Description

Technical Field

[0001] This invention relates to a display panel, and more particularly to a reflective display panel. Background Technology

[0002] Liquid crystal display (LCD) panels can generally be divided into three main categories: transmissive, reflective, and transflective-reflective. The classification is based on the differences in the lighting source and the configuration of the pixel array substrate. Reflective LCD panels primarily utilize natural or ambient light as their light source. Because they do not require backlighting, they possess excellent energy-saving characteristics. Therefore, they are commonly used outdoors or in well-lit environments, such as billboards, electronic tags, sports watches, or e-readers.

[0003] To meet the demands of color display, reflective liquid crystal display panels can incorporate color filter layers to achieve the desired display colors. Generally, a color filter layer can include multiple filter patterns of different colors, and the distribution area of ​​these filter patterns is roughly the same. Since the human eye's sensitivity to different colors of light varies, if the aforementioned multiple filter patterns are set with the same distribution area, the displayed image will easily appear distorted or have color shift. Summary of the Invention

[0004] This invention relates to a reflective display panel with superior visual quality for color display.

[0005] According to an embodiment of the present invention, a reflective display panel includes a first substrate, a second substrate, a first pixel structure, a second pixel structure, a color filter layer, and a display medium layer. The first substrate and the second substrate are disposed opposite to each other, and the display medium layer is disposed between the first substrate and the second substrate. The first pixel structure and the second pixel structure are disposed on the first substrate and respectively have a first reflective electrode and a second reflective electrode. The color filter layer is disposed on the second substrate and is disposed corresponding to the first reflective electrode and the second reflective electrode. The color filter layer includes a first filter pattern projected and superimposed on the first reflective electrode and a second filter pattern projected and superimposed on the second reflective electrode. The filter colors of the first filter pattern and the second filter pattern are different from each other. The percentage value of the positively projected area of ​​the first filter pattern on the reflective surface of the first reflective electrode to the area of ​​the reflective surface of the first reflective electrode is greater than the percentage value of the positively projected area of ​​the second filter pattern on the reflective surface of the second reflective electrode to the area of ​​the reflective surface of the second reflective electrode.

[0006] In a reflective display panel according to an embodiment of the present invention, a first filter pattern and a second filter pattern are respectively provided with a first opening and a second opening, and the projected area of ​​the first opening on the reflective surface of the first reflective electrode is smaller than the projected area of ​​the second opening on the reflective surface of the second reflective electrode.

[0007] In a reflective display panel according to an embodiment of the present invention, the filter color of the first filter pattern is red or blue, and the filter color of the second filter pattern is green.

[0008] In a reflective display panel according to an embodiment of the present invention, the first opening and the second opening are not connected to each other.

[0009] In a reflective display panel according to an embodiment of the present invention, a first filter pattern and a second filter pattern are respectively provided with a first opening and a second opening, and the first opening and the second opening are connected.

[0010] In a reflective display panel according to an embodiment of the present invention, the orthographic projection profile of the first opening on the reflective surface of the first reflective electrode is different from the orthographic projection profile of the second opening on the reflective surface of the second reflective electrode.

[0011] In a reflective display panel according to an embodiment of the present invention, the reflective display panel further includes a third pixel structure. The third pixel structure is disposed on a first substrate and has a third reflective electrode. The color filter layer further includes a third filter pattern superimposed on the third reflective electrode. The third filter pattern has a third opening. The first opening, the second opening, and the third opening are interconnected, and the projected area of ​​the third opening on the reflective surface of the third reflective electrode is smaller than the projected area of ​​the second opening on the reflective surface of the second reflective electrode.

[0012] In a reflective display panel according to an embodiment of the present invention, the overall orthographic projection outline of the first opening, the second opening and the third opening on the first substrate includes a rhombus shape.

[0013] In a reflective display panel according to an embodiment of the present invention, the material of the display medium layer includes liquid crystal.

[0014] In a reflective display panel according to an embodiment of the present invention, the first opening and the second opening are each filled with a transparent pattern suitable for allowing white light to pass through.

