Abstract
Description
[Technical Field]
[0001] The present invention relates to a display device, and in particular to a full-color display device that improves opening ratio and contrast. [Previous Technology]
[0002] Cholesteric Liquid Crystal Display technology is compatible with existing liquid crystal display panel (Liquid Crystal Display) production methods and has become the mainstream of reflective display technology in recent years because of its excellent characteristics of easy implementation of full color, high reflectivity, power saving and eye protection. In the application of active array cholesterol liquid crystal display panels, the liquid crystal is mainly controlled by the electric field generated between the common electrodes of the upper substrate and the pixel electrodes of the lower panel to control the direction of liquid crystal molecules. However, there will be a voltage difference between the scanning line and data line and the pixel electrode to form an electric field. The improvement of the opening rate is greatly limited because there is a large overlap area between the shading element and the pixel electrode;
[0003] The current active cholesterol LCD display panel has a data line width of 4.5 microns, but the dark-state leakage width is greater than 20 microns. The main cause of the problem is light leakage caused by the rotation of liquid crystal molecules caused by the electric field between the data line and the pixel electrodes. In view of this, there is currently a lack of a display device on the market that can effectively increase the opening rate and contrast. [Invention Contents]
[0004] Therefore, the object of the present invention is to provide a display device that minimizes the black matrix (BM) light-blocking width from a single-color cholesteric liquid crystal display panel by means of an electric field shielding electrode structure. Then, various BM patterns are used to completely or partially shield the data lines and the electric field shielding electrodes. The light-transmitting area of the electric field shielding electrodes increases the aperture ratio, and the surface of the metal line area reflects light, thereby improving the efficiency of recycling and reusing external incident light. Furthermore, by combining these R, G, and B cholesteric liquid crystal display panels with different optical reflection and transmission characteristics in various combinations, during the three-piece lamination process, not only can the aperture ratio loss caused by the large BM light-blocking width and insufficient lamination precision be significantly reduced, but also various full-color active cholesteric liquid crystal display devices with varying degrees of improvement in aperture ratio and contrast can be obtained, thus solving the problems of excessively small aperture ratio and low contrast in the prior art.

Implementation Method
[0025] Several embodiments of the present invention will now be described with reference to the drawings. For clarity, many practical details will be set forth in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be depicted in the drawings in a simple schematic manner; and repeated elements may be denoted by the same number.
[0026] Furthermore, in this document, when a component (or unit or module, etc.) is "connected" to another component, it can mean that the component is directly connected to the other component, or it can mean that the component is indirectly connected to the other component, that is, there is another component between the component and the other component. Only when it is explicitly stated that a component is "directly connected" to another component does it mean that there is no other component between the component and the other component. The terms "first," "second," "third," etc., are only used to describe different components and do not limit the components themselves. Therefore, the first component can also be referred to as the second component. Moreover, the combinations of components / units / circuits in this document are not combinations that are generally known, conventional, or customary in this field. Whether the components / units / circuits themselves are customary cannot be used to determine whether their combination relationship is easily completed by someone of ordinary knowledge in the art.
[0027] The display device of the present invention uses optical adhesive (OCA) to sequentially bond red, green, and blue active-matrix cholesteric liquid crystal panels. Each color active-matrix cholesteric liquid crystal display panel includes a top plate, an active-matrix display panel area, a cholesteric liquid crystal layer, and a driving circuit. The switching element of the active-matrix array is a thin-film transistor (TFT), including but not limited to amorphous silicon (a-Si) TFTs, oxide semiconductor TFTs (such as indium gallium zinc oxide (IGZO) or others), or low-temperature polycrystalline silicon TFTs. The driving circuit provides drive signals for the scan lines and data lines using COF (Chip On Flex), IC+FPC (Flexible Printed Circuit), or GOA (Gate On Array) methods. Each pixel within the active-matrix display panel area includes a TFT, scan lines (Gate lines), data lines, common electrode lines (Com lines), pixel electrodes, and electric field shielding electrodes. The electrical connection of the electric field shielding electrode can be a common electrode (Com line) or a floating connection.
[0028] Please refer to Figures 1A, 1B, and 1C together, wherein Figure 1A is a schematic diagram illustrating the pixel structure of the display device; Figure 1B is a schematic diagram illustrating a first structure in which the electric field shielding electrode 106 of the present invention is electrically connected in a floating manner; and Figure 1C is a schematic diagram illustrating a second structure in which the electric field shielding electrode 106 of the present invention is electrically connected in a floating manner. The pixel structure of the display device in Figure 1A includes a substrate 101, a gate insulating layer 102, a data line 103, a passivation layer 104 (such as silicon nitride), and a pixel electrode 105. The first floating structure in Figure 1B includes a substrate 101, a gate insulating layer 102, a data line 103, a passivation layer 104, a pixel electrode 105, and an electric field shielding electrode 106. The first type of floating structure adds an electric field shielding electrode 106 to the substrate 101. The width of the electric field shielding electrode 106 is greater than the width of the data line 103, and the two are separated by a distance DA (DA≥1.5 micrometers). With the process tolerance of the upper and lower layers ensured, the distance DC = distance DA + distance DB≥3 micrometers, thereby achieving the purpose of light shielding.
