Description

Technical Field

[0001] This invention relates to the field of electronic paper display technology, and in particular to a color electronic paper display and its driving method. Background Technology

[0002] Display panels offer advantages such as thinness, durability, and low power consumption, which are energy-efficient and environmentally friendly. However, they require a backlight, resulting in a thicker module and higher cost. Electronic paper displays (reflective displays) have emerged as a solution to meet the needs of the general public. Unlike LCD displays, which require a backlight, electronic paper displays can use external light sources to display images. Therefore, even in strong sunlight, the information on the electronic paper remains clearly visible without viewing angle issues. Furthermore, due to their energy efficiency, high reflectivity, and high contrast ratio, electronic paper displays are now widely used in e-readers (such as e-books and e-newspapers) and other electronic components (such as price tags).

[0003] Existing electronic paper displays typically employ E-Ink microcapsule technology (microcapsule electronic ink technology), SiPix microcup technology (microcup electrophoretic display technology), Bridgestone electronic liquid powder technology, Cholesteric Liquid Crystal Display (CLCD) technology, microelectromechanical systems (MEMS) technology, or electrowetting technology. However, existing electronic paper display technologies are less mature than liquid crystal display technologies, have lower mass production efficiency, higher manufacturing costs, and can only achieve black and white displays.

[0004] Figure 1 This is a schematic diagram of the structure of a color electronic paper display in its initial state in the prior art. Figure 2 This is a schematic diagram of the structure of a color electronic paper display in the display state in existing technology. For example... Figure 1 and Figure 2 As shown, existing electronic paper displays require an additional color filter substrate 1 to achieve color display. Existing color electronic paper displays include a color filter substrate 1, an array substrate 2 disposed opposite to the color filter substrate 1, and an ink capsule 3 located between the color filter substrate 1 and the array substrate 2. The principle is to use ambient light to pass through the color resist layer 4 on the color filter substrate and filter the light, and then display the image after being reflected by the white particles in the ink capsule 3. However, the use of conventional color filter substrate 1 and array substrate 2 in existing color electronic paper displays will increase the thickness of the color electronic paper display, which is not conducive to the development of thinner and lighter designs. Moreover, the bonding of the color filter substrate 1 and the array substrate 2 requires high assembly and alignment accuracy. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the prior art, the purpose of this invention is to provide a color electronic paper display and driving method to solve the problems of the thickness of the color electronic paper display and the need for high alignment accuracy in the prior art.

[0006] The objective of this invention is achieved through the following technical solution: This invention provides a color electronic paper display, including an array substrate and an electronic ink film attached to the side of the array substrate away from the external environment. The electronic ink film contains ink capsules, and each ink capsule contains black ink particles and white ink particles of opposite polarity. The array substrate has a color resist layer and a pixel electrode located on the side of the color resist layer facing the electronic ink film. The side of the electronic ink film away from the array substrate has a first common electrode that cooperates with the pixel electrode. The color resist layers of two adjacent different colors partially overlap.

[0007] Furthermore, the array substrate is provided with multiple scan lines, multiple data lines, and multiple thin-film transistors. The multiple scan lines and multiple data lines are mutually insulated and cross each other to form multiple pixel units. Each pixel unit is provided with a thin-film transistor and a pixel electrode. The pixel electrode is electrically connected to the scan line and the data line adjacent to the thin-film transistor through the thin-film transistor.

[0008] Furthermore, a second common electrode is provided on the array substrate, the second common electrode is located between the color resist layer and the pixel electrode, and a storage capacitor is formed between the second common electrode and the pixel electrode.

[0009] Furthermore, the array substrate is provided with a common electrode wire, which is located on a different layer from the second common electrode and is in conductive contact.

[0010] Furthermore, the common electrode wire and the scan line are located on the same layer, and the projection portions of the common electrode wire and the data line on the array substrate overlap; Alternatively, the common electrode conductor and the data line are located on the same layer, and the projection portions of the common electrode conductor and the scan line on the array substrate overlap.

[0011] Furthermore, the common electrode wire is located on the side of the second common electrode facing the pixel electrode and is in direct contact with the surface of the second common electrode. The multiple common electrode wires have a grid structure and correspond to the scan line and the data line.

[0012] Furthermore, both the scan lines and the data lines have an anti-reflective layer on the surface facing the external environment.

[0013] Furthermore, the pixel unit includes a red pixel unit, a green pixel unit, a blue pixel unit, and a white pixel unit, the color resist layer corresponds to the red pixel unit, the green pixel unit, and the blue pixel unit, and the array substrate is transparent in the area corresponding to the white pixel unit.

