Description

Technical Field

[0001] The present invention relates to the field of electronic paper segmented display, in particular to an electronic paper backboard and an electronic paper display screen. Background Art

[0002] The electronic paper ink screen display has the characteristics of ultra-low power consumption, low-frequency display, and power saving. It has a wide range of applications in price tags, educational tablets, and bus stops. At present, the electronic paper display forms on the market include dot matrix screens (that is, the voltage changes of the scan lines and data lines are used to control the opening or closing of the unit pixel TFT device to achieve dot matrix screen display); the segment code screen is to connect each segment unit directly to the FPC through a conductive line to achieve simple screen and digital display; the color-changing electronic paper module screen is a new branch of the segment code screen application, which can display the same color on the entire surface and color screens, and has fast refresh and rich color display characteristics. It has important application potential in color-changing tiles, digital electronic product shells, automobiles, clothing, etc. At present, the color-changing electronic paper display is highly valued by consumer end customers because of its simple design, short production cycle, rich color display, and can be applied to flexible / thin scenes.

[0003] In current color-changing electronic paper, each independent graphic block needs to be connected to the driving port of the driver IC (driver chip) with a separate electrode line to drive the graphic block display. The more graphic blocks are displayed, the more driver IC driving ports are used. However, the number of driver IC output ports is limited. For example, the driver IC has 64 driving ports. According to conventional design, the maximum number of design segments of a driver IC is only 64, which results in only being able to display a certain number of graphic blocks, and the display effect is poor.

[0004] Therefore, there is an urgent need to explore new design methods so that more than 64 segments of graphic blocks can be designed using one IC, making the display effect richer and thus improving the competitiveness of the product. Summary of the invention

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In current color-changing electronic paper, each independent graphic block needs to be connected to the driving port of the driver IC (driver chip) with a separate electrode line to drive the graphic block display. The more graphic blocks displayed, the more driver IC driving ports will be used.

[0051] However, the number of driver IC output ports is limited. For example, if a driver IC has 64 driver ports, the maximum number of design segments using a driver IC is only 64 according to conventional design. This results in only being able to display a certain number of graphic blocks, resulting in poor display effects. Figure 1 , Figure 1 Schematic diagram of an existing conventional electronic paper back panel provided for an embodiment of the present invention. The background color area 1 in the conventional electronic paper back panel is the background of the electronic paper display content, providing necessary visual support for display content such as images. Figure 1 As shown, each graphic block 2 in a conventional electronic paper back panel requires an electrode line to be connected to a driver IC drive port. For example, eight triangular graphic blocks in a sun graphic require eight electrode lines to be connected to eight drive ports respectively, which results in a low utilization rate of the driver IC drive port and can only realize the display of a specific number of graphic blocks.

[0065] Furthermore, if Figure 2 As shown, a plurality of the series-connected pattern blocks 21 form a plurality of series circuits on the conductive metal layer through electrode lines 3 based on preset characteristic requirements.

[0066] Specifically, Figure 2As shown, the present invention connects eight triangular graphic blocks around a sun graphic in series with electrode wires to form a series circuit, and finally electrically connects the series circuit to a driving port through an electrode wire, thereby reducing the original eight electrode wires to one electrode wire, thereby achieving the purpose of one driving port driving multiple graphic blocks while maintaining the original display effect.

[0067] In the present invention, several of the series-connected graphic blocks 21 form several series circuits on the conductive metal layer based on preset characteristic requirements through electrode lines 3, and the input end of each series circuit is electrically connected to different drive ports respectively.

[0070] Furthermore, if Figure 3 As shown, a plurality of the series-connected pattern blocks 21 are formed into a plurality of series circuits on the pattern electrode layer 5 through the pattern conductive material 4 based on preset characteristic requirements.

[0071] Specifically, Figure 3 As shown, the present invention connects eight triangular graphic blocks around the sun graphic in series on the graphic electrode layer 5 with a graphic conductive material 4 to form a series circuit, and can drive all the series graphic blocks 21 on a series circuit through one driving port, thereby achieving the purpose of one driving port driving multiple graphic blocks, thereby enabling more graphic blocks to be displayed under a limited number of driving ports.

