Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a stage information display system based on a polarizer. Background Technology

[0002] In scenarios involving prolonged verbal output, such as stage performances and speeches, performers need timely access to cues to ensure a smooth performance. Traditionally, this involves carrying paper teleprompters or wearing in-ear monitors. However, paper teleprompters require manual page turning, disrupting the performance's flow, while in-ear monitor cues, being primarily audio prompts, can interfere with the performers' emotional engagement. Alternatively, wearing glasses to access on-screen cues is also common. While this allows performers to quickly grasp the content and ensures a smooth performance, the matching limitation between the glasses' transmission axis and the screen's pixel polarization direction means that only a portion of the screen's pixels are recognized and displayed, rendering the remaining pixels ineffective for the wearer, resulting in low overall screen utilization. Utility Model Content

[0003] In view of this, the main objective of this utility model is to provide a stage information display system based on a polarizing film, which displays different pixels through a display unit, and obtains the images corresponding to single-pixel and double-pixel points of the display unit respectively with the help of first polarizing glasses and second polarizing glasses, thereby enabling different prompt information to be obtained from the display unit at the same time, realizing multiple uses on one screen, and effectively improving the utilization rate of the display unit.

[0036] like Figure 1 As shown, this application embodiment provides a stage information display system based on a polarizer, including:

[0037] Display unit 100 is used to display different pixels;

[0038] The first polarized glasses 200 are disposed on the light-emitting side of the display unit 100 and are used to observe the image displayed at the corresponding pixel. The first polarized glasses 200 are provided with a first polarizer 210.

[0039] The second polarized glasses 300 are disposed on the light-emitting side of the display unit 100 and are used to observe the image displayed at the corresponding pixel. The second polarized glasses 300 are provided with a second polarizer 310, which is perpendicular to the transmission axis direction of the first polarizer 210.

[0040] In this embodiment, in order to improve the utilization rate of the display unit 100, the first polarized glasses 200 and the second polarized glasses 300 are used in conjunction with the display unit 100 to enable the users of the first polarized glasses 200 and the second polarized glasses 300 to see the images displayed by different pixels of the display unit 100 at the same time, thereby achieving multiple uses on one screen and effectively improving the utilization rate of the display unit 100.

[0041] Specifically, the transmission axes of the first polarizer 210 and the second polarizer 310 are perpendicular, enabling the images displayed by single pixels and dual pixels of the display unit 100 to be simultaneously observed when wearing the first polarized glasses 200 and the second polarized glasses 300. For example, a single pixel on the display unit 100 outputs vertically polarized light, while a dual pixel outputs horizontally polarized light. The first polarizer 210 is a vertical polarizer, and the second polarizer 310 is a horizontal polarizer. That is, the first polarizer 210 only transmits vertically polarized light, allowing the wearer to see the image displayed by the single pixel, while the second polarizer 310 only transmits horizontally polarized light, allowing the wearer to see the image displayed by the dual pixels. In other words, the display unit 100 can be fully utilized at the same time to transmit richer information to different wearers through different pixel areas, meeting the practical need to provide differentiated prompts to multiple people simultaneously.

[0042] In some embodiments, the display unit 100 includes:

[0043] Backplane module 110 is used to generate the initial light;

[0044] The third polarizer 120 is disposed on the light-emitting side of the back panel module 110 and is used to convert the initial light into polarized light.

[0045] The liquid crystal panel 130 is disposed downstream of the optical path of the third polarizer 120 and is used to deflect and modulate polarized light according to the deflection angle to obtain horizontally polarized light and / or vertically polarized light.

[0046] In this embodiment, as Figure 2 and Figure 3 As shown, the display unit 100 includes a backplane module 110, a third polarizer 120, and a liquid crystal panel 130 stacked together. The backplane module 110 generates initial light, i.e., uniform white backlight, as the basic light source for the display unit 100. The white backlight is unpolarized white light, containing light waves in all vibration directions. The third polarizer 120 is specifically disposed on the light-emitting side of the backplane module 110, filtering the initial light emitted by the backplane module 110 into linearly polarized light vibrating in a specific direction, that is, converting unpolarized light into linearly polarized light, including vertical or horizontal directions. Simultaneously, the liquid crystal panel 130 is disposed on the side of the third polarizer 120 opposite to the backplane module 110. Applying a voltage changes the arrangement of liquid crystal molecules, thereby rotating the polarization direction of the linearly polarized light passing through the liquid crystal panel 130.