[0015] Based on the above, in a reflective display panel according to an embodiment of the present invention, the color filter layer has two filter patterns overlapping different pixel structures and having different filter colors. The orthographic projection ratios of these two filter patterns on the reflective surfaces of their respective reflective electrodes are not the same, thus optimizing the visual quality of the reflective display panel when displaying colors.

[0048] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0049] The foregoing descriptions and other technical contents, features, and effects of this invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0050] Figure 1 This is a cross-sectional schematic diagram of a reflective display panel according to a first embodiment of the present invention. Figure 2 yes Figure 1 A top-view schematic diagram of a portion of the film layer of a reflective display panel. Please refer to... Figure 1 and Figure 2 The reflective display panel 10 includes a first substrate 100 and a plurality of pixel structures PX. Although Figure 1 Only one pixel structure PX is shown, but it will be understood that multiple pixel structures PX can be arranged in an array on the first substrate 100. For example, these pixel structures PX can be arranged in multiple rows and columns along two mutually perpendicular directions (e.g., direction X and direction Y). The material of the first substrate 100 may include glass, quartz, polymer (e.g., polyimide, polycarbonate, polymethyl methacrylate, or other suitable flexible substrate), or other suitable substrate.

[0051] In this embodiment, the pixel structure PX may include an active element T and a reflective electrode RE electrically connected to each other. For example, a method of forming the active element T may include the following steps: sequentially forming a gate GE, a gate insulating layer 110, a semiconductor pattern SC, a source SE, and a drain DE on a first substrate 100. The semiconductor pattern SC overlaps the gate GE. The source SE and drain DE overlap the semiconductor pattern SC and are electrically contacted with two different regions of the semiconductor pattern SC. In this embodiment, the gate GE of the active element T may optionally be disposed below the semiconductor pattern SC to form a bottom-gate thin-film transistor (TFT), but this is not a limitation. In other embodiments, the gate of the active element may also optionally be disposed above the semiconductor pattern to form a top-gate thin-film transistor (TFT).

[0052] It should be noted that the gate GE, source SE, drain DE, semiconductor pattern SC, and gate insulating layer 110 can be implemented by any gate, source, drain, semiconductor pattern, and gate insulating layer known to those skilled in the art for use in reflective display panels. Furthermore, the gate GE, source SE, drain DE, semiconductor pattern SC, and gate insulating layer 110 can be formed by any method known to those skilled in the art, and therefore will not be elaborated upon here.

[0053] Furthermore, the reflective display panel 10 may also include a passivation layer 120 and a planarization layer 130. The passivation layer 120 covers multiple active elements T of the multiple pixel structure PX. The planarization layer 130 covers the passivation layer 120. In this embodiment, the material of the planarization layer 130 may be an organic material, and the material of the passivation layer 120 may be an inorganic material. The passivation layer 120 is located between the planarization layer 130 and the metal electrodes (e.g., source SE and drain DE) of the active elements T to avoid poor adhesion between the planarization layer 130 and the metal electrodes, thus preventing them from peeling off from each other, but this is not a limitation.

[0054] The reflective electrode RE of the pixel structure PX is disposed on the surface 130s of the planarization layer 130 facing away from the first substrate 100, and is electrically connected to the drain DE of the active element T via the opening OP of the planarization layer 130 and the contact hole TH of the passivation layer 120. The distribution range of the reflective electrode RE defines the reflective region RA of the pixel structure PX. The material of the reflective electrode RE includes, for example, metals (e.g., silver), alloys, nitrides of metal materials, oxides of metal materials, oxynitrides of metal materials, or other suitable materials, or a stacked layer of metal materials and other conductive materials, but is not limited thereto. For example, in this embodiment, a transparent conductive layer (not shown) may also be disposed below the reflective electrode RE to interface with the drain DE, and this transparent conductive layer can improve the poor adhesion that may occur when the reflective electrode RE is directly fabricated on the planarization layer 130.

[0055] In this embodiment, the reflective display panel 10 may further include a second substrate 200 and a display medium layer 300. The display medium layer 300 is disposed between the first substrate 100 and the second substrate 200. The material of the display medium layer 300 includes liquid crystal, that is, the display medium layer 300 may be a liquid crystal layer. More specifically, the reflective display panel 10 of this embodiment may be a reflective liquid crystal display panel, but is not limited thereto.

