The liquid crystal panel 11 is located in front of the display structure 1 (i.e., to the left of FIG. 1A). The front frame 12 is wrapped around the outer periphery of the liquid crystal panel 11. The interior of the front frame 12 includes an optical channel 123, which may be a space or a solid material of transparent material (for example, glass, acrylic, plastic, resin or other high molecular polymer). Thus, the optical channel 123 can be used to transmit light such that light travels freely within the optical channel 123. The optical channel 123 is provided with a plurality of reflective structures 124 on one side and a half transparent region 125 on the other side. The semi-transmissive regions 125 are from top to bottom and are located at the forefront of the display structure 1 (ie, The reflective structures 124 are located within the semi-transmissive region 125 and spaced apart from the reflective structure 124 by a distance (P). A light source 141 is disposed inside the dark box structure 14 , and the dark box structure 14 is adjacent to the upper end of the optical channel 123 and connected to each other.

The outside of the display structure 1 is emitted, and another portion of the light is reflected back to the reflective structure 124. In this way, the light emitted from the light source 141 can be continuously reflected and refracted along the optical channel 123, so that the light emitted by the entire semi-transmissive region 125 can be uniformly distributed. In general, the light transmittance of the semi-transmissive region 125 is 5% or more, and a better effect can be obtained. Thereby, the front frame 12 of the display structure 1 can transmit the bright light, and then the image video of the liquid crystal panel 11 can be used to simultaneously achieve the best advertising and publicity effects without additional It is very convenient to use a light source or a neon light.

In a preferred embodiment, the light source 141 is preferably a Light Emitted Diode (LED), because the LED is small in size, large in brightness, and relatively power-saving. Thus, the dark box structure 14 is less occupied. space. In addition, the inner surface of the dark box structure 14 can be further attached or coated with the reflective layer 14A. Therefore, the light emitted by the light source 141 can enter the optical channel 123 completely, and the light energy is wasted and consumed. . As previously mentioned, the reflective layer 14A can also be a technical means such as a coated reflective coating, a white skin or an electroplated metal layer, the purpose of which is to increase the ratio of light reflection within the dark box structure 14.

Please refer to FIG. 1A and FIG. 1B simultaneously. FIG. 1B is a perspective view showing the structure of the display according to the first embodiment of the present invention. When the light source 141 is lit, the front frame 12 of the display structure 1 can have a special optical effect by the semi-transmissive region 125 that emits light. The light source 141 may be a color-changing LED or may be mounted in the dark box structure 14 with a plurality of light sources 141 to achieve different color changes. At this time, if the image played by the liquid crystal panel 11 is matched, when the display structure 1 is viewed from the dark, a special effect similar to the "frameless display" can be produced, which is very beautiful.
