This type of panel is a display panel that can use reflected light as a backlight application. , such as an electronic paper that emphasizes high contrast. In this type of reflective display panel, the color of the substrate is usually light-colored, and the touch panel can also use metal wires as the touch circuit.

Therefore, in one embodiment, the electrode structure in the touch panel is made of metal conductive material. In order to effectively suppress the reflection of the metal and harmonize with the color of the substrate in the panel, the electrode structure proposed in the embodiment forms a color on the metal conductive layer. The main purpose of this color reconciliation layer is to shield the metal conductive layer to avoid metal reflection, and at the same time to reconcile the color of the substrate to avoid visual interference. The chromaticity reconciliation layer proposed by the embodiment can further ensure the light transmittance of the whole panel and the metal conductivity of the electrode structure.

In the touch panel device proposed by the present invention, the metal conductive layer is formed by metal conductive material, which forms the main body of the electrode structure of the panel. The touch panel can be a reflective display panel, including a flexible reflective display panel. The reflective display panel mainly relies on the surrounding ambient light source to achieve the display effect, so it is necessary to consider eliminating the ambient light in the metal conductive layer. The resulting metal is reflective, so a hue-harmonic layer formed on the metal conductive layer is proposed.

According to one embodiment, the chromaticity blending layer on the electrode structure in the display panel is a light-colored whitening layer. This whitening layer can not only eliminate metal reflection, but also has corrosion resistance, which can reduce the use of metal electrodes in the touch panel. The obvious metal reflection (metal visibility) at the time of technology, and the protection of metal electrodes from the influence of high temperature and high humidity in the environment, increase the visual quality of reflective displays, such as reflective displays with white screen substrates such as e-paper and e-books wait.

One of the formation methods of the above-mentioned chromaticity adjustment layer may be to directly coat related materials on the metal electrode structure, or to form by sputtering or evaporation.

According to a preferred embodiment, the coating used in the present invention comprises 25%-50% by weight of phenolic resin, 1%-5% by weight of photosensitive compound, and 1% by weight of organic colored polymer dye. %-20%, the weight percentage of the solvent is 40%-70%, wherein the solvent can be propylene glycol methyl ether acetate. The mixed mixture of the aforementioned four is blended with the inorganic colored dye, and the weight percentage of _the mixture is _60-99 %. The method of mixing 1%-40% by weight is used in the color tone and layer paint used in the utility model.

According to a preferred embodiment, the weight percent of the phenolic resin contained in the chromaticity and layer coating of the present invention is 5%-45%, the weight percent of the photosensitive compound is 1%-15%, and the weight percent of the organic colored polymer dye is 1%-20%, the weight percentage of the solvent is 45%-90%, wherein the solvent can be one of the group consisting of propoxyethyl acetate, propylene glycol methyl ether acetate, propylene glycol methyl ether and mixtures thereof. The mixture of the aforementioned four (phenolic resin, photosensitive compound, organic colored polymer dye and solvent) is blended with an inorganic colored dye, and the weight percentage of the mixture is 60-99%. The inorganic colored dye is a white material such as SiO ₂ or TiO ₂ or calcium carbonate and other white series micron-scale powders are mixed in a manner of 1%-40% by weight and are used in the cost utility model.

In addition, if the color tone layer of the present invention is aimed at whitening, it can also be made by using a silver-white metal directly coated on the metal electrode structure and then processed to make it have a rough surface. Silver-white metals such as silver, nickel, chromium, titanium, aluminum, molybdenum, tungsten, copper and other elements or alloys of their combinations, such as copper-nickel alloys, commonly known as cupronickel.

The color tone layer formed on the metal conductive layer in the electrode structure is only formed on the surface of the metal conductive layer structurally, can be completely covered on the metal electrode with a fixed thickness, and can be formed on the metal electrode with a drop-shaped cross section , can be formed on the metal electrode with the particle surface.

First, please refer to FIG. 2 for a structural schematic diagram of a display panel applying the electrode structure of the present invention with a chromaticity reconciliation layer.

The figure shows a display panel structure, with a reflective panel 203 below, a substrate 2 in the middle, and optical glue 24 between the two, and electrode structures 21a, 21b on both sides of the substrate 2 respectively. According to a preferred embodiment 1, the substrate 2 is made of a light-transmitting material, and forms a touch panel with the electrode structures 21a and 21b.

The touch panel will form a reflective display panel, the upper part is combined with the cover plate 201 above the panel through the optical glue 23, and the lower part is also combined with the reflective panel through the optical glue 24, thus forming the display panel structure disclosed in the present utility model.

