Title:
DIRECT TYPE BACKLIGHT MODULE AND DISPLAY
Document Type and Number:
WIPO Patent Application WO/2019/037356
Kind Code:
A1
Abstract:
A direct type backlight module and display. The direct type backlight module comprises a first reflective sheet and at least one second reflective sheet. The second reflective sheet is disposed at the inner side of the vertex angle of the first reflective sheet, and the reflective surface of the second reflective sheet is connected to the reflective surface of the first reflective sheet. The reflectivity of the reflective surface of the second reflective sheet is higher than the reflectivity of the reflective surface of the first reflective sheet. By providing the second reflective sheet having a higher reflectivity in a corner region where the light intensity of the direct type backlight module is lower, the light intensity at the corner position of the direct type backlight module can be improved; and thus the vignetting problem of the direct type backlight module can be avoided, thereby improving the uniformity of images of a display device corresponding to the direct type backlight module.
