Display structure having a laser light wavelength conversion layer

Abstract

A display structure having a laser light wavelength conversion layer includes a display in addition to the laser light wavelength conversion layer. The display has a backlight module and a display panel provided on the light output side of the backlight module. The display panel has a color filter and a light-permeable protective layer formed on the light output side of the color filter. The color filter has a plurality of color sub-pixels. The laser light wavelength conversion layer is formed between the color sub-pixels or on or in the light-permeable protective layer. The display, therefore, can function as a fabric-based projection screen by allowing a laser pointer to generate a visible light point on the images displayed by the display during a presentation.

DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to FIG. 1 to FIG. 3, the present invention provides a display structure 100 having a laser light wavelength conversion layer. The display structure 100 includes a display 10 and a laser light wavelength conversion layer 20.

(10) Referring to FIG. 4 in conjunction with FIG. 1 to FIG. 3, the display 10 in the present invention is provided with the laser light wavelength conversion layer 20 so that when the display structure 100 is used to display presentation material, the presenter may use a laser pointer 200 to guide the audience's attention to any position of the displayed presentation material directly with the laser light of the laser pointer 200.

(11) When the laser light strikes the laser light wavelength conversion layer 20, the laser light wavelength conversion layer 20 is excited by the laser light and generates a light point 201, with which the presenter can highlight wherever in the presentation material that he or she wishes to emphasize.

(12) For example, the display 10 is a liquid crystal display (LCD) 10 that serves as a computer screen or TV screen. The display 10, however, is not limited to a LCD and may instead be an organic light-emitting diode (OLED) display, a plasma display, or the like. The display 10 has a backlight module 210 and a display panel 220.

(13) The backlight module 210 functions mainly as the light source of the display 10 while the display 10 is in operation.

(14) The display panel 220 is provided on the light output side of the backlight module 210, and the display panel 220 has a color filter 221 and a light-permeable protective layer 222.

(15) The color filter 221 has a plurality of color sub-pixels 2211. The color sub-pixels 2211 may include red (R), green (G), and blue (B) color sub-pixels for example. When the light output from the backlight module 210 strikes the R, G, and B color sub-pixels 2211, the three primary colors R, G, and B are generated, and the different light colors are mixed to form a colorful screen image.

(16) The light-permeable protective layer 222 is formed on the light output side of the color filter 221 and serves mainly as a protective layer of the display panel 220. The light-permeable protective layer 222 may be a glass substrate.

(17) The laser light wavelength conversion layer 20 may be formed between the color sub-pixels 2211 at a position that will not block any of the color sub-pixels 2211. Alternatively, the laser light wavelength conversion layer 20 may be formed on or in the light-permeable protective layer 222.

(18) More specifically, referring to FIG. 5, FIG. 6, FIG. 7A, and FIG. 7B, the laser light wavelength conversion layer 20 may be formed on the inner side 2221 of the light-permeable protective layer 222, or the laser light wavelength conversion layer 20 may be formed on the outer side 2222 of the light-permeable protective layer 222. Moreover, the laser light wavelength conversion layer 20 may be formed as an inner sandwiched layer 2223 of the light-permeable protective layer 222.

(19) The above description is only the preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Although the invention has been disclosed as above in the preferred embodiments, they are not intended to limit the invention. A person skilled in the relevant art will recognize that equivalent embodiment modified and varied as equivalent changes disclosed above can be used without parting from the scope of the technical solution of the present invention. All the simple modification, equivalent changes and modifications of the above embodiments according to the material contents of the invention shall be within the scope of the technical solution of the present invention.
