Embodiment Construction

[0018] Next is the detailed description of the present invention. The description of the planar light source device in the following description does not include the detailed component composition and the principle of actual driving operation. The prior art used by the present invention is only focused here. Cited to help explain the present invention. Moreover, the relevant illustrations in the following texts are not drawn according to the actual scale, and their function is only to express the characteristics of the present invention.

[0019] A preferred embodiment of the present invention is to provide a front substrate structure suitable for a planar light source device. Referring to FIG. 3A, the rear substrate 303, a plurality of electrodes (not shown in the figure), the surrounding frame 305, the dielectric layer 311, and the fluorescent layer 313 in the planar light source device 300 are composed of the same components as those described in the prior art. However, in...

Abstract

The front base board structure for planar light source device is one integrally formed raised curved surface structure or one integrally formed outer convex and inner concave structure. The front base board structure has the function of support frame and can diffuse the light the planar light source device generates homogeneously.

Description

technical field [0001] The invention relates to a structure of a planar light source device, especially a front substrate structure in the planar light source device, which not only has the function of supporting, but also allows the planar light source device to have a uniform light output. Background technique [0002] The structure of an existing planar light source device 100 can be referred to in FIG. ) 105 to form a mezzanine space. The front substrate 101 can be called the upper substrate, which is placed in the light output direction of the planar light source device 100, and is composed of a glass or other polymer material, and has light transmission; the rear substrate can be called the lower substrate, And it can also be made of materials such as glass. [0003] In this interlayer space, at first, a plurality of anode electrodes 107 and cathode electrodes 109 are arranged on the surface of the rear substrate 103, and a layer of dielectric layer 111 is coated on ...
