Detailed ways

In order to make the above-mentioned purposes, features and advantages of the present utility model more obvious and understandable, the specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings. First of all, it should be noted that the utility model is not limited to the following specific embodiments, and those skilled in the art should understand the utility model from the spirit embodied in the following embodiments, and each technical term can be based on the spirit of the utility model for the broadest understanding. The same or similar components in the figures are denoted by the same reference numerals.

Referring to Figures 1 and 2, the transmissive display device 10 of the first preferred embodiment of the present invention can display a predetermined picture in an illuminated environment, and includes: a light-transmitting reinforcing plate 2, a The liquid crystal component 3 pasted on the light-transmitting reinforcing plate 2 and a frame 4 surrounding the liquid crystal component 3 and the light-transmitting reinforcing plate 2 .

The light-transmitting reinforcing plate 2 is in the shape of a rectangular sheet, and in this preferred embodiment, the light-transmitting reinforcing plate 2 is a transparent tempered glass plate, but it is not limited thereto, and may also be a light-transmitting acrylic resin plate.

However, the liquid crystal assembly 3 of this embodiment includes a light-transmissible liquid crystal unit 31 and a control unit 32 electrically connected to the liquid crystal unit 31 . The liquid crystal unit 31 has two transparent substrate layers 311 parallel and spaced apart, two polarizing layers 312 coated on the outside of the substrate layer 311 respectively, and two polarizing layers 312 coated on the inside of the substrate layer 311 respectively. electrode layers 313 , and a liquid crystal layer 314 sandwiched between the electrode layers 313 .

The thickness of the substrate layer 311 is less than or equal to the thickness of the light-transmitting reinforcing plate 2. In addition, one side of the polarizing layer 312 is pasted on the light-transmitting reinforcing plate 2, that is, the liquid crystal unit 31 and the light-transmitting reinforcing plate 2 The light-transmitting reinforcing plate 2 is combined in an overlapping manner. More specifically, the liquid crystal unit 31 of this embodiment is a liquid crystal display panel, and is attached to the light-transmitting reinforcing plate 2. In addition, the function of the liquid crystal unit 31 Principle and structure are not the features of the present utility model, therefore no further description.

The control unit 32 has a control circuit 321 , several signal cables 322 electrically connected between the control circuit 321 and the electrode layer 313 , and a signal connector 323 electrically connected to the control circuit 321 .

The control circuit 321 of this embodiment is installed on the light-transmitting reinforcing plate 2 and is located below the liquid crystal unit 31. In this preferred embodiment, the control circuit 321 is composed of a control chip and can pass a signal The cable 322 transmits signals to drive the electrode layer 313 to further control the arrangement of the liquid crystal layer 314 , that is, to control the light transmission of each area of the liquid crystal unit 31 . In addition, the signal connector 323 can be plugged into a device such as a personal computer, a digital camera or a handheld device to transmit electrical signals to provide display signals and driving power. It should be added that the method of installing the liquid crystal module 3 on the light-transmitting reinforcing plate 2 is not limited to pasting, and may also be installed by means of erection or clamping.

The frame 4 includes a frame body 41 surrounded by a frame, and a rectangular viewing space 42 adjacent to the center. The frame body 41 is framed on the periphery of the light-transmitting reinforcing plate 2 and the liquid crystal component 3 , and the light-transmitting reinforcing plate 2 and the liquid crystal component 3 are firmly combined and positioned. On the other hand, the see-through space 42 is surrounded by the frame body 41, and the liquid crystal assembly 3 and the light-transmitting reinforcing plate 2 are sandwiched in the frame body 41. In addition, the liquid crystal unit 31 covers The see-through space 42 is not completely covered by the frame body 41 . In addition, the control unit 32 is located in the frame body 41 and is covered by the frame body 41 .

When the transmissive display device 10 is in use, after the signal connector 323 is connected with equipment (not shown) such as a handheld device, a personal computer or a digital camera, the control circuit 321 is driven by a signal, and according to the display signal, The degree of light transmission of each area of the liquid crystal unit 31 is controlled, so that the liquid crystal unit 31 presents different pictures according to the degree of light transmission.

When the transmissive display device 10 is set in an environment with an illumination source, when light passes through the liquid crystal unit 31 through the viewing space 42 of the frame 4, it can transmit light according to each area of the liquid crystal unit 31. The difference in degree shows different gray scales, and highlights the picture that the liquid crystal unit 31 is scheduled to display. Since the liquid crystal unit 31 can transmit light, it shows a semi-transparent picture, so the viewer is viewing the picture on the liquid crystal unit 31. When displaying information, you can see the objects or decorations behind through the liquid crystal unit 31 at the same time to achieve a visual penetration effect. This feature can be effectively used in shopping malls or window decorations, using dynamic images to present product information or decorate the environment. Not only can it provide rich information, but it can also achieve varied and lively embellishment effects. In addition, due to the penetrating feature of the transmissive display device 10 , its placement is more flexible. Since the thickness and strength of the light-transmitting strengthening plate 2 are larger than the substrate layer 311 of the liquid crystal unit 31 , the light-transmitting strengthening plate 2 can support the liquid crystal unit 31 to improve the overall strength.

It is worth mentioning that the size of the liquid crystal unit 31 can be adjusted as needed, and since the light-transmitting reinforcing plate 2 can provide a supporting function to avoid bending and cracking of the liquid crystal unit 31, it is possible to manufacture liquid crystals with larger sizes. When using the liquid crystal unit 31, there is no need to consider the problem of insufficient strength, that is, there is no need to change the structure and manufacturing process of the liquid crystal unit 31, and the production cost can be reduced.

The preferred embodiment of the utility model has been described in detail above, but it should be understood that after reading the above-mentioned teaching content of the utility model, those skilled in the art can make various changes or modifications to the utility model, these equivalent forms Also fall within the scope defined by the appended claims of this application.