[0014] Furthermore, the surface of the color resist layer facing the pixel electrode is covered with a planarization layer, and the second common electrode is disposed on the surface of the planarization layer facing the pixel electrode.

[0015] This application also provides a driving method for a color electronic paper display, used to drive the color electronic paper display as described above, the driving method comprising: Provides image signals for displaying the screen; The image signal data signal is reversed in position before being transmitted to the color electronic paper display.

[0016] The beneficial effects of this invention are as follows: by placing the array substrate on the side of the electronic ink film facing the external environment and placing the color resist layer on the array substrate, the array substrate can act as a color filter substrate, reducing the thickness of the display; moreover, by placing the color resist layer directly on the array substrate, there is no alignment problem, which solves the problem that the bonding of the color filter substrate and the array substrate in existing displays requires high alignment accuracy; in addition, by partially overlapping the color resist layers of two adjacent different colors, the problem of color mixing between pixel units of two adjacent different colors can be avoided. Therefore, there is no need to set a black matrix, simplifying the manufacturing process and reducing manufacturing costs. Attached Figure Description

[0034] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation methods, structures, features, and effects of the color electronic paper display and driving method proposed according to the present invention: [Example 1] Figure 3 This is a schematic diagram of the structure of the color electronic paper display in the initial state in Embodiment 1 of the present invention. Figure 4 This is a schematic diagram of the structure of the color electronic paper display in the display state according to Embodiment 1 of the present invention. Figure 5 This is a schematic diagram of the planar structure of the array substrate in Embodiment 1 of the present invention. Figure 6 This is a schematic diagram of the planar structure of the color resist layer in Embodiment 1 of the present invention. Figure 7 This is a schematic diagram of the cross-sectional structure of the array substrate in Embodiment 1 of the present invention. Figure 8 This is a schematic diagram of the planar structure of a single pixel unit in Embodiment 1 of the present invention.

[0035] like Figures 3 to 8 As shown, a color electronic paper display provided in Embodiment 1 of the present invention includes an array substrate 10 and an electronic ink film 20 attached to the side of the array substrate 10 away from the external environment. Specifically, the array substrate 10 is an inverted structure and is disposed on the light-emitting side of the electronic ink film 20. The light path is: ambient light → array substrate 10 → color resist layer 14 → electronic ink film 20 → color resist layer 14 → array substrate 10 → human eye. The electronic ink film 20 contains ink capsules 21. Each ink capsule 21 contains black ink particles 211 and white ink particles 212 of opposite polarities. By providing electric fields in different directions to the ink capsules 21, the black particles 211 and white particles 212 can move in corresponding directions. For example, black particles 211 are negatively charged, and white particles 212 are positively charged, causing white particles 212 to move in the direction of the electric field, and black particles 211 to move in the opposite direction of the electric field. If an electric field is applied upwards, white particle 212 moves upwards and black particle 211 moves downwards; if an electric field is applied downwards, white particle 212 moves downwards and black particle 211 moves upwards. Alternatively, black particle 211 can be positively charged and white particle 212 negatively charged, causing black particle 211 to move in the direction of the electric field and white particle 212 to move in the opposite direction.

[0036] An array substrate 10 has a color resist layer 14 and a pixel electrode 161 located on the side of the color resist layer 14 facing the electronic ink film 20. The side of the electronic ink film 20 away from the array substrate 10 has a first common electrode 22 that cooperates with the pixel electrode 161. Adjacent color resist layers 14 of two different colors partially overlap. The first common electrode 22 is a planar electrode that covers the entire surface of the electronic ink film 20. The pixel electrode 161 is a block electrode corresponding to a pixel unit P. Each pixel electrode 161 corresponds to one pixel unit P, and one pixel unit P can correspond to one or more ink capsules 21. By controlling the voltage polarity on the pixel electrode 161, the direction of the electric field between the pixel electrode 161 and the first common electrode 22 is controlled, thereby controlling the ink capsule 21 to switch between a black state (light-absorbing state) and a white state (reflective state). For example, if a 0V common voltage is applied to the first common electrode 22, and a positive voltage is applied to the pixel electrode 161, the electric field direction between the pixel electrode 161 and the first common electrode 22 is towards the first common electrode 22; if a negative voltage is applied to the pixel electrode 161, the electric field direction between the pixel electrode 161 and the first common electrode 22 is towards the pixel electrode 161. Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the color resist layer 14 includes a red color resist 141, a green color resist 142, and a blue color resist 143, and correspondingly forms red pixel units, green pixel units, and blue pixel units. The adjacent red color resist 141 and green color resist 142 partially overlap, the adjacent green color resist 142 and blue color resist 143 partially overlap, and the adjacent blue color resist 143 and red color resist 141 partially overlap. This avoids the problem of color mixing between adjacent pixel units of two different colors. Therefore, there is no need to set a black matrix, which simplifies the manufacturing process and reduces the manufacturing cost.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, the array substrate 10 has multiple scan lines 111, multiple data lines 131, and multiple thin-film transistors (TFTs). The scan lines 111 and data lines 131 are mutually insulated and intersecting to form multiple pixel units P. Each pixel unit P has a TFT and a pixel electrode 161. The pixel electrode 161 is electrically connected to the scan lines 111 and data lines 131 of adjacent TFTs through the TFTs. The TFTs include a gate 112, an active layer 121, a source 132, and a drain 133. The gate 112 is located on the same layer as the scan lines 111 and is electrically connected. The gate 112 and the active layer 121 are isolated by a gate insulating layer 101. The source 132 is located on the same layer as the data lines 131 and is electrically connected. The drain 133 is electrically connected to the pixel electrode 161 through a contact hole. The gate 112 and the scan line 111 are both etched from the first metal layer 11, and the data line 131, the source 132 and the drain 133 are all etched from the second metal layer 13.