[0029] The second floating-ground structure in Figure 1C includes a substrate 101, a gate insulating layer 102, a data line 103, a passivation layer 104, a pixel electrode 105, an electric field shielding electrode 106, and a hole 107. The second floating-ground structure incorporates a hole in the electric field shielding electrode 106 to reduce the parasitic capacitance between the data line 103 and the electric field shielding electrode 106, and to reduce electrostatic discharge during fabrication. Furthermore, since the electric field shielding electrode 106 is not connected to any other leads, it does not cause crosstalk to other electrodes. The principle of electric field shielding is as follows: First, the data line 103 is the common voltage source for both the pixel electrode 105 and the electric field shielding electrode 106, and the voltage difference creates two electric fields in opposite directions. Next, a photosensitive organic resin planarization layer is added between the passivation layer 104 and the pixel electrode 105 to increase the distance between the data line 103 and the pixel electrode 105. These two methods can significantly reduce the electric field strength of the data line 103 to the pixel electrode 105, which means reducing the width and degree of light leakage. In other words, the width of the BM blocking the edge of the pixel electrode 105 is also reduced, which can significantly improve the aperture ratio and contrast.
[0030] For a single-color cholesteric liquid crystal display panel, the present invention proposes the following configuration: the first layer of the upper substrate is BM, followed by the coating of a protective material (Overcoat; OC) as a planarization layer to block ions that may be released from the BM material. Then, a light-transmitting conductive material (such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), etc.) is sputtered onto the OC. Finally, a photosensitive spacer is formed to support the cell gap. A black matrix is provided on the upper substrate to shield the lower substrate TFTs, preventing photo-induced leakage current from causing switching failure after the TFT channels are illuminated. Electric field shielding electrodes 106 are provided in the array substrate of the lower substrate, and can be extensions of the common electrode (Com line) or floating.
[0031] Please refer to Figures 2A, 3A, and 4A together. Figure 2A is a schematic diagram of the first pixel module of the display device of the present invention, wherein the electric field shielding electrode S11 is transmissive; Figure 3A is a schematic diagram of the second pixel module of the display device of the present invention, wherein the electric field shielding electrode S11 is reflective; and Figure 4A is a schematic diagram of the third pixel module of the display device of the present invention, wherein the electric field shielding electrode S11 is semi-transmissive and semi-reflective. Each display panel of the display device of the present invention includes a plurality of pixel modules, including a first pixel module, a second pixel module, and a third pixel module. Each pixel module includes a scan line S10, a data line S09, a switching element SW, a pixel electrode S07, and an electric field shielding electrode S11. Scan line S10 is positioned below pixel electrode S07, data line S09 is positioned below pixel electrode S07, switching element SW is connected between scan line S10 and data line S09, and electric field shielding electrode S11 is partially positioned below data line S09. Scan line S10 is perpendicular to data line S09.
[0032] When the electric field shielding electrode S11 is a penetrating type, its pattern is entirely made of light-transmitting conductive material, such as ITO or IZO; in other words, this electric field shielding electrode S11 is made of a light-transmitting conductive material, and the light-transmitting conductive material is light-transmitting.
[0033] When the electric field shielding electrode S11 is reflective, its pattern is entirely metal; in other words, this electric field shielding electrode S11 is made of a metal material that is opaque.
[0034] When the electric field shielding electrode S11 is semi-transparent and semi-reflective, a portion of its pattern is metallic, while another portion is translucent. Specifically, the electric field shielding electrode S11 includes a transverse electrode portion S11a and a longitudinal electrode portion S11b. The transverse electrode portion S11a is perpendicular to the data line S09 and is made of a metallic material that is opaque. The longitudinal electrode portion S11b is perpendicular to the transverse electrode portion S11a and parallel to the data line S09. The longitudinal electrode portion S11b is made of a light-transmitting conductive material that is light-transmitting. In Figure 4A, the electric field shielding electrode S11 parallel to the scan line S10 (i.e., the transverse electrode portion S11a) is metallic, while the electric field shielding electrode S11 parallel to the data line S09 (i.e., the longitudinal electrode portion S11b) is translucent. In other embodiments, the transverse electrode portion is translucent, and the longitudinal electrode portion is metallic. This invention is not limited to the above.
[0035] Please refer to Figures 2A, 2B, 2C, 2D, and 2E together, wherein Figure 2B is a schematic diagram illustrating the first black matrix S051 of the present invention; Figure 2C is a schematic diagram illustrating the first pixel module of the display device of the present invention combined with the first black matrix S051; Figure 2D is a cross-sectional view along line AA in Figure 2C; and Figure 2E is a cross-sectional view along line BB in Figure 2C. A first pixel unit 1a2 of the display panel of the display device includes a first pixel module and a first black matrix S051. The first black matrix S051 is disposed above the scan line S10, the data line S09, the pixel electrode S07, and the electric field shielding electrode S11, that is, the pixel electrode S07 is disposed below the first black matrix S051. In one embodiment, the first black matrix S051 shields the data line S09 and the electric field shielding electrode S11 along a direction (axial direction Z), as shown in Figure 2D. The first black matrix S051 blocks the scan line S10 and the electric field shielding electrode S11 along the Z-axis, as shown in Figure 2E. In other words, the first black matrix S051 completely blocks the scan line S10, the data line S09, and the electric field shielding electrode S11 along this direction (Z-axis).