In addition, when an external light source is irradiated from above along the dotted line in the figure, it passes through the cover plate 201, the optical glue 23, the substrate 2, and the lower optical glue 24, and reaches the reflective panel 203, which is then reflected as the second reflected light 206 , so the human eye will see the first reflected light 205 and the second reflected light 206 at the same time.

In this example, the first reflected light 205 is the reflected light reflected from the electrode structure 21a, which is a kind of metal reflective light, and its chromaticity has a contrasting color difference with the color of the substrate of the reflective panel 203 (for example, electronic paper products are usually white). It will make it easier for the human eye to observe the wiring of the metal electrodes.

In order to avoid the metal reflection seen when the user watches the display panel using the metal wire electrode, the utility model proposes a chromaticity reconciliation layer formed on the metal wire electrode, which can not only avoid the phenomenon that the metal reflects the external light source, but also It can adjust the reflected light of the panel substrate.

The embodiment in which the chromaticity reconciliation layer is formed on the electrode structure is shown in FIG. 3A. The main structure of the electrode is a substrate 31, a conductive layer 32 formed by metal wires, and a conductive layer 32 formed on the surface of the conductive layer 32 and evaporated by coating or sputtering. The chromaticity reconciliation layer 33 formed by plating.

In the embodiment shown in FIG. 3C , the chromaticity blending layer 35 of this example is formed on the conductive layer 32 with a drop-shaped cross section, which can reduce metal reflection and provide anti-corrosion effect under more viewing angles. This example also shows an embodiment in which the color-harmony layer 35 completely covers the conductive layer 32 .

In the embodiment of completely covering the conductive layer 32 shown in FIG. 3D , the color tone blending layer 36 is formed on the conductive layer 32 in the form of particles, which can further reduce metal reflection and provide anti-corrosion effect.

In FIG. 3E , the color tone blending layer 37 is formed on the conductive layer 32 which itself has a particle surface, and completely covers the conductive layer 32 , so that the conductive layer 32 can reduce metal reflection.

The substrate 31 mentioned in each of the above-mentioned embodiments is the base material of the electrode structure in the panel structure, and the material of the substrate can be PET (Polyethylene terephthalatem, polyethylene terephthalate), PEN (polyethylene naphthalate), COC (Cyclic Olefin Copolymer), LCP (liquid crystal polymer), PI (Polyimide, polyimide), PEI (polyetherimide) or PPSU (polyphenyl sulfone) and their combinations. The metal conductive layer 32 on the substrate 31 can be made of copper, aluminum, nickel, iron, gold, silver, stainless steel, tungsten, chromium or titanium, or an alloy of multiple materials therein. The chromaticity reconciliation layers 33, 34, 35, 36, 37 can be whitening layers formed by lighter color materials, the material is paint or silver-white metal, which is formed by directly coating on the surface of the metal electrode structure, and silver-white metal is used It can be reprocessed to have a rough surface. The optical requirements of the color reconciliation layer are L<90, a±2, b±2, and reflectance less than 30.

4A-4E then show a flowchart of an embodiment of forming a hue-harmonic layer in a panel structure.

At the beginning of the process, a substrate 41 is first prepared, as shown in Figure 4A; then a conductive layer 42 is formed on the substrate 41, as shown in Figure 4B; and then a color reconciliation layer 43 is formed on the conductive layer 42, such as a whitening layer formed of light-colored materials , as shown in Figure 4C. Ways to form the original state of the color tone layer 43 include coating materials on the conductive layer 42 by screen printing, doctor blade, wire rod or rotation.

According to the needs of the electrode structure, the next step is to pattern the chromaticity reconciliation layer 43, etch along the conductive layer 42 to be exposed, such as patterning the relevant coating material along the direction of the metal wire electrode, as shown in Figure 4D, and the pattern For example, photomask exposure, development, etching or laser beam engraving can be used. Another method is to first hydrophilize the surface of the metal conductor, so that the water-based coating can selectively adhere to the surface of the metal conductor instead of hydrophobic PET surface, but not limited to. In this way, the color tone blending layer 43' that only covers the metal conductor can be formed in simple steps.

The steps continue as shown in FIG. 4E , continue to etch away the part that is not used as the electrode layer to form a patterned conductive layer 42' on the substrate 41, and a corresponding color tone layer 43' on the surface.

FIG. 5 shows a schematic diagram of an embodiment of a display panel structure utilizing the electrode structure with a hue-harmony layer of the present invention.

