Embodiment Construction

[0045] The invention provides a display device and a backlight module contained therein. The display device preferably includes involuntary display panels such as liquid crystal display panels or electrophoretic display panels; and preferably can be applied to computer monitors, televisions, monitors, and vehicle hosts. In addition, the display device can also be applied to other electronic devices, such as display screens of mobile phones, digital cameras, and handheld game devices.

[0046] exist figure 1 In the illustrated embodiment, the display device includes a display panel 30 and a backlight module 10 . The display panel 30 is stacked on the backlight module 10 to receive light from the backlight module 10 . The backlight module 10 includes a light source device 100 , a reflective curved surface 300 and a cavity 500 . Such as figure 1 and figure 2 As shown, the light source device 100 includes a carrier substrate 110 and a plurality of light sources 130 . In thi...

Abstract

The invention provides a backlight module and a display device comprising the same. The backlight module includes a light source device, a refection curve face, a cavity and a barrier board. The lightsource device comprises at least one light source distributing along the first direction. The reflection curve face extends in the first direction and inner pits are formed in a cross section perpendicular to the first direction, being opposite to the light source. The reflection curve face has a first end and a second end opposite to each other. The first end extends towards the light source device while the second end and the light source device define a light outlet. The cavity is provided with a light receiving end facing the light outlet so as to receive light beams reflected by the reflection curve. The barrier board is arranged between the light sources and a light receiving face of the cavity so as to reduce light beams reflected by the reflection curve face and thus arriving thelight receiving face of the cavity.

Description

technical field [0001] The invention relates to a backlight module with a reflective curved surface and a display device using the backlight module; specifically, the invention relates to a backlight module with a stepped reflective curved surface and a display device using the backlight module. Background technique [0002] Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and so on. However, with the continuous improvement of specification requirements such as resolution and narrow bezel, the optical design in the display device is also tested. [0003] Taking a liquid crystal display device as an example, its optical performance is usually closely related to the backlight module disposed behind the display panel. Traditionally, backlight modules can be roughly divided into two types: edge-lit and direc...