[0036] The array substrate pixel in Figure 2A is formed by sputtering a first transparent conductive layer ITO1 (such as ITO, IZO, or other transparent conductive materials) on the array substrate, and then forming an electric field shielding electrode S11 through a first photolithography and etching process. This electrode includes two main parts: parallel scan lines S10 and data lines S09. Next, a first metal layer M1 (any conductive metal material such as molybdenum-aluminum alloy, copper, or copper alloy) is sputtered, and then the scan lines S10 and the gate of the TFT (SW) are formed through a second photolithography and etching process. Finally, chemical vapor deposition (CVD) is used to form the shielding electrode. Deposition: A gate insulating layer (such as SiNx) / a-Si / n+ layer (GIN) is deposited using CVD. A third photolithography and etching process forms an island-shaped GIN pattern. The area outside the island GIN pattern is then selectively etched to remove a-Si / n+, leaving only the gate insulating layer. Next, a second metal layer M2 (any conductive metal such as molybdenum-aluminum alloy, copper, or copper alloy) is sputtered. A fourth photolithography and etching process forms the source and drain of the TFT (SW) and the data line S09. An n+ etching process removes n+ and part of the a-Si layer, forming the thin-film transistor channel (TFT Channel). A Pas layer (passivation layer such as silicon nitride) is then deposited using CVD to protect the TFT channel. Finally, a photosensitive organic resin layer (OG layer) is coated onto the lower substrate, followed by a fifth photolithography process to form a flattening layer and vias. The process involves a sixth photolithography and etching process to create a drain, a connection hole between the pixel electrode S07 and the surrounding metal signal lines. Following this, a second transparent conductive layer, ITO2 (such as ITO, IZO, etc.), is sputtered, and a seventh photolithography and etching process is used to form the pixel electrode S07. This is the fabrication process for a seven-mask array substrate. In other embodiments, the OG layer can be omitted to reduce the number of masks on the array substrate and production costs, while also reducing light transmittance loss when passing through the OG layer.
[0037] When the electric field shielding electrode S11 is made of a light-transmitting material such as ITO or IZO, the electrical connection can be floating or connected to the Com signal. In addition, drilling a hole in the electric field shielding electrode S11 can reduce the parasitic capacitance between the data line S09 and the electric field shielding electrode S11 and reduce electrostatic discharge damage that occurs during the fabrication process; the area of the pixel electrode S07 projected onto the electric field shielding electrode S11 can be used as a storage capacitor.
[0038] The combination of the array pixels in Figure 2A and the first black matrix S051 pattern in Figure 2B can obtain the pixel combination in Figure 2C. The cross-section AA of the data line S09 position of the pixel is shown in Figure 2D; the cross-section BB of the scan line S10 position of the pixel is shown in Figure 2E. In the array substrates of Figures 2C, 2D and 2E, the incident light can only enter and exit through the edge of the first black matrix S051 pattern. Although this avoids glare caused by the reflection of ambient light by the data line S09, it also reduces the aperture ratio of the pixel. The distance between the first black matrix S051 on the upper plate and the edge of the metal line on the lower plate is greater than or equal to (≥) 3 micrometers. The width of the overlapping portion of the pixel electrode S07 and the electric field shielding electrode S11 on the lower plate is greater than or equal to (≥) 1.5 micrometers. The distance between the edges of the overlapping area of the data line S09 and part of the electric field shielding electrode S11 is greater than or equal to (≥) 1.5 micrometers. Furthermore, the first black matrix S051, pixel electrode S07, data line S09, and electric field shielding electrode S11 are stacked along this direction (axial direction Z) to form a light-transmitting aperture LH. The light-transmitting aperture LH has a first light-transmitting aperture diameter D1 along a first radial direction (axial direction X), and a second light-transmitting aperture diameter D2 along a second radial direction (axial direction Y). The first radial direction is perpendicular to the second radial direction, and both the first and second radial directions are perpendicular to this direction. Both the first light-transmitting aperture diameter D1 and the second light-transmitting aperture diameter D2 are determined by the first black matrix S051.
[0039] Please refer to Figures 3A, 3B, 3C, 3D, and 3E together, wherein Figure 3B is a schematic diagram illustrating the second black matrix S052 of the present invention; Figure 3C is a schematic diagram illustrating the second pixel module of the display device of the present invention combined with the second black matrix S052; Figure 3D is a cross-sectional view along line AA in Figure 3C; and Figure 3E is a cross-sectional view along line BB in Figure 3C. One of the display panels of the display device, a second pixel unit 2a2, includes a second pixel module and a second black matrix S052. The second black matrix S052 is disposed above the scan line S10, the data line S09, the pixel electrode S07, and the electric field shielding electrode S11, that is, the pixel electrode S07 is disposed below the second black matrix S052. In one embodiment, the second black matrix S052 shields the data line S09 and the electric field shielding electrode S11 along a direction (axial direction Z), as shown in Figure 3D. The second black matrix S052 blocks the scan line S10 and the electric field shielding electrode S11 along the axial Z direction, as shown in Figure 3E. In other words, the second black matrix S052 completely blocks the scan line S10, the data line S09, and the electric field shielding electrode S11 along this direction.