The figure shows a reflective panel structure, the bottom is provided with a reflective panel 51, such as a liquid crystal panel, and the touch panel above the structure is combined with an optical glue 53. The touch panel includes a substrate 55 and an electrode structure 57 formed on the substrate 55. , 58.

In this example, at least one electrode structure 57 and 58 is disposed on the substrate 55 , and the design of the electrode structure can be as in the above-mentioned embodiments shown in FIGS. 3A to 3E .

In this example, a hue-harmonic layer 572 is formed on the conductive layer 571 in the electrode structure 57 ; and a hue-harmony layer 582 is formed on the conductive layer 581 in the electrode structure 58 . The hue-harmony layers 572 and 582 can be in different forms, and the colors of the hue-harmony layers 572 and 582 can be designed according to the color of the substrate of the reflective panel 51 . For example, if the base color of the electronic paper is white, the chromaticity of the chromaticity blending layers 572 and 582 can be adjusted to be close to or consistent with the color of the substrate, so that reflected light with consistent chromaticity can be generated when an external light source is incident. For example, the first reflected light 505 is generated by the reflection of the metal electrode 58, and the second reflected light 506 is generated by the reflection of the reflective panel 51. The chromaticity reconciliation layers 572 and 582 will make the chromaticity of the two reflected lights similar, so that the human eye can observe the display. There is no color difference in the picture, and the visual discomfort caused by the electrode structure of the metal wire is reduced.

According to an embodiment, the thickness of the conductive layers 571 and 581 is preferably in the range of 0.001 μm-15 μm, and the thickness of the color tone blending layers 572 and 582 is preferably in the range of 0.005 μm-15 μm. The widths of the conductive layers 571, 581 and the chromaticity blending layers 572, 582 (such as the wire width of metal wires) are preferably 1 μm-30 μm.

FIG. 6 shows another embodiment of the electrode structure of the present invention with a hue-harmonic layer.

This legend shows that there can be more than one layer of color harmony layer on the metal conductive layer. For example, a conductive layer 63 is formed on a substrate 61 in the figure. Another second color harmony layer 66 is formed on the color harmony layer 65, thus the corrosion resistance and environmental adaptability of the electrode structure can be improved, and the second color harmony layer 66 assists the first color harmony layer 65 to achieve Adjust the color chromaticity and light reflection ability of the overall electrode.

In addition to the above-mentioned materials for realizing the first color-harmony layer 65 , the material of the second color-harmony layer 66 in this example can be light-colored oxide, light-colored polymer, silver-white metal and mixtures thereof. Silver-white metals such as silver, nickel, chromium, titanium, aluminum, molybdenum, tungsten, copper and other elements and alloys of their combinations (such as copper-nickel alloy, commonly known as white copper); light-colored oxides can be silicon oxide, titanium oxide, oxide Aluminum and its mixture; light-colored polymers can be silicone, etc. Wherein, in the mixture of the second color reconciliation layer 66 , the proportion of the light-colored polymer can be 10-90%, and the proportion of the silver-white metal in the light-colored oxide can be 10-90%. The thickness of the second color-harmony layer 66 is preferably in the range of 0.001 μm to 1 μm; the reflectivity of the second color-harmony layer 66 is in the range of 1% to 50%, preferably lower than 30%. In addition, the total reflectance generated by the first color-harmony layer 65 and the second color-harmony layer 66 should be lower than 30%.

The properties of the chromaticity blending layer can be represented by chromaticity coordinates composed of L (lightness), a (red-green) and b (yellow-blue). For example: when the electronic paper screen has no backlight and presents a pure white background, its reflectivity (reflectivity) should be less than 30%, the brightness (lightness) should be less than 90, and the red-green axis (a/-a axis) of the chromaticity coordinates should be between 2 and -2, the yellow-blue axis (b/-b axis) is between 2 and -2. Especially for electronic paper with a whiter background color, the color reconciliation layer with a brightness of less than 90% can be called a whitening layer.

Because of the metallic yellow color of copper in the metal electrodes of the touch panel, it is easy for the human eye to observe the yellowish metal reflection. Therefore, the first chromaticity reconciliation layer 65 can adjust the metal color of the metal electrode itself at the same time, so that the color of the metal electrode itself, such as the reflectance of the pure copper metal base material>50%, L>90%, a<0.1, b> 2. It is close to the pure white background color (Paperwhite) of the screen, reducing contrast color difference. The shade of the material itself of the first and second shade-harmonic layers 65, 66 may vary due to the thickness of the material. The second chromaticity reconciliation layer 66 can adjust the chromaticity of the first chromaticity reconciliation layer 65 to make it closer to the paper-like color or pure white of the screen, and has anti-reflection, anti-interference, anti-iridition, anti-wear, and scratch-resistant properties. characteristics.

