Problems solved by technology

[0004] In order to get rid of the rigid and dull image of the current display device, manufacturers design products by setting a light source on the display device to attract consumers, but if one light source is installed, the decorative effect will be poor. Considering the positional relationship and connection relationship between the light source and the display device increases the difficulty of design

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] Please also refer to figure 1 and figure 2 The display device 30 provided by the first embodiment of the present invention includes a plurality of light emitting diodes 110, a circuit board 12 electrically connected to the plurality of light emitting diodes 110, a focusing lens unit 13, a plurality of bundles of optical fibers 140, a fixing member 15 and a ring guide Light Part 31.

[0013] The focus lens unit 13 includes a plurality of focus lenses 130 . Each focusing lens 130 corresponds to one LED 110 and receives the light emitted by the corresponding LED 110 . The function of the focusing lens 130 is to concentrate the light emitted by the LED 110 . Generally, the light-emitting area of ​​the light-emitting diode is larger than the port area of ​​the optical fiber. If the light is not concentrated, the coupling efficiency between the optical ...

Abstract

The invention relates to a display device which comprises a plurality of LEDs, a plurality of beams of optical fiber and a ring-shaped light guide piece, wherein the plurality of beams of optical fiber correspond to the plurality of LEDs one by one; each beam of optical fiber is provided with a first port and a second port; the light emitted by the LEDs enters the first ports of the corresponding optical fiber and is then given out through the second ports; the ring-shaped light guide piece is provided with an inner ring surface which is provided with a plurality of optical coupling parts; the plurality of beams of optical fiber correspond to the plurality of optical coupling parts one by one; and the light given out from the second port of each beam of optical fiber passes through the optical coupling part corresponding to the optical fiber and then enters the light guide piece. The display device has ring-shaped light source and good decoration effect.

Description

technical field [0001] The invention relates to a display device, in particular to a display device with a ring light source. Background technique [0002] Display devices, such as mobile phones, digital music players, personal digital assistants, computers, etc., are becoming more and more popular. [0003] The performance of display devices is generally the primary factor for consumers to consider whether to buy or not. However, in the current situation where product performance is almost equal, product appearance is also an important factor for consumers to consider. [0004] In order to get rid of the rigid and dull image of the current display device, manufacturers design products by setting a light source on the display device to attract consumers, but if one light source is installed, the decorative effect will be poor. Considering the positional relationship and connection relationship between the light source and the display device increases the difficulty of desig...
