In backlight products, light uniformity is a fundamental indicator for measuring display or lighting effects. Wooden soft light board, as a type of diffusion material, is often placed between the backlight and the working surface to improve the distribution of light. Its coordination mainly involves several aspects such as light source layout, spacing control, and material selection.

Backlights are usually composed of LED beads or light strips arranged at a certain distance. If the light source shines directly outward, it is easy to form bright and dark stripes or spots on the working surface. The function of wooden soft light board is to diffuse these discrete light sources for a second time. When light enters the soft light board, the wooden fiber structure will reflect and refract the light multiple times, causing the originally concentrated light energy to disperse in all directions, thus forming a relatively continuous light distribution on the light emitting surface.

The distance between the soft light panel and the backlight is one of the factors that affect uniformity. The spacing is too small, and the light has not fully diffused before passing through the board, resulting in limited uniformity; If the spacing is too large, it may cause a decrease in overall brightness. In practical applications, it is necessary to set the diffusion effect and brightness in a reasonable manner based on the power of the light source, the density of the arrangement, and the transmittance of the soft light plate.

In terms of materials, the thickness and density of wooden flexographic panels directly affect their diffusion ability. Thicker or denser boards have a relatively strong scattering effect on light, which is beneficial for uniform light output, but the transmittance will correspondingly decrease. Therefore, on the premise of meeting the uniformity requirements, it is necessary to select appropriate specifications based on the actual brightness of the backlight source.

In addition, a heat dissipation space should be maintained between the soft light board and the light source to avoid long-term high temperature affecting material stability. During installation, it is necessary to ensure that the board surface is flat to prevent uneven light output due to local warping. Through reasonable arrangement of light sources, spacing design, and material matching, wooden soft light boards can play a relatively stable diffusion role in backlight systems.