The form of the chromaticity reconciling layer can refer to the embodiment of the electrode structure shown in FIG. 7A and FIG. 7B . 7A and 7B respectively show the electrode structures 73 and 74 on the substrate 71 in the panel structure. One of the electrode structures 73 and 74 with different designs can be selected as the electrode structure of the panel.

In FIG. 7A , an adhesive layer 731 is provided between the electrode structure 73 and the substrate 71 . The adhesive layer 731 strengthens the adhesion between the conductive layer 732 and the substrate 71 and can reduce the problem of the electrode structure 73 falling off due to the flexure of the substrate 71 . On the conductive layer 732 is a hue blending layer 733 .

The material of the next layer 732 includes one of the group consisting of polymer materials, oxide materials, metal materials and their composite materials. Polymer materials include acrylic, PET, PEI, PPSU, PI, PEDOT, Polyaniline, Polypyrrole or a combination of composite materials. The oxide can be an amorphous or polycrystalline oxide film or a powder structure. Wherein, the composition of the oxide may be titanium oxide, tantalum oxide, silicon oxide, aluminum oxide or a composite material combination thereof. Metals may include copper, silver, aluminum, molybdenum, nickel, chromium, tungsten, titanium, silicon, zinc, tin, iron and other alloys or composite combinations thereof. Two or three combinations of polymers, metals and oxides can also be obtained, such as: the combination of metals and oxides, the combination of polymers and metals, the combination of polymers and oxides or the combination of metals and oxides and polymers combination of composite materials. If a composite material is used, the proportion of the polymer is 10-90%, the proportion of the oxide is 10-90%, and the proportion of the metal is 10-90%. Oxide can also be a multilayer structure. For example, the thickness of titanium oxide is 900 nm, and the thickness of silicon oxide is 100 nm. The thickness of the next layer 732 is preferably in the range between 0.001 μm and 1 μm; the reflectivity needs to be in the range of 1% to 50%, preferably lower than 30%.

In FIG. 7B , the electrode structure 74 schematically shows that a roughening layer 743 is formed on the conductive layer 741 and the color tone blending layer 742 . The roughened layer 743 can reduce the reflection of the metal to enhance the invisibility to the naked eye. The roughening layer 743 can be formed by chemical etching (sulfuric acid, permanganic acid, etc.), mechanical physics or plasma cleaning (such as rolling, ion beam, corona, atmospheric plasma), etc., so the roughening layer 743 can be made of the same material as Subsequent shades are the same material as layer 742.

The roughened structure formed in the electrode structure 74 such as the roughened layer 743 can be formed by etching or other processing methods, or formed by electrolysis, sputtering or deposition of other materials.

If the roughening layer 743 is formed by additionally coating materials such as ultraviolet glue or a silicone resin hardening layer, the material of the roughening layer 743 may be different from that of the lower hue-harmony layer 742 . The roughness (Ra centerline average roughness) of the roughened layer 743 preferably ranges from 0.001-0.2 μm, and the optimum roughness range is Ra=0.02-0.1 μm.

When forming a roughened layer on the electrode structure, refer to the schematic diagram of the embodiment shown in FIG. 8 .

The main body of the panel structure in this example includes a reflective panel 81 , a substrate 83 and an upper cover 85 , and the three are bonded with optical glue 801 , 802 . In the electrode structure 87 formed on the substrate 83, metal wires are used as conductors, that is, the conductive layer 872. In order to eliminate metal reflection and adjust the color of the substrate of the reflective panel 81, a hue blending layer 873 is formed on the conductive layer 872, and The lower part is bonded to the substrate 83 through the adhesive layer 871 .

To strengthen the scattering of incident light and eliminate metal reflection, a rough layer 874 can be formed on the chromaticity blending layer 873. The roughness of the rough layer 874 can reduce the haze (Haze) feeling of the human eye due to the relationship of the optical glue 802 . In addition, because the optical glue 802 fills in the relationship between the rough surface of the electrode structure 87, the color of the hue blending layer 873 can be additionally made closer to the color of the substrate of the reflective panel 81, such as pure white or similar to the substrate of electronic paper. The color white matrix is more similar to the chromaticity.