[0072] Furthermore, the present invention directly forms a plurality of series circuits on the graphic conductive material 4, which can avoid the need for more electrode lines 3 to form a series circuit on the metal conductive layer for a plurality of series graphic blocks 21 and a plurality of independent graphic blocks, thereby reducing the complexity of circuit design and circuit wiring.

[0073] In the present invention, several of the series-connected graphic blocks 21 are formed into several series circuits on the graphic electrode layer 5 through the graphic conductive material 4 based on preset characteristic requirements, and the input end of each series circuit is electrically connected to different driving ports respectively. All the series-connected graphic blocks 21 on a series circuit can be driven by one driving port, so that one driving port drives multiple graphic blocks, thereby realizing more graphic block display under a limited number of driving ports, saving the driving port resources of the driving module, enriching the picture display effect, and improving the competitiveness of the product.

[0074] In this embodiment, the pattern conductive material 4 may be, but is not limited to, a carbon conductive material and a silver conductive material.

[0075] Furthermore, the width of the patterned conductive material 4 is within a preset width range.

[0076] In this embodiment, the preset width range is 0.5 mm-5 mm. By designing the width of the graphic conductive material 4 to be within the preset width range, the design of the electronic paper backplane circuit can be simplified and meet actual application requirements.

[0077] In the present invention, it is necessary to determine the appropriate width of the graphic conductive material 4 according to specific application scenarios, design requirements, production processes and cost considerations, so that the electronic paper backplane meets actual application requirements.

[0078] Furthermore, an insulating layer 10 or a substrate 7 is provided between the graphic electrode layer 5 and the conductive metal layer;

[0079] Furthermore, a plurality of first through holes are formed on the insulating layer 10 or the substrate base material 7 to electrically connect a plurality of series-connected pattern blocks 21 and a plurality of independent pattern blocks with the conductive metal layer.

[0080] In the present invention, a plurality of first through holes are opened in the insulating layer 10 or the substrate base material 7 to realize electrical connection between a plurality of serially connected graphic blocks 21 and a plurality of independent graphic blocks and the conductive metal layer, and further enable a plurality of serially connected graphic blocks 21 to form a series circuit on the conductive metal layer, thereby achieving the purpose of one driving port driving a plurality of graphic blocks, and realizing the display of more graphic blocks under a limited number of driving ports.

[0081] The substrate base material 7 is made of flexible material; the flexible material includes PET, PI and FPC.

[0082] The substrate base material 7 described in the present invention is made of flexible material, which can make the electronic paper backboard light, thin, bendable and foldable, not easy to break and durable, greatly reducing the weight of the product and being able to adapt to various complex usage scenarios and shape requirements; among them, the PET material can ensure the clarity and brightness of the graphics displayed on the electronic paper backboard and reduce the production cost of the electronic paper backboard, the PI material makes the electronic paper backboard have the advantages of high temperature resistance and corrosion resistance, and the FPC material makes the electronic paper backboard highly flexible.

[0083] Please refer to the following Figures 4 to 6 .

[0084] Furthermore, if Figures 4 to 6 As shown, the conductive metal layer includes a plurality of sub-conductive metal layers;

[0085] The plurality of sub-conductive metal layers are isolated from each other by insulating material 9 to form a multi-layer stacked circuit structure;

[0086] A plurality of the series-connected pattern blocks 21 and a plurality of the independent pattern blocks are electrically connected to any of the sub-conductive metal layers respectively;

[0087] A plurality of the series pattern blocks 21 form a plurality of series circuits on any sub-conductive metal layer based on preset characteristic requirements;

[0088] Each series circuit and each independent graphic block are independent of each other;

[0089] The input end of each series circuit and each independent graphic block are electrically connected to different driving ports respectively.

[0090] In the present invention, several of the sub-conductive metal layers form a multi-layer stacked circuit structure, which can arrange more circuit elements and connecting lines within a limited electronic paper backboard area, thereby improving the circuit integration of the electronic paper backboard and achieving a more complex and richer display effect. In addition, the design of the layer stacked circuit structure can optimize the circuit layout, and can plan the circuit layout more flexibly, so that each series circuit and each independent graphic block are independent of each other, avoiding interference and conflict between circuits, helping to reduce noise and signal loss in the electronic paper backboard, improving the stability and reliability of the electronic paper backboard display, and helping to promote the expansion of the application scope of the electronic paper backboard.

