Description

Technical Field

[0001] The present application relates to the technical field of electronic paper, and in particular to a pen-segment type electronic paper three-dimensional graphic display device and method. Background Art

[0002] An electronic paper display is a paper-thin, soft, erasable display that can continuously switch and refresh displayed content like an ordinary LCD display, and is more power-efficient than an LCD display. Therefore, electronic paper displays are gradually being widely used in our lives.

[0003] In the related art, the pen-segment electronic paper display can only display simple patterns such as text, letters, numbers, etc. that lack three-dimensionality. At the same time, the displayed pattern has a relatively single color, which makes the overall display effect poor. Summary of the invention

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a pen-segment electronic paper three-dimensional graphic display device and method, which can make the displayed pattern more three-dimensional and the colors richer, thereby enhancing the display effect.

[0005] The first aspect of the present application provides a pen-segment electronic paper three-dimensional graphic display device, comprising a color filter layer; a VCOM electrode layer, which is arranged parallel to the color filter layer; a graphic electrode layer, which is arranged parallel to the VCOM electrode layer; and an electronic ink layer, which is arranged between the graphic electrode layer and the VCOM electrode layer, the electronic ink layer comprising black electrophoretic particles and white electrophoretic particles, and the black electrophoretic particles and the white electrophoretic particles move toward the direction approaching the VCOM electrode layer when the VCOM electrode layer and the graphic electrode layer are energized.

[0006] The pattern electrode layer includes a pattern electrode portion and a background electrode portion, and the pattern electrode portion and the background electrode portion are used for electrically connecting with a chip.

[0007] A first pattern area is formed on the pattern electrode portion, a second pattern area is formed on the color filter layer, and the first pattern area is flush with the second pattern area.

[0008] The background electrode portion is a rectangular electrode portion, a ring electrode portion or a trapezoidal electrode portion.

[0009] The first pattern area includes a first main graphic display area and a first shadow graphic display area. The first main graphic display area is located on one side of the first shadow graphic display area.

[0010] The second pattern area includes a second main graphic display area, a second shadow graphic display area, and an outline edge, the second main graphic display area is connected to the second shadow graphic display area, and the outline edge is set in the second shadow graphic display area.

[0011] The second aspect of the present application provides a pen-segment electronic paper three-dimensional graphic display method, including a chip controlling a VCOM electrode layer and a graphic electrode layer to apply voltage according to a preset screen swiping direction; under the action of the voltage, black electrophoretic particles and white electrophoretic particles in the electronic ink layer move toward the direction close to the VCOM electrode layer, thereby causing the color filter layer to display a pattern.

[0012] The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to the preset screen refresh direction and the first preset power-on time; the black electrophoretic particles in the electronic ink layer move toward the VCOM electrode layer until the black electrophoretic particles are completely close to the VCOM electrode layer, and the color filter layer displays a black pattern.

[0013] The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to the preset screen refresh direction and the first preset power-on time; the white electrophoretic particles in the electronic ink layer move toward the VCOM electrode layer until the white electrophoretic particles are completely close to the VCOM electrode layer, and the color filter layer displays a color pattern.

[0014] The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to the preset screen refresh direction and the second preset power-on time; when the white electrophoretic particles in the electronic ink layer move toward the direction close to the VCOM electrode layer, a gray scale is formed, thereby causing the color filter layer to display a shadow pattern.

[0015] The technical solution provided by this application may have the following beneficial effects:

[0016] When the VCOM electrode layer and the graphic electrode layer begin to apply voltage, the voltage application time is controlled so that the white electrophoretic particles cannot completely approach the VCOM electrode layer, forming a grayscale color between black and white. Since the reflectivity of the grayscale color is lower than that of pure white, the color seen through the color filter layer will be slightly darker, which can be used to display the shadow part of the pattern, making the pattern display more three-dimensional and improving the overall display effect.

[0031] Most of the current pen-segment electronic paper displays can only display simple text, letters, numbers or other patterns, and cannot display three-dimensional graphics, which results in a monotonous overall display effect.

[0032] In view of the above problems, the embodiments of the present application provide a pen-segment type electronic paper three-dimensional graphic display device, which can make the displayed pattern more three-dimensional and the colors richer, thereby enhancing the display effect.

[0033] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0034] Figure 1 It is a structural schematic diagram of a pen-segment type electronic paper three-dimensional graphic display device shown in an embodiment of the present application.

[0035] See also Figure 1 The pen-segment electronic paper three-dimensional graphic display device includes: a color filter layer 100, a VCOM electrode layer 200, a graphic electrode layer 300 and an electronic ink layer 400, the VCOM electrode layer 200 and the color filter layer 100 are arranged in parallel with each other; the graphic electrode layer 300 and the VCOM electrode layer 200 are arranged in parallel with each other; the electronic ink layer 400 is arranged between the graphic electrode layer 300 and the VCOM electrode layer 200, and the electronic ink layer 400 includes black electrophoretic particles 410 and white electrophoretic particles 420, and the black electrophoretic particles 410 and the white electrophoretic particles 420 move toward the direction close to the VCOM electrode layer 200 when the VCOM electrode layer 200 and the graphic electrode layer 300 are powered on.

