Description

Technical Field

[0001] The utility model belongs to the technical field of glass, and in particular relates to a structure for solving the uneven local light color and color temperature of a QD glass diffusion plate. Background Art

[0002] Blue LED with quantum dot film (QD film) can achieve high color gamut, making the display color richer and the color saturation higher. The light-distributing component in the backlight module can convert the point light source of the LED into a surface light source distributed over the entire surface. In large-size displays, the optical uniformity is usually required to be above 75%, and high-end products may require a uniformity of more than 85%. The light at the position of the light-distributing component facing the LED lamp beads is still relatively concentrated, and the backlight design usually requires the brightness trend to gradually weaken from the center of the backlight module to the periphery, and the center brightness is required to be 10-20% higher than the edge. This has less impact in conventional white LED backlight modules, but in blue LED backlight modules, when the blue light is concentrated, the proportion of light converted into white light through the QD film is reduced, and the proportion of blue light penetration is increased. This causes the color temperature of the position facing the LED in the backlight module to be low, while the color temperature of other positions is high, and there may even be local bluish and yellowish visible to the naked eye, affecting the display effect, and also causing certain damage to the human eye. Utility Model Content
