Abstract
The invention discloses a backlight module, which comprises a plurality of linear light sources, at least two lamp slots, a lower reflecting plate, an upper reflecting plate and a module framework. The lamp slots are arc-shaped, the linear light sources are respectively arranged in the lamp slots, adjacent lamp slots are arranged back to back, the openings of the lamp slots on the edges are arranged inwards, and a light transmission plate has certain light transmittance and light reflectance; the lower reflecting plate is arranged under the lamp slots and is used for selectively reflecting light; the upper reflecting plate is arranged above the lamp slots and is used for selectively transmitting light; and the module framework is used for accommodating the linear light sources, the lamp slots, the lower reflecting plate and the upper reflecting plate. The light and thin novel framework type backlight module design is adopted in the backlight module, and the backlight module can be applied in large-sized flat panel displays.
Description
technical field [0001] The invention relates to a backlight module and a liquid crystal display using the backlight module. Background technique [0002] Existing flat-panel displays mostly use TFT-LCD display technology. TFT-LCD is a non-active light-emitting display, which must be matched with a stable backlight module (Backlight Module) to provide uniform system brightness in order to obtain excellent display effects. The backlight module outputs a planar light source with uniform light intensity through the arrangement of light-emitting components, matching of optical components and internal mechanism design. According to the arrangement of light-emitting components, it is mainly divided into two types: direct-type backlight module and side-type backlight module. The schematic diagram is as follows: Figure 1 is the structure of side-type backlight module; figure 2 It is a direct type backlight module structure. [0003] The traditional side-type backlight module needs...