[0036] It should be noted that the black electrophoretic particles 410 and the white electrophoretic particles 420 are located in the electronic ink film 430. The chip controls the black electrophoretic particles 410 and the white electrophoretic particles 420 in the electronic ink layer 400 to move up and down in the electronic ink film 430 by applying voltage through the graphic electrode layer 300 and the VCOM electrode layer 200. When the black electrophoretic particles 410 are close to the color filter layer 100, the black electrophoretic particles 410 absorb light, so the color filter layer 100 is still black. When the white electrophoretic particles 420 are close to the color filter layer 100, the color filter layer 100 observed is the color of the graphic because white can reflect light. When the shadow part of the pattern needs to be displayed, the color filter layer 100 is first made to observe black, and then a white voltage is applied, but the voltage application time can be shortened so that the white electrophoretic particles 420 are not completely close to the VCOM electrode layer 200 side, thereby forming a grayscale color between black and white. Since the reflectivity of the grayscale color is lower than that of pure white, the color seen through the color filter layer 100 will be slightly darker than the normal color, for example, the normal color is red, and the slightly dark color is dark red. Therefore, the above method can be used to display the shadow part of text, numbers, letters or other patterns.

[0037] Through the above method, the voltage application time is controlled so that the white electrophoretic particles 420 cannot completely approach the VCOM electrode layer 200, forming a grayscale color between black and white. Since the reflectivity of the grayscale color is lower than that of pure white, the color seen through the color filter layer 100 will be slightly darker, which can be used to display the shadow part of the pattern, thereby making the pattern display more three-dimensional and improving the overall display effect.

[0038] See also Figure 1 Furthermore, in one embodiment, the graphic electrode layer 300 includes a graphic electrode portion and a background electrode portion, and the graphic electrode portion and the background electrode portion are used to be electrically connected to the chip.

[0039] It should be noted that the background electrode portion and the pattern electrode portion are the same layer structure. On one pattern electrode layer, multiple pattern electrode portions and multiple background electrode portions can be arranged, and the multiple pattern electrode portions and multiple background electrode portions are electrically connected to the chip.

[0040] See also Figure 1 , Figure 2 and Figure 3, further, in one embodiment, a first pattern area 500 is provided on the graphic electrode portion, and a second pattern area 110 is provided on the color filter layer 100, and the first pattern area 500 and the second pattern area 110 are flush with each other. It should be noted that the pattern of the first pattern area 500 provided on the graphic electrode portion is the same as the pattern of the second pattern area 110 provided on the color filter layer 100, and the first pattern area 500 and the second pattern area 110 are flush in the vertical direction. Further, the background pattern on the background electrode portion and the second pattern area 110 on the color filter layer 100 will be hollowed out according to the shape of the pattern, and because the graphic electrode layer 300 and the color filter layer 100 are relatively thin, the graphic electrode layer 300 and the color filter layer 100 are generally arranged in parallel.

[0041] See also Figure 4 Further, in one embodiment, the background electrode portion is a rectangular electrode portion, a ring electrode portion or a trapezoidal electrode portion. Figure 4 , the background electrode part is a rectangular electrode part, which can be referred to Figure 4 The background electrode portion may be a ring electrode portion, which may refer to Figure 4 , the background electrode portion can be a triangular shaped electrode portion.

[0042] Please refer again Figure 2 and Figure 3 , further, in one embodiment, the second pattern area 110 includes a second main graphic display area 111, a second shadow graphic display area 112 and an outline edge 113, the second main graphic display area 111 is connected to the second shadow graphic display area 112, and the outline edge 113 is arranged in the second shadow graphic display area 112. Further, in one embodiment, the first pattern area 500 includes a first main graphic display area 510 and a first shadow graphic display area 520, and the first main graphic display area 510 is located on one side of the first shadow graphic display area 520.

[0043] It should be noted that the second main graphic display partition 111 is the main part of the graphic without the shadow part, the second shadow graphic display partition 112 is the shadow part of the graphic, the second main graphic display partition 111 and the second shadow graphic display partition 112 are connected together, and the outline edge 113 is to outline the shadow part of the graphic manually, so that the three-dimensional sense of the graphic is more obvious, and the first main graphic display partition 510 is closely adjacent to the first shadow graphic display partition 520, and the first main graphic display partition 510 and the first shadow graphic display partition 520 are aligned with the second main graphic display partition 111 and the second shadow graphic display partition 112 in the vertical direction. Further, the first shadow graphic display partition 520 and the second shadow graphic display partition 112 can be composed of multiple parts.

[0044] In order to better illustrate the overall display process, for example, if you need to display the three letters "S", "I", and "D" with a three-dimensional effect, you first need to design the corresponding letter patterns on the graphic electrode layer 300, where the main part of the letter "S" can be used as a graphic electrode, recorded as the first electrode part, and the shaded part of the graphic is connected into one piece as another graphic electrode, recorded as the second electrode part. Similarly, the letters "I" and "D" can be set according to the above method. Finally, all the graphic electrodes are electrically connected to the chip respectively.

