Title: OPTICAL DIAPHRAGM, BACKLIGHT MODULE, AND DISPLAY APPARATUS
Abstract:
An optical diaphragm (25), a backlight module, and a display apparatus. The optical diaphragm (25) comprises an upper surface, a lower surface, and multiple side surfaces located between the upper surface and the lower surface. Multiple microstructures (20) are at least disposed on the side surface close to a light source, and are used for deflecting and scattering incident light. The problem of uneven light emission due to light gathering at a gap between an optical diaphragm of a backlight module and a lamp bar (10) is solved.
