Replaceable display system

The present invention relates to a replaceable display system, and more particularly to a replaceable display system for displaying a pattern by an image film.

In general, the display medium (or electronic ink) of electrophoretic display technology is mainly composed of an electrophoresis liquid and white charged particles doped into the electrophoresis liquid. The display medium is disposed between the upper and lower protective films to form a display medium layer, and the white charged particles are driven to move by applying a voltage, so that each pixel displays black, white or gray scale respectively.

In the prior art, the electrophoretic display mostly uses the reflection of the external light source to achieve the purpose of display, and the white charged particles doped in the electrophoresis liquid by the voltage driving can cause the respective pixels to display the desired gray scale. Furthermore, in order to expand the application of the electrophoretic display, a color filter film may be added to the display medium layer, and the color filter film may be fixed to the display medium layer through the adhesive layer.

In the following description, the display back panel 110 having the electrophoretic display module will be described as an example, and the configuration and use state of the replaceable display system 100 will be described in detail.

Figure 3 is a cross-sectional view of the interchangeable display system 100 of Figure 1 taken along section line 3-3'. Referring also to FIGS. 2 and 3, the array substrate 140 has A plurality of pixel units 142. The pixel unit 142 includes a thin film transistor 144 and a pixel electrode 146. The front panel 150 is located on the array substrate 140 and includes a transparent substrate 151, a display medium layer 154, and a common electrode 158. The secondary display area 153 is displayed as a bright or dark surface by the display medium layer 154, respectively. More specifically, the display medium layer 154 is located between the array substrate 140 and the transparent substrate 151 and includes a plurality of microcapsules 156. Each microcapsule 156 has a plurality of brightly colored electrophoretic particles 155 (e.g., white particles) and a plurality of dark electrophoretic particles 157 (e.g., black particles). Further, the common electrode 158 is located on the transparent substrate 151 and opposed to the pixel electrode 146, and the microcapsule 156 is located between the common electrode 158 and the pixel electrode 146.

In use, the electric field between the common electrode 158 and each of the pixel electrodes 146 can be changed by the controller 120 such that the bright electrophoretic particles 155 or the dark electrophoretic particles 157 are located above (ie, the side close to the image film 130). When the bright color electrophoretic particles 155 are above and the dark electrophoretic particles 157 are below (ie, the side away from the image film 130), the secondary display region 153 can reflect the ambient incident light and appear as a bright surface (eg, white). Conversely, when the bright color electrophoretic particles 155 are below and the dark electrophoretic particles 157 are above, the secondary display region 153 does not reflect the incident light of the environment and is displayed as a dark surface (for example, black). Further, when the partial bright color electrophoretic particles 155 and the partial dark electrophoretic particles 157 are located at a ratio above, the sub display region 153 may be displayed as a gray scale.

That is, each display area 153 may cover a portion of the display medium layer 154 and a portion of the pixel unit 142.

The controller 120 can display all of the secondary display areas 153 as a dark surface in sequence by the setting of the software. Thereafter, the sub-display area 153 below the circular light-transmissive pattern portion 132 is displayed as a bright surface. Next, the sub-display area 153 under the triangular light-transmissive pattern portion 132 is displayed as a bright surface, while the sub-display area 153 under the circular light-transmissive pattern portion 132 is displayed as a dark surface. Thereafter, the sub-display area 153 under the rectangular light-transmissive pattern portion 132 is displayed as a bright surface, and the sub-display area 153 under the triangular light-transmitting pattern portion 132 is displayed as a dark surface. Next, the circular, triangular, and sub-display regions 153 below the rectangular light-transmissive pattern portion 132 are simultaneously displayed as bright surfaces. Thereafter, it returns to the state in which all of the sub-display areas 153 are simultaneously displayed as dark surfaces. In this way, when the sub-display area 153 covered by the image film 130 can be dynamically changed between the bright side and the dark side, the light-transmissive pattern part The pattern of 132 is also alternated between light and dark, and the interchangeable display system 100 can be applied to an advertising poster to create a special effect.

In the present embodiment, the shape of the secondary display area 153 is a rectangle, but is not limited thereto. In other embodiments, the shape of the secondary display area 153 may also be a rectangle, a square, a regular hexagon, a polygon, a circle, or any combination of the above. The secondary display area 153 serves only as a back reflection face of the image film 130, and the size and number of the secondary display areas 153 can be designed in accordance with the size of the light-transmitting pattern portion 132 of the image film 130.

Fig. 6 is a cross-sectional view showing the light-transmitting pattern portion 132 of Fig. 4 when it is displayed. Referring to FIG. 2 and FIG. 6 simultaneously, when the display backplane 110 is a bi-stable display module, such as an electrophoretic display module or a cholesterol liquid crystal display module, and the secondary display area 153 is displayed as a bright surface, the ambient light source is The incident light L1 can pass through the light transmissive pattern portion 132 of the image film 130 and be reflected by the sub-display region 153 which is displayed as a bright surface. The reflected incident light L1 can pass through the image film 130 and enter the human eye, so that the pattern of the light transmitting pattern portion 132 is displayed.

Since the image film 130 is detachably located on the display area 152, and the light transmissive pattern portion 132 of the image film 130 is displayed by the sub-display area 153 displayed as a bright surface, the replaceable display system 100 can be placed on the display by replacement. The image film 130 on the area 152 displays different patterns. That is, the display back panel 110 does not directly display an image, but only serves as a background reflection surface of the light transmission pattern portion 132, and allows light to be displayed through the light transmission pattern portion 132. In this way, the number of the sub-display areas 153 of the display backplane 110 and the number of the pixel units 142 of the array substrate 140 can be saved, so that the display backplane 110 has a lower resolution to save manufacturing costs.

When the image film 130 having the different light transmitting pattern portions 132 is replaced, only The secondary display area 153 located below the light transmissive pattern portion 132 is displayed as a bright surface by the controller 120, so that the interchangeable display system 100 can display different patterns. Compared with the conventional paper advertising poster, the interchangeable display system 100 can display different patterns by different image films 130, and the image film 130 can be reused without being easily disassembled, thereby saving paper waste and protect environment.
