Abstract

A backlight module comprises a light guide plate, at least one first light source and at least one second light source. At least one first light inlet surface and at least one second light inlet surface are alternatively distributed at a light inlet side of the light guide plate, and the first light inlet surface and the second light inlet surface form a separation angle. The first light source is arranged at the position adjacent with the first light inlet surface and the light beam emitted from the first light source is suitable for advancing towards the left half part of the light guide plate; the second light source is arranged at the position adjacent with the second light inlet surface and the light beam emitted from the second light source is suitable for advancing towards the right half part of the light guide plate, and the first light source and the second light source alternatively twinkle.

Description

technical field [0001] The invention relates to a backlight module and a display device with two different light-emitting viewing angles. Background technique [0002] Figure 10 It is a schematic diagram showing a prior art display device with two different light output viewing angles. like Figure 10 As shown, the display device 100 includes a light guide plate 102 , a right light source 104 , a left light source 106 , a prism sheet 108 and a display panel 110 . The right light source 104 and the left light source 106 are turned on alternately, and the prism sheet 108 deflects the light beams from the right light source 104 and the left light source 106 to the left and right respectively, so that the observer's eyes receive different light beams respectively. The light at the angle of light is used to produce a stereoscopic effect. However, according to the light emitting method of the above-mentioned existing design, the bottom side of the light guide plate 102 needs to...