[0038] Optionally, the overlapping areas of two adjacent color resist layers 14 of different colors correspond to the scan line 111, data line 131, and thin-film transistor (TFT) to avoid affecting the pixel aperture ratio and to enhance the effect of preventing color mixing. When corresponding to the TFT, the light leakage effect of the active layer 121 in the TFT can be reduced, thereby improving device performance.

[0039] In this embodiment, as Figure 7 and Figure 8As shown, a second common electrode 151 is provided on the array substrate 10. The second common electrode 151 is located between the color resist layer 14 and the pixel electrode 161. The second common electrode 151 is a planar electrode covering the entire surface and is isolated from the pixel electrode 161 by a second insulating layer 104. A storage capacitor is formed between the second common electrode 151 and the pixel electrode 161. The second common electrode 151 is etched from the first transparent conductive layer 15, and the pixel electrode 161 is etched from the second transparent conductive layer 16. Furthermore, the scan line 111 and the data line 131 are provided with an anti-reflective layer on the surface facing the external environment. The anti-reflective layer can be made of MoOx to achieve a blackening effect and improve the display quality (avoiding metallic reflective bright spots).

[0040] Optionally, a planarization layer 103 covers the surface of the color resist layer 14 facing the pixel electrode 161, and the second common electrode 151 is disposed on the surface of the planarization layer 103 facing the pixel electrode 161. Further, a first insulating layer 102 is provided on the array substrate 10 to cover the data line 131, the source electrode 132, the drain electrode 133, and the active layer 121. That is, the first insulating layer 102, the color resist layer 14, the planarization layer 103, the second common electrode 151, the second insulating layer 104, and the pixel electrode 161 are sequentially stacked on the side facing the electronic ink film 20.

[0041] The array substrate 10 can be made of materials such as glass, acrylic, and polycarbonate. The first common electrode 22, the second common electrode 151, and the pixel electrode 161 can be made of transparent metals such as indium tin oxide (ITO) or indium zinc oxide (IZO). The scan line 111, gate 112, data line 131, source 132, and drain 133 can be made of metallic materials, such as copper (Cu), silver (Ag), chromium (Cr), molybdenum (Mo), aluminum (Al), titanium (Ti), manganese (Mn), and nickel (Ni). Of course, the first common electrode 22 can also be made of a metallic material.

Figure 10 This is a schematic diagram of the structure of the color electronic paper display in the display state in Embodiment 2 of the present invention. Figure 11 This is a schematic diagram of the planar structure of the color resist layer in Embodiment 2 of the present invention. Figures 9 to 11 As shown, the color electronic paper display provided in Embodiment 2 of the present invention is similar to that in Embodiment 1. Figures 3 to 8 The color electronic paper displays in () are basically the same, except that: In this embodiment, pixel unit P includes red pixel unit, green pixel unit, blue pixel unit, and white pixel unit. Color resist layer 14 corresponds to the red, green, and blue pixel units. The array substrate 10 is transparent in the area corresponding to the white pixel unit. Specifically, red color resist 141 corresponds to the red pixel unit, green color resist 142 corresponds to the green pixel unit, and blue color resist 143 corresponds to the blue pixel unit. The area of ​​the array substrate 10 corresponding to the white pixel unit is filled by a planarization layer 103. By setting independent white pixel units, the brightness of the color electronic paper display can be increased to improve contrast. Furthermore, the white pixel unit is individually controlled, allowing it to be turned on at high contrast and off during normal display to avoid affecting color accuracy.