[0047] Specifically, in one scenario, horizontally polarized light passing through the third polarizer 120 enters a single-pixel liquid crystal unit, where the liquid crystal molecules rotate 90 degrees, outputting vertically polarized light. Similarly, horizontally polarized light passing through the third polarizer 120 enters a dual-pixel liquid crystal unit, where the liquid crystal molecules maintain their original orientation, outputting horizontally polarized light. Subsequently, the vertically polarized light from the single-pixel unit and the horizontally polarized light from the dual-pixel unit reach the first polarized glasses 200 and the second polarized glasses 300. If the first polarizer 210 is a vertical polarizer and the second polarizer 310 is a horizontal polarizer, the vertically polarized light can pass through the vertically polarized first polarizer 210, maintaining its vertical polarization, allowing the wearer of the first polarized glasses 200 to see the image corresponding to the single pixel. Conversely, the horizontally polarized light can pass through the horizontally polarized second polarizer 310, maintaining its horizontal polarization, allowing the wearer of the second polarized glasses 300 to see the image corresponding to the dual pixel. Therefore, in practical applications, users can see both pattern A, which corresponds to a single pixel of display unit 100, and pattern B, which corresponds to a double pixel of display unit 100, at the same time. This not only improves the utilization rate of display unit 100 but also meets the visual needs of more users.

[0048] In some embodiments, the backplane module 110, the third polarizer 120, and the liquid crystal panel 130 are bonded together by optically transparent adhesive.

[0049] In this embodiment, the third polarizer 120 is directly laminated onto the light-emitting surface of the back panel module 110 using optically transparent adhesive. The optically transparent adhesive in this embodiment needs to meet the requirements of high light transmittance and no air bubbles. By filling the air with the optically transparent adhesive, scattering loss can be effectively avoided. Simultaneously, the high light transmittance ensures the brightness of the display unit 100 as a white background. Furthermore, the third polarizer 120 and the liquid crystal panel 130 are also bonded together using optically transparent adhesive, specifically through gapless lamination, thereby preventing light reflection between the air and the interface and reducing reflection loss.

[0050] In some embodiments, the first polarized glasses 200 includes:

[0051] First frame body;

[0052] The first lens substrate 220 is disposed on the first frame body, and the first polarizer 210 is disposed on the front side of the first lens substrate 220.

[0053] In this embodiment, the first lens substrate 220 is disposed on the first frame body, and the first polarizer 210 is disposed on the front side of the first lens substrate 220, that is, on the side closer to the display unit 100. It should be noted that, in this embodiment, by disposing the first polarizer 210 on the front side of the first lens substrate 220, compared to disposing it on the rear side of the first lens substrate 220, the occurrence of ambient stray light interfering with the polarization state of the light emitted from the display unit 100 can be effectively reduced. This ensures that the light emitted from the display unit 100 is filtered out in the first instance, reducing polarization state mixing caused by air scattering or internal reflection of the lens.

[0054] In some embodiments, the first lens substrate 220 and the first polarizer 210 are bonded together by optically transparent adhesive.

[0055] In this embodiment, optical transparent adhesive is used to tightly bond the first lens substrate 220 and the first polarizer 210 together, thereby achieving integrated bonding of the first lens substrate 220 and the first polarizer 210, effectively solving the problem of air gaps between interfaces and maximizing transmittance.

[0056] In some embodiments, the second polarized glasses 300 include:

[0057] Second frame body;

[0058] The second lens substrate 320 is disposed on the second frame body, and the second polarizer 310 is disposed on the front side of the second lens substrate 320.

[0059] In this embodiment, the second lens substrate 320 is disposed on the second frame body, and the second polarizer 310 is disposed on the front side of the second lens substrate 320, that is, on the side closer to the display unit 100. The placement of the second polarizer 310 on the front side of the second lens substrate 320 effectively reduces the occurrence of ambient stray light interfering with the polarization state of the light emitted from the display unit 100, ensuring that the emitted light from the display unit 100 is filtered out immediately, reducing polarization state mixing caused by air scattering or internal reflections within the lens.