[0040] The array substrate pixel in Figure 3A is formed by sputtering a first metal layer M1 (any conductive metal material such as molybdenum-aluminum alloy, copper, or copper alloy) onto the substrate, and then forming scan lines S10, the gate of the TFT (SW), and electric field shielding electrodes S11 through a first photolithography and etching process. This includes two main parts: parallel scan lines S10 and data lines S09. Next, a gate insulating layer (such as SiNx) / a-Si / n+ layers (GIN) are deposited by CVD process. An island-shaped GIN pattern is formed by a second photolithography and etching process. The area outside the island-shaped GIN pattern is then selectively etched to remove a-Si / n+, leaving only the gate insulating layer. Then, a second metal layer M2 (any conductive metal material such as molybdenum-aluminum alloy, copper, or copper alloy) is sputtered, and then the source and drain of the TFT and data lines S09 are formed by a third photolithography and etching process. By removing n+ and part of the a-Si layer through an n+ etching process, a thin film transistor channel (TFT) can be formed. The process involves: first, depositing a Pas layer (passivation layer, such as silicon nitride) using CVD to protect the TFT channel; then, coating the lower substrate with a photosensitive organic resin layer (OG layer) followed by a fourth photolithography process to form a flattening layer and via holes; next, a fifth photolithography process followed by etching of the Pas layer and gate insulating layer to generate via holes connecting the drain to the pixel electrode S07 and surrounding metal signal lines; finally, sputtering a first transparent conductive layer ITO1 (such as ITO, IZO, etc.) followed by a sixth photolithography and etching process to form the pixel electrode S07. This is the fabrication process for a six-mask array substrate. In other embodiments, the OG layer can be omitted, reducing the number of masks on the array substrate and production costs, while also reducing light transmittance loss when passing through the OG layer.
[0041] Compared to the structure in Figure 2A, the structure in Figure 3A reduces one photomask and the electric field shielding electrode S11 is entirely converted to reflect the contribution of incident light. The electrical connection can be floating or connected to the Com signal. In addition, drilling holes in the shielding electrode can reduce the parasitic capacitance between the data line S09 and the electric field shielding electrode S11 and reduce electrostatic discharge damage during the fabrication process; the area of the pixel electrode S07 projected onto the electric field shielding electrode S11 can be used as a storage capacitor.
[0042] The combination of the array pixels in Figure 3A and the second black matrix S052 pattern in Figure 3B can obtain the pixel combination in Figure 3C. The cross-section AA of the data line S09 position of the pixel is shown in Figure 3D; the cross-section BB of the scan line S10 position of the pixel is shown in Figure 3E. In the array substrates of Figures 3C, 3D and 3E, incident light can only enter and exit through the edge of the second black matrix S052 pattern. Although this avoids glare caused by the reflection of ambient light by the data line S09, it also reduces the aperture ratio of the pixel. The distance between the second black matrix S052 on the upper plate and the edge of the metal line on the lower plate is greater than or equal to (≥) 3 micrometers. The width of the overlapping portion of the pixel electrode S07 and the electric field shielding electrode S11 on the lower plate is greater than or equal to (≥) 1.5 micrometers. The distance between the edges of the overlapping area of the data line S09 and part of the electric field shielding electrode S11 is greater than or equal to (≥) 1.5 micrometers. Furthermore, the second black matrix S052, pixel electrode S07, data line S09, and electric field shielding electrode S11 are stacked along this direction (axial direction Z) to form a light-transmitting aperture LH. The light-transmitting aperture LH has a first light-transmitting aperture diameter D1 along a first radial direction (axial direction X), and a second light-transmitting aperture diameter D2 along a second radial direction (axial direction Y). The first radial direction is perpendicular to the second radial direction, and both the first and second radial directions are perpendicular to this direction. Both the first light-transmitting aperture diameter D1 and the second light-transmitting aperture diameter D2 are determined by the second black matrix S052.
[0043] Please refer to Figures 4A, 4B, 4C, 4D, and 4E together, wherein Figure 4B is a schematic diagram illustrating the third black matrix S053 of the present invention; Figure 4C is a schematic diagram illustrating the third pixel module of the display device of the present invention combined with the third black matrix S053; Figure 4D is a cross-sectional view along line AA in Figure 4C; and Figure 4E is a cross-sectional view along line BB in Figure 4C. One of the third pixel units 3a2 of the display panel of the display device includes a third pixel module and a third black matrix S053. The third black matrix S053 is disposed above the scan line S10, the data line S09, the pixel electrode S07, and the electric field shielding electrode S11, that is, the pixel electrode S07 is disposed below the third black matrix S053. In one embodiment, the third black matrix S053 shields the data line S09 and the electric field shielding electrode S11 along a direction (axial direction Z), as shown in Figure 4D. The third black matrix S053 blocks the scan line S10 and the electric field shielding electrode S11 along the axial Z direction, as shown in Figure 4E. In other words, the third black matrix S053 completely blocks the scan line S10, the data line S09, and the electric field shielding electrode S11 along this direction.
