摘要: A backlight module (10) includes a light guide plate (100) and a light source (110). The light guide plate includes a light incident surface (102). The light incident surface includes a plurality of dots (108) provided thereat. The light source is disposed adjacent to the light incident surface. A sum of a size of one dot and a pitch between adjacent dots is less than 380 nm. The backlight module can obtain optimized optical performance.

摘要: A backlight module (3) includes a light guide plate (31), a light source (32) and an optical conversion device (33). The light guide plate includes an incident surface (311), an emitting surface (312) adjacent to the incident surface and a bottom surface (313) parallel to the emitting surface. The incident surface maintains an oblique angle relative to the bottom surface. The light source is near the incident surface of the light guide plate for radiating light beams toward the light guide plate. The optical conversion device is disposed between the light source and the light incident surface, which is configured for transforming a polarization state of some of the light beams received from the light source such that the transformed light beams can enter the light guide plate through the incident surface.

摘要: A diffusion plate (20) includes at least two diffusion units (21), each diffusion unit including at least one connecting portion (23). The connecting portions (23a, 23b) of each two adjacent diffusion units mate with each other, thereby connecting all the diffusion units together. The number of diffusion units may be increased or decreased according to the size of a liquid crystal display to be produced. This eliminates the need to alter the production means for differently sized backlight modules, thereby reducing costs and increasing production efficiency. In another embodiment, a diffusion plate (50) includes at least two diffusion units (51). Each diffusion unit includes at least one connection protrusion (53a). At least one interconnecting member (53) is disposed between each two adjacent diffusion units. The interconnecting member and the connecting protrusions mate with each other, thereby connecting all the diffusion units together. A related backlight module (500) is also provided.

摘要: A liquid crystal display device (4) includes a liquid crystal display panel (41) and a backlight module (2) opposite to the liquid crystal display panel. The backlight module includes a light guide plate (20) and a point light source (21) adjacent to the light guide plate. A horizontal central axis (210) of the point light source and a horizontal central axis (200) of the light guide plate are on a same plane. The backlight module can further comprises a prism sheet, a diffusing sheet, a reflective sheet, and/or a polarizer. The liquid crystal display device can provide a uniform display effect.
