Embodiment Construction

[0045] The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only directions referring to the attached drawings. Accordingly, the directional terms are used to illustrate and not to limit the invention. see figure 1 , figure 1 It is a schematic diagram of a backlit keyboard 3000 according to the first embodiment of the present invention. like figure 1 As shown, the backlit keyboard 3000 includes a keyboard part 1 and a backlight structure 2. The keyboard part 1 is disposed on the backlight structure 2. The backlight structure 2 is used to provide a light source for the keyboard part 1, so that the backlit keyboard 3000 produces a visual effect of light.

[0046] see figure 1 , figure 2 , Figure 3A as well as Figure 3B , figure 2 It is an explosion schematic diagram of the backlight structure 2 of the first embodiment of the present invention, Figure 3A for figure 2 A partial cross-sectional schema...

Abstract

A backlight structure comprises a light guide plate, a luminescent unit, a reflecting sheet, a fluid solidification layer and a bonding layer, wherein the light guide plate has an incident surface, a light exit surface, and a bottom and a side surface opposite to the light exit surface, the luminescent unit is adjacent to the incident surface, light emitted by the luminescent unit enters into the light guide plate through the incident surface and is emitted out from the light exit surface, the reflecting sheet is placed under the bottom to reflect light emitted out from the bottom, the fluid solidification layer is arranged on the side surface to prevent light from emitting out of the side surface, the bonding layer is bound between the light guide plate and the reflecting sheet to restrict the scope that the fluid solidification layer can enter when assembled to the edges of the reflecting sheet between the reflecting sheet and the light guide plate.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 31, 2014, an application number of 201410374191.8, and an invention title of "A Backlight Structure Suitable for Illuminated Keyboards and Its Manufacturing Method". technical field [0002] The invention relates to a backlight structure, in particular to a backlight structure capable of preventing edge light leakage. Background technique [0003] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, with the improvement of consumers' visual demands, a luminous backlit keyboard has become a new development direction of the industry. Generally speaking, a backlit keyboard uses a side-lit backlight module as its light source, that is, the light-emitting diode used to emit light is arranged on one side of the light-incident surface of the li...
