Abstract

The invention discloses a backlight module which comprises a light guide plate, a plurality of light emitting elements and a positioning element. The light guide plate comprises a light incoming side and an upper surface which intersects at the light incoming side; the light emitting elements have light emitting angles and are arranged in the range of the light emitting angles and respectively project light to the light incoming side, and the light forms a plurality of dark zones at the position of the light guide plate beyond the range of the light emitting angles; and the positioning element comprises a plurality of protruding parts which protrude to the upper surface and respectively support against the dark zones. The invention also discloses a flat panel display and a design method of a positioning element of the same.

Description

technical field [0001] The invention relates to a backlight module, in particular to a design method of a backlight module capable of improving luminance uniformity, a flat panel display and a positioning component thereof. Background technique [0002] With the rapid progress and evolution of display technology, the traditional cathode ray tube (cathode ray tube, CRT) has been gradually eliminated due to problems such as poor space utilization and large energy consumption, and has been replaced by light, thin, short, small LCD (liquid crystal display, LCD). Due to the advantages of high display quality, low energy consumption and no radiation, liquid crystal displays are widely used in notebook computers, computer screens, mobile phones, personal digital assistants (PDAs), digital cameras, digital Among communication, information or consumer electronics products such as cameras and LCD TVs. [0003] Liquid crystal displays mainly use liquid crystal panels for display. Sin...