[0056] To achieve a color display effect, the reflective display panel 10 may further include a color filter layer CFL disposed on the reflective surface RS side of the reflective electrode RE. In this embodiment, the color filter layer CFL may be disposed on the second substrate 200, but is not limited thereto. For example, in this embodiment, the plurality of pixel structures PX may be divided into a plurality of pixel structures PX1, a plurality of pixel structures PX2, and a plurality of pixel structures PX3, and a pixel structure PX1, a pixel structure PX2, and a pixel structure PX3 arranged adjacently may constitute a display unit of the reflective display panel 10. In other words, pixel structure PX1, pixel structure PX2, and pixel structure PX3 may each be a display sub-pixel of a display unit, but is not limited thereto.

[0057] Correspondingly, the color filter layer CFL may include multiple filter patterns FP1, multiple filter patterns FP2, and multiple filter patterns FP3. The filter colors of filter patterns FP1, FP2, and FP3 are different from each other. In the normal direction (e.g., direction Z) of the reflective surface RS, multiple filter patterns FP1 are projected and superimposed on multiple reflective electrodes RE1 of multiple pixel structures PX1, multiple filter patterns FP2 are projected and superimposed on multiple reflective electrodes RE2 of multiple pixel structures PX2, and multiple filter patterns FP3 are projected and superimposed on multiple reflective electrodes RE3 of multiple pixel structures PX3.

[0058] In this embodiment, the areas of the reflective surfaces RS of the reflective electrodes RE1 of pixel structure PX1, RE2 of pixel structure PX2, and RE3 of pixel structure PX3 are all approximately the same. It is particularly noteworthy that the percentage of the area of ​​the orthographic projection of the filter pattern FP1 onto the reflective surface RS of reflective electrode RE1 is greater than the percentage of the area of ​​the orthographic projection of the filter pattern FP2 onto the reflective surface RS of reflective electrode RE2.

[0059] From another perspective, filter patterns FP1 and FP2 are respectively provided with openings OP1 and OP2, and the orthographic projection area of ​​opening OP1 of filter pattern FP1 on the reflective surface RS of reflective electrode RE1 is smaller than the orthographic projection area of ​​opening OP2 of filter pattern FP2 on the reflective surface RS of reflective electrode RE2. In this embodiment, openings OP1 of filter pattern FP1 and OP2 of filter pattern FP2 are not connected to each other, but this is not a limitation. It is particularly noteworthy that in this embodiment, filter pattern FP3 is not provided with an opening, but this is not a limitation.

[0060] Since the human eye has different sensitivities to different colors of light, by adjusting the ratio of the positive projection area of ​​the filter patterns FP1 and FP2 of different filter colors (such as red and green, or blue and green) on the reflective surface RS of the corresponding reflective electrode RE to the area of ​​the reflective surface RS, the color quality perceived by the human eye when the reflective display panel 10 is performing color display can be optimized.

[0061] For example, in this embodiment, the filter colors of filter patterns FP1 and FP3 can be red and blue, respectively, while the filter color of filter pattern FP2 can be green, but is not limited thereto. The human eye is significantly more sensitive to green light than to red and blue light. Therefore, by making the ratio of the projected area of ​​filter pattern FP1 on the reflective surface RS of reflective electrode RE1 to the area of ​​reflective surface RS, and the ratio of the projected area of ​​filter pattern FP3 on the reflective surface RS of reflective electrode RE3 to the area of ​​reflective surface RS, to the ratio of the projected area of ​​filter pattern FP2 on the reflective surface RS of reflective electrode RE2, the proportion of red or blue light in the overall display light can be increased or the proportion of green light in the overall display light can be decreased, thereby improving the color distortion or color shift problems experienced by the human eye when viewing displayed images.

