Document Type and Number:
WIPO Patent Application WO/2024/065479
Kind Code:
A1
Abstract:
A backlight module (10), comprising a backplane (1), a light source (2), an optical diaphragm set (3), and a middle frame (4). The backplane (1) comprises an inner bottom frame (11) and a plurality of inner side frames (12), the plurality of inner side frames (12) of and the inner bottom frame (11) of the backplane (1) forming a first accommodating space (R1). The inner bottom frame (11) of the backplane (1) comprises a first surface (11a), a second surface (11b) opposite thereto, and a plurality of side surfaces connecting the first surface (11a) to the second surface (11b). The plurality of inner side frames (12) of the backplane (1) are correspondingly connected to the plurality of side surfaces of the inner bottom frame (11), and extend to one side of the first surface (11a) of the inner bottom frame (11). The light source (2) is arranged in the first accommodating space (R1). The optical diaphragm set (3) is arranged in the first accommodating space (R1). The middle frame (4) comprises a fixing portion (41) surrounding the plurality of inner side frames (12) of the backplane (1), the plurality of inner side frames (12) of the backplane (1) being connected to the fixing portion (41) of the middle frame (4). The backplane (1) comprises a plurality of inner corners (13) formed by the plurality of inner side frames (12) and the inner bottom frame (11), and the fixing portion (41) of the middle frame (4) comprises outer corners (43) correspondingly matched with the inner corners (13). Fool-proof structures are provided at least at the inner corners (13) of the backplane (1) and the outer corners (43) of the middle frame (4), the fool-proof structures being used for distinguishing between the mounting directions of the backplane (1) and of the middle frame (4).