[0044] The array substrate pixel in Figure 4A is formed by sputtering a first transparent conductive layer ITO1 (such as ITO, IZO, etc.) and a first metal layer M1 (any conductive metal material such as molybdenum-aluminum alloy, copper, or copper alloy) on the substrate. The first exposure and first etching process are performed by a half-tone mask to form the scan line S10, the gate of the TFT (SW), and the electric field shielding electrode S11. The photoresist above the corresponding position of the data line S09 is ablated, and then the upper first metal layer M1 is removed by a second etching. Thus, the structure is obtained where the upper layer of the part parallel to the scan line S10 is metal M1 and the part parallel to the data line S09 is transparent ITO1. Then, the gate insulating layer (such as SiNx) / a-Si / n+ is deposited by CVD process. The process involves a second photolithography and etching process to form an island-shaped GIN pattern. The area outside the island GIN pattern is then selectively etched to remove the a-Si / n+ layer, leaving only the gate insulating layer. Next, a second metal layer M2 (any conductive metal such as molybdenum-aluminum alloy, copper, or copper alloy) is sputtered. A third photolithography and etching process then forms the source and drain of the TFT and the data line S09. Finally, an n+ etching process removes the n+ layer and part of the a-Si layer, thus forming the thin-film transistor channel (TFT). The process involves: first, depositing a Pas layer (passivation layer, such as silicon nitride) using CVD to protect the TFT channel; then, coating the lower substrate with a photosensitive organic resin layer (OG layer) followed by a fourth photolithography process to form a flattening layer and via holes; next, a fifth photolithography process followed by etching of the Pas layer and gate insulating layer to generate via holes connecting the drain to the pixel electrode S07 and surrounding metal signal lines; finally, sputtering a second transparent conductive layer ITO2 (such as ITO, IZO, etc.) followed by a sixth photolithography and etching process to form the pixel electrode S07. This is the fabrication process for a six-mask array substrate. In other embodiments, the OG layer can be omitted, reducing the number of masks on the array substrate and production costs, while also reducing light transmittance loss when passing through the OG layer. In addition, the patterns of the first transparent conductive layer ITO1 (such as ITO, IZO, etc.) and the first metal layer M1 can also be formed by two photomasks respectively. The electric field shielding electrode S11 is formed by the photomask of the first transparent conductive layer ITO1, and the partial electric field shielding electrode S11 and the scan line S10 are formed by the photomask of the first metal layer M1.
[0045] Compared to the structure in Figure 2A, the structure in Figure 4A utilizes a half-tone mask, which reduces the number of photomasks. The electric field shielding electrode S11 simultaneously contributes to increasing the aperture and reflecting incident light, and can be floating or connected to the Com signal electrically. In addition, drilling holes in the electric field shielding electrode S11 can reduce the parasitic capacitance between the data line S09 and the electric field shielding electrode S11 and reduce electrostatic discharge damage during fabrication. The area of the pixel electrode S07 projected onto the electric field shielding electrode S11 can be used as a storage capacitor.
[0046] The combination of the array pixels in Figure 4A and the third black matrix S053 pattern in Figure 4B yields the pixel combination in Figure 4C. The cross-section AA of the pixel data line S09 is shown in Figure 4D; the cross-section BB of the pixel scan line S10 is shown in Figure 4E. In the array substrates of Figures 4C, 4D, and 4E, incident light can only enter and exit through the edge of the third black matrix S053 pattern. While this avoids glare caused by the reflection of ambient light by the data line S09, it also reduces the pixel aperture ratio. The distance between the upper plate third black matrix S053 and the edge of the lower plate metal line is greater than or equal to (≥) 3 micrometers. The width of the overlapping portion of the pixel electrode S07 and the electric field shielding electrode S11 on the lower plate is greater than or equal to (≥) 1.5 micrometers. The distance between the edges of the overlapping area of the data line S09 and part of the electric field shielding electrode S11 is greater than or equal to (≥) 1.5 micrometers. Furthermore, the third black matrix S053, pixel electrode S07, data line S09, and electric field shielding electrode S11 are stacked along this direction (axial direction Z) to form a light-transmitting aperture LH. The light-transmitting aperture LH has a first light-transmitting aperture diameter D1 along a first radial direction (axial direction X), and a second light-transmitting aperture diameter D2 along a second radial direction (axial direction Y). The first radial direction is perpendicular to the second radial direction, and both the first and second radial directions are perpendicular to this direction. Both the first light-transmitting aperture diameter D1 and the second light-transmitting aperture diameter D2 are determined by the third black matrix S053.