[0091] Furthermore, the insulating material 9 is provided with a plurality of second through holes;

[0092] When a number of the series graphic blocks 21 form a closed series circuit on any sub-conductive metal layer based on preset characteristic requirements, a number of the series graphic blocks 21 and a number of independent graphic blocks are electrically connected to any sub-conductive metal layer through a number of first through holes and a number of second through holes, respectively, so that each series circuit and each independent graphic block are independent of each other.

[0093] like Figure 4 As shown, when the eight triangular graphic blocks of the sun graphic form a closed series circuit in a sub-metal conductive layer, the circular graphic blocks in the sun graphic are in a closed state. At this time, another sub-metal conductive layer is required to connect the circular graphic blocks to the driving port through electrode lines to achieve separate driving and display of the circular graphic blocks to avoid short-circuiting of the circuit lines.

[0094] like Figure 5 and Figure 6 As shown, when there is a closed series circuit, the present invention adopts at least two layers of sub-conductive metal layers to realize the series design of multiple series graphic blocks. Specifically, a plurality of series graphic blocks 21 and a plurality of independent graphic blocks 22 can be electrically connected to any sub-conductive metal layer through a plurality of first through holes and a plurality of second through holes. Thus, through the routing of multi-layer electrode lines, the conductive metal layer with the closed series circuit is crossed over the first conductive metal layer, so that each series circuit and each independent graphic block 22 are independent of each other. While reducing the driving port resources, it can avoid the occurrence of line short circuits, which affects the display effect of the electronic paper backplane, and contributes to clearer and more accurate image display.

[0095] In this embodiment, the electronic paper backplane proposed by the present invention can adopt a double-sided perforated printing process or a single-sided printing process to realize the circuit diagram design of the graphic electrode layer 5, wherein: Figure 5 This is a schematic diagram of the cross section of the electronic paper backplane using a double-sided perforated printing process. Figure 6 Schematic diagram of the cross section of an electronic paper back panel using a single-sided printing process; taking the PET substrate as an example, the double-sided perforated printing process means that the graphic electrode layer 5 and the conductive metal layer (including the first sub-conductive metal layer 61 and the second sub-conductive metal layer 62 and other sub-conductive metal layers in this embodiment) are respectively on both sides of the PET substrate; the single-sided printing process means that the graphic electrode layer 5 and the conductive metal layer (including the first sub-conductive metal layer 61 and the second sub-conductive metal layer 62 and other sub-conductive metal layers in this embodiment) are both on one side of the PET substrate; among them, the double-sided perforated printing process and the single-sided printing process belong to screen printing processes, and the electronic paper back panel designed by the single-sided printing process has a waterproof function.

[0096] Accordingly, in order to solve the above technical problems, the present invention further provides an electronic paper display screen, comprising an electronic paper back panel, a wiring module and an electronic paper display screen housing as described above;

[0097] The electronic paper back plate is installed inside the electronic paper display screen housing;

[0098] The wiring module is arranged at a preset interface position of the electronic paper display screen housing, and is used for being electrically connected to the driving module of the electronic paper backboard.

[0099] In the present invention, an electronic paper display screen is formed by the above-mentioned electronic paper backplane and wiring module, and an electronic paper display screen shell, and can drive all series graphic blocks 21 on a series circuit through one driving port, thereby achieving the purpose of one driving port driving multiple graphic blocks, thereby being able to display more graphic blocks under a limited number of driving ports, saving the driving port resources of the driving module, and enriching the picture display effect of the electronic paper display screen, thereby improving the competitiveness of the electronic paper display screen.

[0100] In this embodiment, by electrically connecting the wiring module to an external control device or an external power source, display control of a plurality of independent graphic blocks and a plurality of series-connected display blocks can be implemented, thereby meeting corresponding display requirements.

[0101] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0102] The present invention divides a plurality of graphic blocks into a plurality of series graphic blocks 21 forming a plurality of series circuits and a plurality of independent graphic blocks according to different preset characteristic requirements, and then electrically connects each series circuit and each independent graphic block to different drive ports respectively, so that all the series graphic blocks 21 on a series circuit can be driven by one drive port, and the purpose of one drive port driving multiple graphic blocks is achieved, so that more graphic blocks can be displayed under a limited number of drive ports, saving the drive port resources of the drive module, enriching the picture display effect, and improving the competitiveness of the product.
