Abstract
Description
Technical Field
[0001] The invention relates to a display structure with a laser wavelength conversion layer, in particular to a display structure with a laser wavelength conversion layer for a computer display or a computer screen used for conference presentations. Background Art
[0002] A projector is a display device that uses an optical system to magnify images and project them onto a screen. Some projectors are used to play movies for entertainment, but a considerable proportion of them are used in multi-person meetings to project the content to be discussed onto a screen, and use a laser projection pen to guide the laser point, so that all participants can watch simultaneously and communicate effectively.
[0003] However, when using a projector, a sufficient distance is usually required, and a screen is also required to complete the image. Therefore, in addition to the cost of installation, there are still many limitations on the space. Compared with the current development of televisions or computer screens, large-size screens can be produced, so using screens for multi-person conference communication has gradually replaced projectors and become a trend.
[0004] However, the biggest problem with holding multi-person meetings on TV or computer screens is that the light spot of the laser projector pen cannot be displayed on the TV or computer screen, so the only way to guide the meeting is to use a mouse cursor that is not very visible. It is impossible to use the laser point of the laser projector pen to more effectively guide the meeting to proceed smoothly when the projector is used in conjunction with the screen. Summary of the invention
[0005] The present invention is a display structure with a laser wavelength conversion layer, which is mainly used to solve the problem that when a computer display or a computer screen is used for conference presentation, it is impossible to use a laser projection pen to directly guide the current presentation content.
[0006] The present invention provides a display structure with a laser wavelength conversion layer, which includes: a display having: a backlight module; a display panel, which is arranged on the light-emitting side of the backlight module, and the display panel has: a color filter, which has a plurality of color units; and a light-transmitting protective layer, which is formed on the light-emitting side of the color filter; and a laser wavelength conversion layer, which is formed between the plurality of color units or on the light-transmitting protective layer.
[0007] By implementing the present invention, at least the following improved effects can be achieved:
[0008] 1. It can make the display surface of the computer display or computer screen show the light spot of the laser projection pen.
[0009] Second, the computer display or computer screen can also function as a projection display screen.
[0010] In order to enable anyone skilled in the relevant art to understand the technical content of the present invention and implement it accordingly, and based on the contents disclosed in this specification, the scope of the patent application and the drawings, any person skilled in the relevant art can easily understand the relevant purposes and advantages of the present invention, so the detailed features and advantages of the present invention will be described in detail in the implementation mode.

[0028] like Figures 1 to 3 As shown, the present invention is a display structure 100 with a laser wavelength conversion layer, which includes: a display 10; and a laser wavelength conversion layer 20.
[0029] like Figures 1 to 4 As shown, the present invention sets a laser wavelength conversion layer 20 on the display 10, so that when the display structure 100 is used as a device for displaying presentation content, the presenter can use a laser pen 200 to directly point the laser to the position where the audience or participants want to pay attention to the presentation content.
[0030] When the laser is transmitted to the laser wavelength conversion layer 20 , the laser wavelength conversion layer 20 will be excited by the laser to generate a light spot 201 . The light spot can be used to achieve the purpose of the presenter indicating the location of the presentation content to be prompted.
[0031] The display 10 is, for example, a liquid crystal display 10 of a computer screen or a television screen, but is not limited to a liquid crystal display, and may also be an OLED display, a plasma display, etc. The display 10 includes: a backlight module 210; and a display panel 220.
[0032] The backlight module 210 mainly provides light source for the display 10 when displaying.
[0033] The display panel 220 is disposed on the light-emitting side of the backlight module 210 , and the display panel 220 includes a color filter 221 and a light-transmitting protection layer 222 .
[0034] The color filter 221 has a plurality of sub-pixels 2211. The sub-pixels 2211 may include, for example, R, G, and B sub-pixels. When the light emitted by the backlight module 210 is irradiated on the sub-pixels 2211, the three primary colors of R, G, and B are generated, and then mixed to form a color screen display.
[0035] The light-transmitting protective layer 222 is formed on the light-emitting side of the color filter 221 , and mainly serves as a protective layer for the display panel 220 . The light-transmitting protective layer 222 may be a glass substrate.
[0036] The laser wavelength conversion layer 20 is formed between the plurality of color units 2211 without shielding any color unit 2211 ; or the laser wavelength conversion layer 20 is formed on the light-transmitting protection layer 222 .
[0037] like Figure 5 , Figure 6 , Fig. 7A and Figure 7BSpecifically, the laser wavelength conversion layer 20 can be formed on the inner side 2221 of the light-transmitting protective layer 222, or the laser wavelength conversion layer 20 can be formed on the outer side 2222 of the light-transmitting protective layer 222. In addition, the laser wavelength conversion layer 20 can also be formed on the inner interlayer 2223 of the light-transmitting protective layer 222.
[0038] However, the above embodiments are used to illustrate the features of the present invention, and their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly, rather than to limit the patent scope of the present invention. Therefore, any other equivalent modifications or modifications that do not deviate from the spirit disclosed by the present invention should still be included in the scope of the patent application described below.
