[Implementation] In order to make it easy for your examiner to understand the other features, content and advantages of this creation and the effect achieved, it will be more obvious. 'I will combine this creation with the accompanying drawings, as follows: Please refer to Figure 2, The invention provides a high-brightness surface light source device, which includes a plurality of light sources 1, a reflecting plate 2, a light guide plate 3, a first light collecting plate 4, a second light collecting plate 5, a protective sheet 6, and a liquid crystal panel 7. , Characterized in that: the plurality of light sources 1 (such as: light emitting diodes, light bulbs, cold cathode tubes or related line light sources, etc.) are used to emit light beams; and the plurality of light sources 1 are provided with a light source cover 1 0 on one side. The cover 10 series partially surrounds the plurality of light sources 1;

..Page 7 M254614 ί !, creation instructions (3) the utilization rate of the bottom surface of the reflective light plate 3; the light guide map 4), and its surface is formed by, electroformed,, the bottom surface 3 3 1 of Diffusion such as: ring-shaped, diffuse dots 3, when the de-beam reflects the first light collecting plate 4 and the refractive index of 41, the second micro-diaphragm 5 can be used to improve the directivity of the second micro-diaphragm. The beam expansion 2 is provided with points 3 1 1 prismatic, three 21, and dot shadows, and the light collecting plate 4 is provided with a plurality of and spotlights as a front-brightness light collecting plate 5 1. On the side, the fascia panel 7 is a plate 3 with a smooth surface. The light guide plate 3 is provided with a light matte super-precision plus plate 2 and is placed below the light guide plate 3. The exposed light is reflected back to the light guide plate 3. In order to cooperate with the printing industry, etc.) loose surfaces, multiple densifications, angles, etc. can be controlled for access to the micro system, the purpose of which is relative to the multiple reflections and high fronts are set to protect the installation. For brushing or non-expansion, the size of the diffuser network is not). The light beam is high on the front side of the light guide sheet 4 1 to increase the refraction and brightness of the micro-preserving lens; the second set of edge liquid crystals, the protective plate surface 3 1, the printed scattered point 3, and the light plate 3 3 2 1 are emitted from the same expanded bottom surface. The brightness of the plate 3, by the light-shielding sheet or wedge-shaped 'the way out (1 1 (set one, by the angle of the scatter point Figure 3 2 angle purpose; the square beam side of the complex beam 51 1 refractive index reached One more side of the multiple micro-prism panel 7 provided by the light plate 5 is added; the side of the sheet 6 is a plate that will raise the light beam from the guide (such as smooth surface 3 1 such as: I engraved as shown in Figure 3) bottom surface 2 2 the light Case design (set a plurality and simultaneously reach one side, and the first microprism sheet is directional and also provided with a plurality of and a light beam to make a beam of light

4. Description of creation (4) Display device; please refer to the second and third figures again, a reflecting plate 2 is provided below the light guide plate 3, and a first light collecting plate 4 is directly installed above the light guide plate 3. A second light collecting plate 5 is installed above a light collecting plate 4, and a protective sheet 6 is placed above the second light collecting plate 5. A liquid crystal panel 7 is placed above the protective sheet 6. Way, the light beam is allowed to enter the light guide plate 3 ′ and the light beam exposed from the bottom surface of the light guide plate 3 is reflected back to the light guide plate 3 with the aid of the reflection plate 2, so as to increase the utilization rate of the light beam and the light guide The plural diffusion points 3 2 1 of the bottom surface 3 2 of the light plate 3 are matched with the guide

The light emitting surface 3 1 of the light plate 3 has a diffusion point 3 1 1 set on the matte surface of the surface, thereby offsetting the shadow of the light beam reflection point, and achieving the purpose of uniform light emission and simultaneously improving the frontal degree of immunity ', and the light beam emitted through the light emitting surface 3 1 The plurality of micro-diaphragms 41 provided in the first light-collecting plate 4 directly generate a refractive effect, and then pass through the plurality of micro-prisms 5 1 provided in the second light-collecting plate 5 to further reflect and refract the light beam for a long time.俾 Da again increased the directivity of the outgoing light beam, and then improved the brightness of the front. This shows that this creation is extremely practical and progressive; 〃

In order to make this creation show its progressiveness and practicability, a comparative analysis with conventional usage is as follows: Absence of conventional usage 1. Due to the effect of the diffuser plate, the directivity of the light beam is poor. 2. The front brightness is relatively reduced. 3. The manufacturing cost is too high.