[0045] Next, there are two ways to design the pattern and color of the color filter layer 100. In the first way, the main body of the letter "S" is set to dark red, the shadow part is set to light red, and the outline 113 is drawn in the light red area, that is, the second shadow graphic display partition 112, to enhance the three-dimensional effect. The dark red area, that is, the second main body graphic display partition 111 is the first electrode part, and the second shadow graphic display partition 112 is the second electrode part. When the chip is driven, the first electrode part and the second electrode part are driven at the same time, so that the white electrophoretic particles in the electronic ink layer are close to the VCOM electrode layer 200. In this way, the dark red and light red graphics can be seen through the color filter layer 100. Another way is to set the main body and the shadow part of the letter "S" to the same color. Since the first electrode part and the second electrode part are separated, that is, the first electrode part controls the electronic paper to display white, that is, the white electrophoretic particles are completely close to the VCOM electrode layer 200, and the main part of the color filter layer 100 appears red through the effect of the reflected white light, while the second electrode part controls the electronic paper to display a gray scale between black and white, that is, the white electrophoretic particles are not completely close to the VCOM electrode layer 200. In this way, the light reflection efficiency of the white electrophoretic particles is reduced, and the display brightness of the corresponding part of the color filter layer 100 will also be reduced, so that the display color will be dim, achieving the shadow effect of the letters, making the overall display effect more three-dimensional.

[0046] Corresponding to the aforementioned application function realization method embodiment, the present application also provides a corresponding embodiment of a pen-segment type electronic paper three-dimensional display method.

[0047] Figure 5 It is a method flow chart of the pen-segment type electronic paper 3D display method shown in an embodiment of the present application.

[0048] See also Figure 5 , a method for a pen segment type electronic paper 3D display method, comprising:

[0049] Step S101: The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to a preset screen refresh direction.

[0050] It should be noted that the preset screen refresh direction is determined according to the design of the background electrode part, wherein, please refer to Figure 3 The preset screen refresh direction can be refreshing from the leftmost background electrode part to the right, or refreshing from the middle background electrode part to both sides, or refreshing from the upper left corner of the electronic paper screen to the lower right corner, or refreshing from the center of the electronic paper screen to the surroundings. The above methods depend on the shape of the background electrode part.

[0051] Step S102 : The black electrophoretic particles and the white electrophoretic particles in the electronic ink layer move toward the VCOM electrode layer under the action of the voltage, thereby causing the color filter layer to display a pattern.

[0052] It should be noted that the black electrophoretic particles and the white electrophoretic particles move up and down in the electronic ink film under the action of voltage applied to the pattern electrode layer, so that the color filter layer displays patterns of different colors.

[0053] See also Figure 6 , Figure 6 One embodiment of a pen-segment type electronic paper 3D display method includes the following steps:

[0054] Step S201, the chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to a preset screen refresh direction and a first preset power-on time;

[0055] Step S202 : The black electrophoretic particles in the electronic ink layer move toward the VCOM electrode layer until the black electrophoretic particles are completely close to the VCOM electrode layer, and the color filter layer displays a black pattern.

[0056] It should be noted that the first preset power-on time is the normal power-on time. When the VCOM electrode layer and the graphic electrode layer release the voltage, the black electrophoretic particles move toward the VCOM electrode layer until the black electrophoretic particles are completely close to the VCOM electrode layer, and the color filter layer displays a black pattern.

[0057] See also Figure 7 , Figure 7 One embodiment of a pen-segment type electronic paper 3D display method includes the following steps:

[0058] Step S301: The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to a preset screen refresh direction and a first preset power-on time.

[0059] Step S302 : The white electrophoretic particles in the electronic ink layer move toward the VCOM electrode layer until the white electrophoretic particles are completely close to the VCOM electrode layer, and the color filter layer displays a color pattern.

[0060] It should be noted that by changing the driving waveform, the white electrophoretic particles move in the electronic ink film toward the VCOM electrode layer. When the white electrophoretic particles are completely close to the VCOM electrode layer, a color pattern is displayed through the color filter layer.

[0061] See also Figure 8 , Figure 8 One embodiment of a pen-segment type electronic paper 3D display method includes the following steps:

[0062] Step S401: The chip controls the VCOM electrode layer and the graphic electrode layer to apply voltage according to a preset screen refresh direction and a second preset power-on time.

[0063] Step S402 : When the white electrophoretic particles in the electronic ink layer move toward the direction close to the VCOM electrode layer, a gray scale is formed, thereby making the color filter layer display a shadow pattern.

[0064] It should be noted that the second preset power-on time is shorter than the first preset power-on time. By shortening the time for applying the voltage required to display white, the white electrophoretic particles move toward the direction close to the VCOM electrode layer, but do not completely reach the VCOM electrode layer, thereby forming a grayscale color between black and white, and its reflectivity is lower than pure white. Therefore, a darker color can be seen through the color filter layer, which can be used as the shadow part of the display pattern, making the display effect more three-dimensional.