[0043] Optionally, red, green, blue, and white pixel units can be arranged in a mosaic structure, meaning that any two adjacent pixel units P have different colors, in order to improve the display effect.

[0044] Those skilled in the art should understand that the remaining structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Figure 13 This is one of the schematic diagrams of the planar structure of a single pixel unit in Embodiment 3 of the present invention. Figure 14 This is the second schematic diagram of the planar structure of a single pixel unit in Embodiment 3 of the present invention. For example... Figures 12 to 14 As shown, the color electronic paper display provided in Embodiment 3 of the present invention is similar to that in Embodiment 1 (… Figures 3 to 8 Example 2 Figures 9 to 11 The color electronic paper displays in () are basically the same, except that: In this embodiment, a common electrode wire 171 is provided on the array substrate 10. The common electrode wire 171 and the second common electrode 151 are located on different layers and are in conductive contact, thereby reducing the impedance of the second common electrode 151 and reducing the driving power.

[0046] In this embodiment, the common electrode wire 171 and the scan line 111 are located on the same layer, that is, the gate 112, the scan line 111, and the common electrode wire 171 are all etched from the first metal layer 11, thereby simplifying the manufacturing process and reducing manufacturing costs. Figure 13 As shown, the common electrode conductor 171 surrounds the edge of the pixel electrode 161 and is completely offset from the projections of the scan line 111 and the data line 131 onto the array substrate 10. Figure 14As shown, the projections of the common electrode wire 171 and the data line 131 on the array substrate 10 overlap, thereby increasing the aperture ratio.

[0047] Of course, in other embodiments, the common electrode wire 171 may also be located on the same layer as the data line 131, and the projection portions of the common electrode wire 171 and the scan line 111 on the array substrate 10 may overlap, that is, the data line 131, the source 132, the drain 133 and the common electrode wire 171 are all etched by the second metal layer 13.

[0048] Those skilled in the art should understand that the remaining structures and working principles of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be repeated here.

Figure 16 This is a schematic diagram of the planar structure of the common electrode wire in Embodiment 4 of the present invention. Figure 15 and Figure 16 As shown, the color electronic paper display provided in Embodiment 4 of the present invention is similar to that in Embodiment 1 ( Figures 3 to 8 Example 2 Figures 9 to 11 The color electronic paper displays in () are basically the same, except that: In this embodiment, a common electrode wire 171 is provided on the array substrate 10. The common electrode wire 171 and the second common electrode 151 are located on different layers and are in conductive contact, thereby reducing the impedance of the second common electrode 151 and reducing the driving power.

[0050] In this embodiment, the common electrode wires 171 are located on the side of the second common electrode 151 facing the pixel electrode 161 and are in direct contact with the surface of the second common electrode 151. Multiple common electrode wires 171 form a mesh structure and correspond to the scan line 111 and the data line 131. Specifically, in this embodiment, the common electrode wires 171 are etched from a third metal layer 17, which directly covers the surface of the second common electrode 151 facing the pixel electrode 161, thereby allowing the common electrode wires 171 to have a mesh structure to avoid affecting the aperture ratio.

[0052] Figure 17 This is a schematic diagram of the driving circuit in the color electronic paper display of the present invention. Figure 17As shown, a driving method for a color electronic paper display is provided for driving the color electronic paper display as described above. The driving circuit for the color electronic paper display includes a processor (MCU), a timing controller (TCON), a gate driver chip, and a source driver chip. The processor is electrically connected to the timing controller, and both the gate driver chip and the source driver chip are electrically connected to the timing controller. The image signal output by the processor is processed by the timing controller and then transmitted to the gate driver chip and the source driver chip respectively. Finally, the gate driver chip and the source driver chip drive the color electronic paper display to show the corresponding image.

[0053] The driving method includes: The image signal for the display screen is provided; specifically, the image signal for the display screen is provided by the processor. The image signal data signal undergoes position inversion processing (e.g., low level → high level, high level → low level of image data) before being transmitted to the color electronic paper display. Specifically, after the image signal is processed by the timing controller, it is transmitted to the gate driver chip and the source driver chip respectively. Finally, the gate driver chip and the source driver chip drive the color electronic paper display to show the corresponding image. The position inversion processing of the image signal data signal can be performed by the timing controller or by the source driver chip. Since the array substrate 10 in this application has an inverted structure, the image displayed by the conventional driving method is mirrored. Therefore, position inversion (mirroring) processing is required to display a normal image.
