integration capability can appear slightly higher, but also because of its high overall system integration is what makes it the entire fuselage can appear thin many, more thin side into the type of LED back light volume and a highlight of the side into the type of LED TV. However, from the perspective of manufacturing cost alone, the adoption of side-in white LED technology should consider the need for the complete machine to be light and light, which often results in the increase of costs in many aspects. Therefore, the cost of the whole machine will be higher than that of the straight-down white LED products.

2. Straight down type

For the super-scale backlight modules, the side-light structure is no longer able to take advantage in terms of components, power consumption and Brightness, so the straight-down structure without light guide plate and with the light source placed directly below has been developed. Light source by the spontaneous light sources (such as lamp, LED, etc.) after lending by reflection plate, positive after the diffusion plate evenly divided up, due to settle the space greatens, tubes can be applied in accordance with the TFT Panel Size, but also increased with the thickness of the module, weight, power consumption, the advantages of micromixer mixing effect degrees, good light Angle, light use efficiency is high, the structure should be, etc

Straight down LED backlight: This kind of backlight focuses on picture quality. Therefore, many enterprises adopting straight down LED backlight technology have higher requirements for picture quality. The reason why straight-down LED backlight can fully guarantee the picture quality is that it evenly places multiple LED light sources on the backlight panel in a scientific arrangement, so that the backlight can uniformly transmit the color to the whole screen and make the picture details appear delicate and realistic. In addition, LED backlighting divides its elements into cells, and each cell has its own color control correction to accurately present the image and display extraordinary color and shade contrast effects.