[0047] The various array TFT substrates described above are illustrated using amorphous silicon semiconductors as examples. If IGZO is used as the semiconductor material, SiO2 can be added above the original gate insulating layer (SiNx), and in addition to SiNx, SiO2 can also be added to the passivation layer, forming a structure with upper and lower semiconductor layers to ensure the electrical stability of the oxide semiconductor. Furthermore, the TFT of this invention is described using a bottom-gate process, but top-gate TFTs can also be applied to this invention. This invention is not limited to the above.
[0048] Please refer to Figures 2D, 3D, 4D, and 5 together, wherein Figure 5 is a schematic diagram illustrating various relative projection relationships between the punch-hole type electric field shielding electrode S11 and the data line S09 of the present invention. When a punch-hole type electric field shielding electrode S11 is used, the projection of the punched-out portion of the electric field shielding electrode S11 and the data line S09 can form three relationships: overlap, alignment, single-sided overlap, and no overlap. This can reduce the parasitic capacitance between the data line S09 and the electric field shielding electrode S11 to varying degrees, making it more suitable for applications of large-size display panels. The punch-hole type electric field shielding electrode S11 includes a first shielding electrode portion S112 and a second shielding electrode portion S114, with a hole HL formed between the first shielding electrode portion S112 and the second shielding electrode portion S114, and the hole HL is located below the data line S09.
[0049] Please refer to Figures 2A to 2E, 3A to 3E, 4A to 4E, 6A, 6B, 6C, and 6D together. Figure 6A is a cross-sectional view of the plurality of display panels of the full-color display device 100 of the present invention along line AA, which contains an OG layer S13 and the electric field shielding electrode S11 is not perforated; Figure 6B is a cross-sectional view of the plurality of display panels of the full-color display device 100 of the present invention along line AA.

In Figures 6A and 6B, the full-color display device 100 includes a plurality of display panels, including a first display panel 110, a second display panel 120, and a third display panel 130. The first display panel 110 displays a first color; the second display panel 120 displays a second color; and the third display panel 130 displays a third color. The first display panel 110, the second display panel 120, and the third display panel 130 are stacked sequentially, with the first color, the second color, and the third color being different from each other. In Figures 6C and 6D, the full-color display device 100a includes a plurality of display panels, including a first display panel 110a, a second display panel 120a, and a third display panel 130a. The difference between the full-color display device 100 and the full-color display device 100a is that the electric field shielding electrode S11 of the full-color display device 100 does not have a hole, while the electric field shielding electrode S11 of the full-color display device 100a has a hole.
[0050] Specifically, any one of the first display panels 110, 110a, the second display panels 120, 120a, and the third display panels 130, 130a is a cholesteric liquid crystal panel, with the first color being blue (B), the second color being green (G), and the third color being red (R), respectively. In other words, the full-color display device 100 and the full-color display device 100a are, from top to bottom, three display panels of blue, green, and red, and are attached to each other with optically clear adhesive (OCA). The bottom layer is a light-absorbing plate S14. Each display panel includes an upper substrate S01, an overcoat (OC layer) S02, an electrode S03, a frame adhesive S04, a black matrix S05, a cholesteric liquid crystal S06, a pixel electrode S07, an insulating layer S08, a data line S09, a scan line S10, an electric field shielding electrode S11, a lower substrate S12, and an organic layer (OG layer) S13. Electrode S03 is the upper substrate Com electrode. The frame adhesive S04 contains anisotropic conductive gold balls. The black matrix S05 completely shields the data line S09 and the electric field shielding electrode S11. The insulating layer S08 consists of a gate insulating layer GI and a passivation layer PAS. The electric field shielding electrode S11 can be a through-type (transparent conductive material), a reflective type (metallic conductive material), or a semi-through / semi-reflective type (achieved by stacking a transparent conductive material layer with a metallic conductive material layer using a half-tone mask for one-time patterning or two photolithography and etching processes). The upper substrate S01 and the lower substrate S12 are not limited to glass, but can also be flexible substrates such as plastics. The organic layer (OG layer) S13 is disposed between the pixel electrode S07 and the data line S09, and is connected to the pixel electrode S07.
[0051] Please refer to Figures 2A to 2E, 3A to 3E, 4A to 4E, 6A to 6D, 7A, 7B, 7C, and 7D, wherein Figure 7A is a cross-sectional view of the plurality of display panels of the full-color display device of the present invention along line AA, which has no OG layer S13 and the electric field shielding electrode S11 is not perforated; Figure 7B is a view of the full-color display device of the present invention... Figure 7A and Figure 7B show cross-sectional views of multiple display panels along line BB, without an OG layer S13 and without holes for the electric field shielding electrode S11; Figure 7C shows a cross-sectional view of multiple display panels of the full-color display device of the present invention along line AA, without an OG layer S13 and with holes for the electric field shielding electrode S11; and Figure 7D shows a cross-sectional view of multiple display panels of the full-color display device of the present invention along line BB, without an OG layer S13 and with holes for the electric field shielding electrode S11. In Figures 7A and 7B, the full-color display device 100b includes a plurality of display panels, including a first display panel 110b, a second display panel 120b, and a third display panel 130b. The first display panel 110b displays a first color; the second display panel 120b displays a second color; and the third display panel 130b displays a third color. The first display panel 110b, the second display panel 120b, and the third display panel 130b are stacked sequentially, with the first color, the second color, and the third color being different from each other. In Figures 7C and 7D, the full-color display device 100c includes a plurality of display panels, including a first display panel 110c, a second display panel 120c, and a third display panel 130c. The difference between the full-color display device 100b and the full-color display device 100c is that the electric field shielding electrode S11 of the full-color display device 100b does not have a hole, while the electric field shielding electrode S11 of the full-color display device 100c has a hole.