[0062] In this embodiment, the orthographic projection outlines of the opening OP1 of filter pattern FP1 and the opening OP2 of filter pattern FP2 on the reflective surface RS of the reflective electrode RE are, for example, rhombuses, but are not limited thereto. In other embodiments, the orthographic projection outlines of the openings of the filter patterns on the reflective surface RS can be triangles, circles, ellipses, rectangles, polygons, or combinations thereof. In this embodiment, the openings OP1 of filter pattern FP1 and OP2 of filter pattern FP2 can be filled with transparent patterns TP1 and TP2, respectively, suitable for allowing white light to pass through, but are not limited thereto.

[0063] Furthermore, a common electrode layer (not shown) may be provided on the second substrate 200, and the color filter layer CFL is located between the common electrode layer and the second substrate 200. The electric field generated between the common electrode layer and the reflective electrode RE is suitable for driving multiple liquid crystal molecules (not shown) of the liquid crystal layer (i.e., the display medium layer 300) to rotate and form an arrangement state corresponding to the direction and intensity of the electric field. By changing the arrangement state of these liquid crystal molecules, the polarization state of the light passing through the liquid crystal layer is changed, thereby forming a light output brightness corresponding to the arrangement state. However, the present invention is not limited thereto. In other embodiments, the common electrode layer may be provided on the first substrate 100.

[0064] Another embodiment will be described below to illustrate this disclosure in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted. For the omitted parts, please refer to the foregoing embodiments, and they will not be repeated below.

[0065] Figure 3 This is a top view schematic diagram of a reflective display panel according to a second embodiment of the present invention. Please refer to... Figure 3 The reflective display panel 10A in this embodiment and Figure 2 The only difference between the reflective display panel 10 and the previous one is the opening arrangement of the color filter layer. Specifically, in the color filter layer CFL-A of this embodiment, the opening OP1a of the filter pattern FP1a is connected to the opening OP2a of the filter pattern FP2a, and the orthographic projection outline of the opening OP1a of the filter pattern FP1a on the reflective surface of the reflective electrode RE1 is different from the orthographic projection outline of the opening OP2a of the filter pattern FP2a on the reflective surface of the reflective electrode RE2.

[0066] For example, in this embodiment, the orthographic projection outline of the opening OP1a of the filter pattern FP1a on the reflective electrode RE1 can be a triangle, while the orthographic projection outline of the opening OP2a of the filter pattern FP2a on the reflective electrode RE2 can be a rectangle. Therefore, in this embodiment, the transparent pattern TPa, which fills the openings OP1a and OP2a of the connected filter patterns FP1a and FP2a, has a pentagonal top view outline along the Z direction.

[0067] Figure 4 This is a top view schematic diagram of a reflective display panel according to a third embodiment of the present invention. Please refer to... Figure 4 The reflective display panel 10B in this embodiment and Figure 2 The only difference between the reflective display panel 10 and the other is the opening arrangement of the color filter layer. Specifically, in the color filter layer CFL-B of this embodiment, in addition to the filter patterns FP1b and FP2b having openings OP1b and OP2b respectively, the filter pattern FP3b overlapping the reflective electrode RE3 of the pixel structure PX3 also has an opening OP3b.

[0068] In this embodiment, the opening OP1b of the filter pattern FP1b, the opening OP2b of the filter pattern FP2b, and the opening OP3b of the filter pattern FP3b are connected. The orthographic projection profile of the opening OP1b of the filter pattern FP1b on the reflective surface of the reflective electrode RE1 and the orthographic projection profile of the opening OP3b of the filter pattern FP3b on the reflective surface of the reflective electrode RE3 are different from the orthographic projection profile of the opening OP2b of the filter pattern FP2b on the reflective surface of the reflective electrode RE2.

[0069] For example, the orthographic projection outline of the opening OP1b of the filter pattern FP1b on the reflective electrode RE1 and the orthographic projection outline of the opening OP3b of the filter pattern FP3b on the reflective electrode RE3 can both be triangles, while the orthographic projection outline of the opening OP2b of the filter pattern FP2b on the reflective electrode RE2 can be hexagonal. More specifically, the overall orthographic projection outline of the openings OP1b, OP2b, and OP3b of the filter pattern FP1b, FP2b, and FP3b on the first substrate can be rhomboid. That is, in this embodiment, the transparent pattern TPb filled within the interconnected openings OP1b, OP2b, and OP3b of the filter patterns FP1b, FP2b, and FP3b can have a rhomboid top view outline along direction Z.

