Description

Display with stereoscopic image display function and manufacturing method thereof

The invention relates to a display with a stereoscopic image display function and a manufacturing method thereof, in particular to a display for making a three-dimensional microstructure on a lower surface of a polarizer by means of printing, coating or exposure development, and a manufacturing method thereof.

With the evolution of optoelectronics and semiconductor technology, the development of flat panel displays has been promoted. Among many flat panel displays, liquid crystal displays (LCDs) have superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. It immediately became the mainstream product of the market. It is well known that a liquid crystal display includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not have self-luminous characteristics, the backlight module must be disposed under the liquid crystal display panel to provide liquid crystal. The surface light source required for the display panel. In this way, the liquid crystal display can display the image image for the user to watch.

The design of the backlight module that is conventionally provided to the surface light source required for the liquid crystal display panel generally provides a white light, and then passes through a color filter at each pixel position in the liquid crystal display panel to display each color filter. The color that the pixel wants to present. Therefore, according to the above, it is necessary to set a color filter having three colors of red (R), green (G), and blue (B) at each pixel position, and this method not only consumes production cost but also passes color. The light transmittance of each pixel after the filter is also relatively low.

Therefore, in the liquid crystal display designed recently, a backlight using a light-emitting diode (LED) as a backlight instead of white light has been proposed. That is, the color will be The color filter is mixed on the spatial axis, and the red (R), green (G) and blue (B) three color images are quickly switched on the time axis to generate the time range of the human eye. The effect of color mixing.

For example, if you display 60 images per second of a motion picture as an example, you can quickly switch between red (R), green (G), and blue (B) colors on the time axis. Red (R), green (G) ) and blue (B) three color image update frequency needs at least 180 images per second, that is, the picture update period is 1/180 seconds, and this method is also called the field color sequence method, so there is no need to set the color filter The light sheet is in the liquid crystal display panel, thereby improving the light transmittance displayed by each pixel.

FIG. 6 is a timing diagram of a light source module of a display having a stereoscopic image display function using three colors of red, green, and blue light sources.

Referring to FIG. 1 to FIG. 5, the present invention provides a stereoscopic image display. The method for manufacturing the functional display Z can include at least the following steps: First, as shown in FIG. 1 and FIG. 2, a polarizer 4 having an upper surface and a lower surface (ie, a non-adhesive lower surface) is provided. 40) (step S100).

Next, as shown in FIG. 1 and FIG. 2, a three-dimensional microstructure 3 (that is, a 3D pattern or a 3D film) is formed on the lower surface of the polarizer 4 (step S102). For example, the stereo microstructure 3 can be formed on the non-adhesive lower surface 40 of the polarizer 4 via printing, coating or exposure development (semiconductor process), etc., so that the stereo microstructure 3 naturally forms a corresponding non- The non-adhesive upper surface 30 of the viscous lower surface 40. In other words, the three-dimensional microstructure 3 is non-adhesively disposed on the non-adhesive lower surface 40 of the polarizer 4 in a non-adhesive manner.

Finally, as shown in FIG. 1 and FIG. 3, the three-dimensional microstructure 3 is attached to the display panel 2 (step S104). For example, the three-dimensional microstructures 3 may be attached to the display panel 2 via an adhesive (not shown) or an adhesive sheet (not shown).

Therefore, with reference to FIG. 1 and FIG. 5, the present invention can provide a display Z having a stereoscopic image display function, including a light source module 1, a display panel 2, and the method of the steps S100 to S104. A three-dimensional microstructure 3 and a polarizer 4 (ie, an upper polarizer).

First, the light source module 1 can be used to provide a light source L (ie, a surface light source), the display panel 2 is disposed above the light source module 1, the stereoscopic microstructure 3 is disposed on the display panel 2, and the polarizer 4 is disposed on the stereo microstructure. 3 on. Furthermore, the display panel 2, the stereoscopic microstructure 3 and the polarizer 4 are sequentially stacked from bottom to top, so that the light source L generated by the light source module 1 can sequentially pass through the display panel 2, the stereo microstructure 3 and the polarized light. Sheet 4 to project a stereoscopic image M.

For example, according to different design requirements, the display panel 2 can be a TFT (Thin-film Transistor) liquid crystal panel or a FSC (Field Sequential Color) liquid crystal panel, and provided by the light source module 1 The light source L can be used as a backlight source of the display panel 2. As shown in FIG. 5, when the display panel 2 can be a TFT liquid crystal panel, the display panel 2 can include a lower polarizer 21 and a stack. A liquid crystal panel 22 stacked on the lower polarizer 21, a color filter 23 stacked on the liquid crystal panel 22, and a glass substrate 24 stacked on the color filter 23. Therefore, the three-dimensional microstructures 3 can be disposed on the glass substrate 24 of the display panel 2 via attachment.

For another example, since the stereoscopic microstructure 3 can be formed on the lower surface of the polarizer 4 via printing, plating, or exposure development (semiconductor process), the polarizer 4 can have a non-adhesive lower surface 40. The three-dimensional microstructure 3 may have a non-adhesive upper surface 30 corresponding to the non-adhesive lower surface 40, and the non-adhesive upper surface 30 of the three-dimensional microstructure 3 and the non-adhesive lower surface 40 of the polarizer 4 are in contact with each other to The three-dimensional microstructures 3 are non-adhesively disposed on the non-adhesive lower surface 40 of the polarizer 4 in a non-adhesive manner. Furthermore, since the stereoscopic microstructure 3 of the present invention can be disposed on the non-adhesive lower surface 40 of the polarizer 4 without attaching, the present invention can not only effectively reduce the overall weight, but also not because The adhesive is used to reduce the overall transmittance. Of course, there is no problem of any alignment between the three-dimensional microstructure 3 and the polarizer 4. Therefore, the display Z having the stereoscopic image display function of the invention not only has a light weight and a high transmittance, but also the alignment between the stereo microstructure 3 and the polarizer 4 can be very accurate, thereby effectively improving the yield of the product. And reduce production costs.

It is worth mentioning that the light source L generated by the light source module 1 may be a backlight source including a red light source, a green light source and a blue light source, or the light source L generated by the light source module 1 may also be a red light source. Backlight source for green light source, blue light source and white light source. For example, as shown in FIG. 6 , the display Z belongs to the Field Sequential Color LCD (for example, when the display panel 2 is an FSC liquid crystal panel), and the light source module 1 can be based on one screen. the length of time T _F, at synchronization (sYNC), in order to time-division multiplexing manner are sequentially outputted to the display panel 2, for example, a first cycle may output a time length of the red light _R T R, 2 cycles may output a time length of the green light _G T G, and the third cycle may output a time length of the blue light _B T B, at this time after mixing is obtained through the color pixels (pixel) of a synthesis. Therefore, when the present invention adopts three primary colors (red, green, and blue) as the light source of the light source module 1, the display Z having the stereoscopic image display function of the present invention can be used without using a color filter. The same color display function can be achieved, while increasing color saturation and reducing manufacturing costs.
