摘要： The present invention discloses a backlight module having a light guide plate and a plurality of backlight sources. The light guide plate contains a plurality of grooves which divide the light guide plate into several domains. All of the grooves have a specific cross section which may be triangular, trapezoidal, or convex curved in shape. The light guide plate can reflect light emitted by the backlight sources through specific angles resulted from the specific cross sections of the grooves. Therefore, it is entirely possible to achieve the target of local dimming of the backlight module by means of a design of positions of the grooves and of angles of the cross sections.
摘要翻译：本发明公开了一种具有导光板和多个背光源的背光模块。导光板包括将导光板分成多个区域的多个凹槽。所有凹槽都具有可以是三角形，梯形或凸形弯曲形状的特定横截面。导光板可以通过由凹槽的特定横截面产生的特定角度反射由背光源发射的光。因此，完全可以通过凹槽的位置和横截面的角度的设计来实现背光模块的局部调光的目标。

摘要： A backlight module capable of dynamically adjusting brightness is proposed. According to the present invention, a backlight module comprises a light guide plate for guiding light, a first light source unit, and a second light source unit. A ridge-shaped groove is disposed on the middle of the bottom surface of the light guide plate. The first light source unit and the second light source unit are respectively disposed at the opposite sides of the light guide plate. Both of the first light source unit and the second light source unit comprises at least one light source. Each of the light sources of the first light source unit is symmetrically arranged with each of the light sources of the second light source unit on a one-on-one basis. The ridge-shaped groove divides the backlight module into two independent luminance domains, each dividing into multiple subdomains. Actual luminance of each subdomain is adjustable based on its predetermined brightness and distributions, reducing power consumption and enhance an image contrast.