[0052] Specifically, any one of the first display panels 110b and 110c, the second display panels 120b and 120c, and the third display panels 130b and 130c is a cholesteric liquid crystal panel, with the first color, second color, and third color being blue (B), green (G), and red (R), respectively. In other words, the full-color display device 100b and the full-color display device 100c are, from top to bottom, three display panels: blue, green, and red, which are attached to each other using OCA. The bottom layer is a light-absorbing plate S14. Each display panel includes an upper substrate S01, a protective layer (overcoat; OC layer) S02, an electrode S03, a frame adhesive S04, a black matrix S05, cholesteric liquid crystal S06, a pixel electrode S07, an insulating layer S08, a data line S09, a scan line S10, an electric field shielding electrode S11, and a lower substrate S12. The difference between Figures 7A to 7D and Figures 6A to 6D is that the structures in Figures 7A to 7D do not have an OG layer S13, that is, no OG layer S13 is added to the array substrate below it. This can reduce the number of photomasks and production costs of the array substrate, and also reduce the transmittance loss when light passes through the OG layer S13.
[0053] Please refer to Figures 2A, 2C, 3A, 3C, 4A, 4C, and 8, where Figure 8 is a tree diagram illustrating the various electric field shielding electrodes S11 combinations of multiple display panels in the full-color display device of the present invention. To more systematically illustrate how to improve the aperture ratio, the present invention encodes embodiments of the full-color display device (full-color active-matrix liquid crystal display module), which includes a first code, a second code, a third code, and a fourth code. The first code represents the type of display module embodiment; the first code is "A," where the upper plate of each of the three monochrome display panels has a black matrix S05 that completely shields the data lines S09 and the electric field shielding electrodes S11, as shown in Figures 2C, 3C, and 4C. The second code represents the type of electric field shielding electrode S11 for the blue display panel. The third code represents the type of electric field shielding electrode S11 for the green display panel. The fourth code represents the type of electric field shielding electrode S11 of the red display panel. The second, third, and fourth codes are any one of the numbers 1, 2, and 3, representing the type of electric field shielding electrode S11. This invention divides the electric field shielding electrodes S11 into three main categories, with the coding rules as follows: "1" represents transmissive (transparent conductive material), abbreviated as TR; "2" represents reflective (metallic conductive material), abbreviated as RE; and "3" represents semi-transmissive and semi-reflective (the patterned part of the electrode is translucent and partially reflects incident ambient light), abbreviated as TF. In the tree diagram of Figure 8, all structures corresponding to the codes include both OG layer S13 and array substrates without OG layer S13.
[0054] In the three embodiments of monochrome display panels, the lower plate can be implemented by selecting one of the array substrates in Figures 2A, 3A and 4A, for example: encoding A.1.1.1, A.2.2.2, A.3.3.3.
[0055] In the three embodiments of monochrome display panels, the lower plate can be implemented by selecting any two of the array substrates in Figures 2A, 3A and 4A, for example: codes A.1.1.2, A.1.1.3, A.1.2.1, A.1.2.2, A.1.3.1, A.1.3.3, A.2.1.1, A.2.1.2, A.2.2.1, A.2.2.3, A.2.3.2, A.2.3.3, A.3.1.1, A.3.1.3, A.3.2.2, A.3.2.3, A.3.3.1, A.3.3.2.
[0056] In the embodiment of the three monochrome display panels, the lower plate can be implemented by selecting three non-repeating pixel modules from the array substrates of Figures 2A, 3A and 4A, for example: encoding A.1.2.3, A.1.3.2, A.2.1.3, A.2.3.1, A.3.1.2, A.3.2.1.
[0057] In the embodiment of encoding A.1.1.1, the electric field shielding electrodes S11 are all light-transmitting. Because shielding the electric field influence of the data line S09 on the pixel electrode S07 can minimize the width of the edge of the BM shielding pixel electrode S07, only the alignment tolerance accuracy of the upper and lower substrates during the cell assembly process (BM to metal edge distance ≥ 3 micrometers) needs to be considered, and the reflection of the metal line can be avoided without considering liquid crystal leakage, thereby improving the aperture ratio and contrast.
[0058] In the embodiment of encoding A.2.2.2, the electric field shielding electrodes S11 are all opaque. Because shielding the electric field influence of the data line S09 on the pixel electrode S07 can minimize the width of the edge of the BM shielding pixel electrode S07, only the alignment tolerance accuracy of the upper and lower substrates during the cell assembly process (BM to metal edge distance ≥ 3 micrometers) needs to be considered, and the reflection of the metal line can be avoided without considering liquid crystal leakage, thereby improving the aperture ratio and contrast.
