Embodiment Construction

[0044] The invention provides a display device and a backlight module contained therein. The display device preferably includes a non-self-illuminating display panel such as a liquid crystal display panel or an electrophoretic display panel; and is preferably applicable 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.

[0045] 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 As shown, the light source device 100 includes a light source substrate 110 and a plurality of light sources 130 . In ...

Abstract

The invention provides a backlight module and a display device including the same. The backlight module comprises a light source device, a reflection curve and a cavity, whereinthe light source devicehas one or a plurality of light sources distributed in a first direction; the reflection curve extends in the first direction and reflect light rays produced by the reflection light source into the cavity; the reflection curve is provided with a first stage curve and a second stage curve; the first and second stage curves are arranged side by side and extend in the first direction and inwardly recess corresponding to the light source in a cross section perpendicular to the first direction; the second stage curve is more closer to the light source device compared with the first stage curve, and forms a step structure with the first stage curve.

Description

technical field [0001] The invention relates to a backlight module with a reflective curved surface and a display device using the same; in particular, the invention relates to a backlight module with a stepped reflective curved surface and a display device using the same. 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 direct-lit. Among the edge-l...