[0070] In this embodiment, the projected area of ​​the opening OP3b of the filter pattern FP3b on the reflective surface of the reflective electrode RE3 and the projected area of ​​the opening OP1b of the filter pattern FP1b on the reflective surface of the reflective electrode RE1 are both smaller than the projected area of ​​the opening OP2b of the filter pattern FP2b on the reflective surface of the reflective electrode RE2. In other words, the projected area of ​​the filter pattern FP1b on the reflective electrode RE1 and the projected area of ​​the filter pattern FP3b on the reflective electrode RE3 are both larger than the projected area of ​​the filter pattern FP2b on the reflective electrode RE2. Accordingly, the color quality perceived by the human eye when the reflective display panel 10B performs color display can be optimized.

[0071] Figure 5 This is a cross-sectional schematic diagram of a reflective display panel according to a fourth embodiment of the present invention. Figure 6 yes Figure 5 A top view of a portion of the film layer of a reflective display panel. Figure 5 for Figure 6 A cross-sectional view of the reflective display panel 10C at section line A-A'. Please refer to... Figure 5 and Figure 6 The reflective display panel 10C in this embodiment and Figure 4 The main difference between the reflective display panel 10B and the reflective display panel 10C in this embodiment is that, in order to further improve the display contrast and color performance, the reflective display panel 10C in this embodiment may also be provided with a light-shielding pattern layer.

[0072] In this embodiment, a light-shielding pattern layer may be disposed on the second substrate 200 and located between the second substrate 200 and the color filter layer CFL-C. For example, the light-shielding pattern layer includes a plurality of light-shielding patterns BM, which may be arranged along direction X and extend in direction Y. A light-shielding pattern BM may be provided between two adjacent reflective electrodes arranged along direction X. More specifically, a light-shielding pattern BM may overlap at the boundary of any two adjacent filter patterns arranged along direction X in the plurality of filter patterns of the color filter layer CFL-C.

[0073] It is particularly noteworthy that, in the color filter layer CFL-C of this embodiment, the configuration relationship of the opening OP1c of filter pattern FP1c, the opening OP2c of filter pattern FP2c, and the opening OP3c of filter pattern FP3c is similar to that of... Figure 4 The configuration relationship of the openings OP1b, OP2b, and OP3b of the filter pattern FP1b, filter pattern FP2b, and filter pattern FP3b of the CFL-B medium color filter layer. That is, in this embodiment, the openings OP1c, OP2c, and OP3c of the filter pattern FP1c, filter pattern FP2c, and filter pattern FP3c are interconnected, and their overall orthographic projection outline on the first substrate 100 is rhomboid.

[0074] However, for filter patterns of the same filter color, the projected area of ​​the filter pattern on its corresponding reflective electrode in this embodiment is relatively large. Figure 4 The area of ​​the filter pattern projected onto its corresponding reflective electrode is larger. In other words, the area of ​​the diamond-shaped opening of the color filter layer CFL-C in this embodiment projected onto the first substrate 100 is larger than that of the filter pattern in the first substrate 100. Figure 4 The diamond-shaped opening of the color filter layer CFL-B has a smaller projected area on the first substrate 100. That is, the projected area of ​​the transparent pattern TPc on the first substrate 100 in this embodiment is smaller than... Figure 4The transparent pattern TPb is the projected area on the first substrate 100.

[0075] In this embodiment, since a light-shielding pattern BM is provided between two adjacent filter patterns arranged along direction X, the diamond-shaped openings of the color filter layer CFL-C (i.e., the combination of openings OP1c, OP2c, and OP3c) will overlap the two light-shielding patterns BM. Notably, by adjusting the width of the light-shielding pattern BM, the opening design flexibility of the color filter layer CFL-C can be increased.

[0076] In summary, in a reflective display panel according to an embodiment of the present invention, the color filter layer has two filter patterns overlapping different pixel structures and having different filter colors. The orthographic projection proportions of these two filter patterns on the reflective surfaces of their respective reflective electrodes are not the same, thus optimizing the visual quality of the reflective display panel during color display.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
