Embodiment Construction

[0036] The invention provides a backlight module, which is mainly composed of a light guide plate and a light source module. The light guide plate has a first side and a second side tangent to the first side. The light source module is arranged beside the first side and the second side of the light guide plate, and the light source module is respectively arranged with a plurality of first light emitting diode units and a plurality of second light emitting diode units facing the first side and the second side of the light guide plate. diode unit.

[0037] In an embodiment of the present invention, the above-mentioned backlight module may further include a LED driving module. The LED driving module is coupled to the light source module and can control the brightness of the first LED unit and the second LED unit respectively. According to the above, the light guide plate can be divided into a plurality of sub-regions according to the relative positional relationship between the...

Abstract

The invention discloses a backlight module and a liquid crystal display using the backlight module. The backlight module comprises a light guide plate and a light source module. The light guide plate comprises a first side and a second side tangent with the first side. The light source module is configured beside the first side and the second side of the light guide plate; and a plurality of first light emitting diode units and a plurality of second light emitting diode units are respectively configured on the light source module facing toward the first side and the second side of the light guide plate. Therefore, the backlight module has the advantages of high image contrast of the direct type backlight module and electricity conservation, and the thickness of the side backlight module is kept.

Description

technical field [0001] The invention relates to a light source module, and in particular to a backlight module and a liquid crystal display using the backlight module. Background technique [0002] As far as current display devices are concerned, liquid crystal display devices with characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have become mainstream in the market. Liquid crystal displays have been widely used in the display screens of consumer electronic products such as televisions, smart phones and notebook computers. However, since the liquid crystal display panel itself does not have the function of emitting light, sufficient light sources must be provided behind the liquid crystal display panel so that the liquid crystal display panel can achieve the purpose of displaying images. [0003] There are roughly two types of backlight modules used in liquid crystal displays: direct-type backlight module...
