Description

Technical Field

[0001] The invention belongs to the technical field of liquid crystal display cabinets, and in particular relates to a liquid crystal display cabinet with a separated polarizer and a display method thereof. Background Art

[0002] LCD display cabinets can display products in 360 degrees in front of people, and every detail of the product can be displayed vividly. It is the most eye-catching projection technology at present. As a high-tech product integrating information processing technology, it breaks the conventional display and develops a more pleasing human-computer interaction, allowing information dissemination to be presented in a more intuitive and clear way, which brings us a lot of fun. Because it can perfectly combine physical objects with multimedia video content, it can attract consumers' attention and achieve better publicity purposes.

[0003] There are three types of products commonly found on the market. One is the traditional LCD display cabinet, such as Figure 1 In the box structure shown, the LCD screen 101 is located at the rear end of the box structure, the front end is placed with tempered glass 102, and the inside of the box is placed with exhibits 103. This type of LCD display cabinet will have the following problems in the process of displaying exhibits:

[0004] 1. Since the LCD screens 101 used for display are all fixed rectangular and cannot be round or other special shapes, the display is relatively simple and cannot be diversified;

[0005] 2. Since there is a relatively large distance between the image displayed on the LCD screen 101 and the exhibits, as well as the tempered glass 102, the user's sense of immersion and experience in viewing the exhibits 103 is relatively far away, and the overall display effect is reduced.

[0006] Meanwhile, the second type of transparent LCD display cabinets available on the market are Figure 2 The box structure shown in the figure has a reflector 201 located at the rear end of the box structure, a transparent LCD screen and tempered glass 202 located at the front end of the box structure, an exhibit 204 located inside the box, and a strong light 203 is provided on the top. Figure 1 This type of structure has the second problem, but there are still other problems:

[0007] 1. Since the LCD screens 202 used for display are all fixed rectangular and cannot be round or other special shapes, the display is relatively simple and cannot be diversified;

[0008] 2. Although the transparent LCD screen 202 that displays images is relatively close to the user, since the liquid crystal itself does not emit light, the LCD screen 202 needs a reflector to support the luminous display image. The transmittance of the liquid crystal is 4%-8%. If the user needs to observe the brightness of about 300nit, the internal backlight source is 300 / 8%=3750nit. Therefore, the strong light inside the box is as high as about 4000nit and the temperature is about 60 degrees. For the exhibits 204 placed in the box, especially valuables, it is easy to cause damage to them; at the same time, when the user opens the window to replace the product, it will feel very dazzling and cannot look directly into the box.

[0009] In addition, the third type of curved LCD display cabinet, such as Figure 3 As shown, a curved liquid crystal screen 301 is used, which is fixedly connected by an upper shell cover 302 and a lower shell cover 303. Although the first problem existing in the above two structures is solved, the design structure is relatively complex and the cost is relatively high.

[0010] In summary, there is an urgent need for a liquid crystal display cabinet that has diversified displays, high immersion and experience, does not cause damage to exhibits, has a simple structural design and is low in cost. Summary of the invention

[0011] In order to solve the above problems, the first purpose of the present invention is to provide a liquid crystal display cabinet with a separated polarizer, which can achieve an immersive and high-experience effect, and has the characteristics of no damage to exhibits, simple structure and low cost.

[0012] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0013] The liquid crystal display cabinet with separated polarizers of the present invention comprises: a cabinet, a backlight source, a liquid crystal module, a control board and a display stand; the liquid crystal module and the backlight source are sequentially located at the rear end face of the cabinet from front to back, and are electrically connected to the control board respectively; the liquid crystal module comprises liquid crystal glass and a first group of polarizers and a second group of polarizers located at the front and rear end faces of the liquid crystal screen; the liquid crystal glass is electrically connected to the control board; the first group of polarizers is located between the backlight source and the liquid crystal glass; the second group of polarizers comprises a second polarizer and a third polarizer; the second polarizer is located between the liquid crystal glass and the display stand, and the third polarizer is located at the front end face of the cabinet.

[0014] Furthermore, the third polarizer is a special-shaped polarizer.

[0015] Furthermore, the special-shaped polarizer is a square polarizer, a circular polarizer or a polarizer of other irregular shapes.

[0016] Furthermore, the cabinet is in the shape of glasses.

[0017] Furthermore, a rotating mechanism is provided at the bottom of the booth.

[0018] Furthermore, the rotating mechanism includes a rotating disc and a motor, and the rotating disc and the motor are driven by gears.

[0019] In order to solve the above problems, the second purpose of the present invention is to provide a liquid crystal display method with a separated polarizer, which can achieve an immersive and high-experience effect.

[0020] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0021] The display method of the liquid crystal display cabinet with separated polarizers of the present invention comprises the following steps:

[0022] A light source having two polarization directions is emitted through a backlight source;

[0023] The light source obtains two groups of unidirectional polarized lights through a first group of polarizers;

[0024] The main control board applies a deflection voltage to the liquid crystal glass containing image information;

[0025] After one group of the unidirectional polarized lights passes through the liquid crystal glass to which the polarization voltage is applied, a single polarized light containing an image is obtained;

[0026] The single polarized light containing the image passes through the third polarizer to obtain an image in which the exhibits on the booth are superimposed with the image information.