[0059] In the embodiment of code A.3.3.3, the electric field shielding electrode S11 is partially transparent. Because shielding the electric field influence of the data line S09 on the pixel electrode S07 can minimize the width of the edge of the BM shielding pixel electrode S07, only the alignment tolerance accuracy of the upper and lower substrates during the cell assembly process (BM to metal edge distance ≥ 3 micrometers) needs to be considered, and the reflection of the metal line can be avoided without considering liquid crystal leakage. This can improve the aperture ratio and contrast.
[0060] The process flow of the three array substrates in Figures 2A, 3A and 4A differs only in the manufacturing process of the scan line S10 and the electric field shielding electrode S11. The subsequent processes from the GIN layer to the photomask formed by the pixel electrode S07 are the same, and they still have great production compatibility.
[0061] The embodiments of codes A.1.1.1, A.2.2.2, and A.3.3.3 are each composed of a single array substrate and each is paired with a different liquid crystal cell thickness, wherein: R > G > B.
[0062] The embodiments other than those coded A.1.1.1, A.2.2.2, and A.3.3.3 have different array substrates and are subject to greater limitations in the production process, but they are still feasible to implement under the requirement of improving aperture ratio and contrast.
[0063] In summary, the light aperture of the data line S09 and the electric field shielding electrode S11 on each monochrome display panel is limited by the upper plate BM. However, under the action of the electric field shielding electrode S11, the width of the edge of the pixel electrode S07 shielded by the BM can be minimized. In addition, when forming a full-color active cholesteric liquid crystal display module, the alignment accuracy between monochrome screens is about 5 to 15 micrometers, which causes the BM to lose the aperture ratio again. Furthermore, since the BM completely shields the reflected light of the metal lines, there is almost no incident light recycling efficiency. However, due to the absence of pixel light leakage and glare caused by the absence of metal lines reflecting incident light, a better aperture ratio and contrast ratio can still be obtained.
[0064] To facilitate comparison of the light aperture and the light path for the recycling of incident light, in all the following embodiments, different cholesteric liquid crystal display panel pixels are arranged side by side in the same liquid crystal cell; in fact, the same pixel structure is used in the same color display panel. Furthermore, in the following top view and sectional view, pixel structures with different codes are arranged side by side in the same drawing to facilitate comparison of similarities and differences; in fact, the top view shows the topmost (blue) pixel structure of the same code, and the sectional view shows the structure of the same code.

The electric field shielding electrodes S11 of the blue and green display panels (BG) are both light-transmitting, while in the red display panel (R), only codes A.1.1.1 and A.1.1.3 are light-transmitting, while code A.1.1.2 is an opaque metal layer.
[0068] In Figures 9J and 9L, the full-color display device, from top to bottom, consists of pixel cross-sectional views of blue, green, and red display panels at the scan line S10 position and the bottom light-absorbing plate S14. In the three embodiments, the electric field shielding electrodes S11 of the blue and green display panels (BG) are all light-transmitting, while only code A.1.1.1 in the red display panel (R) is light-transmitting, while codes A.1.1.2 and A.1.1.3 are opaque metal layers.
[0069] Accordingly, the structures of the first code A.1.1.1, the second code A.1.1.2 and the third code A.1.1.3 of the present invention all shield the electric field influence of the data line S09 on the pixel electrode S07, thereby minimizing the BM shading width and thus improving the aperture ratio and contrast.

The blue display panel (B) in the three embodiments has the same pixel structure, the green display panel (G) has the same pixel structure, while the array substrate in the red display panel (R) is different for each embodiment.
[0107] In Figures 17B, 17D, 17F, and 17H, the full-color display device, from top to bottom, consists of pixel cross-sectional views of blue, green, and red display panels at the data line S09 position and the bottom light-absorbing plate S14. In all three embodiments, the electric field shielding electrodes S11 are located below the data line S09.

[0109] Accordingly, the structures of the 25th code A.3.2.1, the 26th code A.3.2.2 and the 27th code A.3.2.3 of the present invention all shield the electric field influence of the data line S09 on the pixel electrode S07, thereby minimizing the BM shading width and thus improving the aperture ratio and contrast.
[0110] As can be seen from the above embodiments, the present invention has the following advantages: First, by using an electric field shielding electrode to reduce the electric field between the data line and the pixel electrode, the light leakage range of the cholesteric liquid crystal is reduced, thereby reducing the BM shielding width. Furthermore, by reducing the BM shielding range and then exposing the data line and electric field shielding electrode, the light-transmitting aperture is determined by the width of the data line or the electric field shielding electrode, allowing the surface of the metal line in the monochrome display to reflect incident light and improve the light recycling efficiency. The light-transmitting electric field shielding electrode can further improve the light-transmitting aperture of the pixel. Second, during the process of aligning and bonding the BGR display panels to form a module, the reduction in the BM shielding range again significantly reduces the aperture ratio loss related to BM shielding caused by alignment accuracy during three-panel bonding. Through the above technical means, an active array cholesteric liquid crystal display module with high aperture ratio and high contrast can be achieved, thereby solving the problems of excessively small aperture ratio and low contrast in the prior art.