[0060] In some embodiments, the second lens substrate 320 and the second polarizer 310 are bonded together by optically transparent adhesive.

[0061] In this embodiment, optically transparent adhesive is used to tightly bond the second lens substrate 320 and the second polarizer 310 together, thereby achieving integrated bonding of the second lens substrate 320 and the second polarizer 310, effectively solving the problem of air gaps between interfaces and maximizing transmittance.

[0062] In some embodiments, the first polarizer 210 is a vertical polarizer or a horizontal polarizer.

[0063] In this embodiment, the first polarizer 210 can be either a vertical polarizer or a horizontal polarizer. Since the transmission axes of the first polarizer 210 and the second polarizer 310 are perpendicular, when the first polarizer 210 is a vertical polarizer, the second polarizer 310 is correspondingly set as a horizontal polarizer; conversely, when the first polarizer 210 is a horizontal polarizer, the second polarizer 310 is correspondingly set as a vertical polarizer. In practical applications, after the display unit 100 outputs polarized light pixel by pixel, the first polarized glasses 200 and the second polarized glasses 300 split the light according to the polarization direction.

[0064] Taking a display unit 100 where a single pixel emits vertically polarized light and a dual pixel emits horizontally polarized light, with the first polarizer 210 being a vertical polarizer and the second polarizer 310 being a horizontal polarizer, as an example, the image A corresponding to a single pixel can pass through the first polarizer 210, allowing the wearer to see image A. However, the pattern B corresponding to a dual pixel is blocked by the first polarizer 210, preventing horizontally polarized light from entering the corresponding eye, thus making pattern B invisible. Similarly, the image B corresponding to a dual pixel can pass through the second polarizer 310, allowing the wearer to see pattern B, while the pattern A corresponding to a single pixel is blocked by the second polarizer 310, preventing vertically polarized light from entering the corresponding eye, thus making pattern A invisible. Therefore, by cooperating with the display unit 100, the first polarized glasses 200 and the second polarized glasses 300 allow users of both glasses to see images displayed at different pixels of the display unit 100 simultaneously, improving the utilization rate of the display unit 100. That is, the same display unit 100 can be used to provide different users with separate and isolated visual content at the same time, effectively improving the reuse effect of the display unit 100.

[0065] In some embodiments, it also includes:

[0066] The third polarized glasses 400 are disposed on the light-emitting side of the display unit 100, and a fourth polarizer 410 and a fifth polarizer 420 are disposed in front of the lenses on both sides of the third polarized glasses 400, and the transmission axes of the fourth polarizer 410 and the fifth polarizer 420 are perpendicular to each other.

[0067] like Figure 4As shown, in this embodiment, a third polarized glasses 400 is also provided, and a fourth polarizer 410 and a fifth polarizer 420 with perpendicular transmission axes are correspondingly provided in front of the lenses 430 on both sides of the third polarized glasses 400. By adding the fourth polarizer 410 and the fifth polarizer 420 to the lenses 430 on both sides of the third polarized glasses 400, and the transmission axes of the fourth polarizer 410 and the fifth polarizer 420 being perpendicular, and in conjunction with the single-pixel and dual-pixel imaging of the display unit 100, a 3D display effect can be achieved, providing users with richer visual content. For example, a single pixel on the display unit 100 outputs vertically polarized light, and a dual pixel outputs horizontally polarized light. In front of the lenses on both sides of the corresponding third polarized glasses 400, a fourth polarizer 410 on one side is a vertical polarizer, and a fifth polarizer 420 on the other side is a horizontal polarizer. That is, the fourth polarizer 410 only transmits vertically polarized light, so that the corresponding eye, such as the left eye, can see the image displayed corresponding to the single pixel, and the fifth polarizer 420 only transmits horizontally polarized light, so that the corresponding eye, such as the right eye, can see the image displayed corresponding to the dual pixel. This achieves the purpose of allowing the left and right eyes to receive different images, thus realizing a 3D visual effect.

[0068] In some embodiments, there are multiple third polarized glasses 400.

[0069] In this embodiment, there are multiple third polarized glasses 400, which can be freely selected according to actual needs to meet the usage needs of more performance-related personnel.