[0027] Furthermore, the method further comprises the following steps: during the process of superimposing the exhibit and the image information to form an image, the exhibit rotates at a constant speed.

[0028] Furthermore, the third polarizer is a special-shaped polarizer.

[0029] Furthermore, the special-shaped polarizer is a square polarizer, a circular polarizer or a polarizer of other irregular shapes.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The liquid crystal display cabinet with separated polarizers of the present invention separates the polarizers in the liquid crystal module, specifically moves the third polarizer in the second group of polarizers from between the existing liquid crystal glass and the booth to the front end surface of the cabinet, so that the liquid crystal display image A and the specific exhibits on the booth can be immersively superimposed together, so that the experience effect is better.

[0032] Specifically, the above design structure does not make too many modifications to the existing products. It only adjusts the position of the third polarizer to achieve a better experience effect. The structure is simple and the cost is low. At the same time, there is no need to use strong light, so the temperature inside the box is low (same as room temperature). At the same time, when changing exhibits, there will be no glare when opening the cabinet, because the intensity is only about 600nit, which will not hurt the eyes.

[0033] In addition, the display method of the liquid crystal display cabinet with a separated polarizer described in the present invention adjusts the position of the third polarizer so that the image located on the rear end surface of the cabinet directly appears on the front end surface of the cabinet, thereby making the image and the exhibits well immersed together, making the user experience stronger and enhancing the effect of reality.

[0050] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0051] The liquid crystal display cabinet with separated polarizer of the present invention separates the polarizer by adjusting the specific position of the polarizer, and moves it from between the liquid crystal glass and the booth in the prior art to the front surface of the cabinet, so that the liquid crystal display image and the specific exhibits on the booth can be immersively superimposed together, which is more perfect and harmonious, and the experience effect is better.

[0052] Embodiment 1:

[0053] like Figure 4-7 As shown, the liquid crystal display cabinet with separated polarizer of the present invention comprises a cabinet 1, and the rear end face of the cabinet 1 is provided with a liquid crystal module 2 and a backlight source 3 in sequence from front to back, and is respectively connected with a control board (not shown in the figure). A display stand 4 is provided in the cabinet 1 for placing exhibits. The control board is a prior art, that is, it is used to control the liquid crystal module 2 and the backlight source 3 to emit light and realize according to the set requirements, so as to meet the image display of the exhibits and improve the overall display effect of the exhibits.

[0054] The liquid crystal module 2 includes a liquid crystal glass 21 and a first set of polarizers 22 and a second set of polarizers 23. The liquid crystal glass 21 is electrically connected to the control board. When it is working, after filtering out the light in the X direction or the Y direction, the remaining parallel light is displayed through the polarization of the polarizers so that our naked eyes can see it.

[0055] Specifically, the first group of polarizers 22 is located between the backlight source 3 and the liquid crystal glass 21; the second group of polarizers 23 includes a second polarizer 231 and a third polarizer 232; the second polarizer 231 is located between the liquid crystal glass 21 and the display stand 4, and the third polarizer 232 is located at the front end of the cabinet 1. Figure 5In the simplified diagram of the effect shown, the image of a "deer" displayed on the LCD screen is for illustration purposes only. In actual viewing, it is white with no image.

[0056] The third polarizer 232 is a special-shaped polarizer, which can be a square polarizer or a circular polarizer (the specific effect is shown in FIG. Figure 6 As shown) or other irregularly shaped polarizers are mainly used to meet the different experiences of users and enhance the display effect of exhibits.

[0057] Furthermore, a rotating mechanism (not shown in the figure) is also provided at the bottom of the booth 4. Specifically, the booth 4 is a disc, which can provide a larger placement space. At the same time, a frosted layer is provided on its surface so that the items placed on it are not easy to slide. The rotating mechanism includes a rotating disc and a motor. The rotating disc and the motor are driven by gears to drive the booth to rotate slowly and evenly, thereby providing users with displays at various angles on the spot.

[0058] At the same time, the present invention adopts the display method of the liquid crystal display cabinet with the separated polarizer, such as Figure 7 As shown, the specific steps are as follows:

[0059] S1: emitting a light source having two polarization directions through the backlight source 3;

[0060] S2: The light source obtains two groups of unidirectional polarized lights through the first group of polarizers 22;

[0061] S3: The main control board applies a deflection voltage to the liquid crystal glass 21 containing the image information;

[0062] After one group of the unidirectional polarized lights passes through the liquid crystal glass 21 to which the polarization voltage is applied, a single polarized light containing an image is obtained;

[0063] S4: The single polarized light containing the image passes through the third polarizer 232 to obtain an image in which the exhibit on the booth 4 is superimposed with the image information.

[0064] Furthermore, during the process of superimposing the exhibit and the image information, the exhibit rotates at a constant speed, so that the user can view the details of the entire exhibit without moving, and the user experience is further improved.
