Abstract
Description
本發明係關於一種蓋板結構及一種顯示裝置。 The present invention relates to a cover structure and a display device.
隨著科技的進步，發展出了各式各樣的顯示裝置，例如：反射式顯示裝置。反射式顯示裝置係藉由反射自外界光源所入射之光線來顯示畫面，因此無須搭載背光源，而具有輕薄的特性，並可節省電能。然而，當無外界光源照射時，反射式顯示器則無法顯示畫面。因此，為了拓展反射式顯示器的應用性，通常會在反射式顯示器上設置一前光模組來提供反射式顯示器足夠的光線。 With the advancement of technology, various display devices have been developed, such as reflective display devices. The reflective display device displays a picture by reflecting light incident from an external light source, so that it does not need to be equipped with a backlight, but has a thin and light characteristic and can save power. However, when there is no external light source, the reflective display cannot display the picture. Therefore, in order to expand the applicability of the reflective display, a front light module is usually provided on the reflective display to provide sufficient light for the reflective display.
一般來說，前光模組包含光源、導光板及印有油墨層的保護蓋板。保護蓋板係以印有油墨層的表面與導光板黏合。然而，為了保護導光板，保護蓋板通常會具有較厚的厚度，因此，從保護蓋板的外表面至油墨層的距離會較大。當光線從導光板進入到保護蓋板中後，光線容易在保護蓋板的外表面以及油墨層之間反射後再出射，而使得油墨層的附近發生漏光問題，進而不利地影響反射式顯示裝置的顯示品質。類似地，上述漏光問題在反射式顯示器反射自外界 光源所入射之光線時亦會發生。並且，上述漏光問題在油墨層的顏色為淺色時會特別嚴重。 Generally, the front light module includes a light source, a light guide plate, and a protective cover plate printed with an ink layer. The protective cover is bonded to the light guide plate with the surface printed with the ink layer. However, in order to protect the light guide plate, the protective cover plate usually has a thick thickness, and therefore, the distance from the outer surface of the protective cover to the ink layer is large. When the light enters the protective cover from the light guide plate, the light is easily reflected after the outer surface of the protective cover and the ink layer, and then the light leakage occurs in the vicinity of the ink layer, thereby adversely affecting the reflective display device. Display quality. Similarly, the above-mentioned light leakage problem also occurs when the reflective display reflects light incident from an external light source. Moreover, the above problem of light leakage is particularly serious when the color of the ink layer is light.

The materials of the other optical adhesive layers mentioned later may also refer to the material of the optical adhesive layer 264.
在一實施方式中，反射式顯示器130為電子紙顯示器(electronic paper displays，EPD)，因此，顯示裝置200為電子紙顯示裝置。然而，前光模組FL1可應用於其他需要前光模組的顯示裝置中。 In one embodiment, the reflective display 130 is an electronic paper display (EPD), and thus, the display device 200 is an electronic paper display device. However, the front light module FL1 can be applied to other display devices that require a front light module.
請同時參照第1圖及第2圖，前光模組FL1包含一導光板210、一光源220、一透光基材230、一第一遮光層240、一透光覆蓋層250及一光學膠層262，其中，透光基材230、第一遮光層240及透光覆蓋層250構成一蓋板結構CS1。顯示區110為被第一遮光層240所環繞的區域，而非顯示區120則為被第一遮光層240所覆蓋的區域。導光板210具有一上表面S1、一下表面S2及介於上表面S1及下表面S2間的一側面S3。光源220設置於導光板210的側面S3旁。透光基材230位於導光板210的上表面S1上，且具有一平坦上表面S4及一下表面S5。第一遮光層240設置於透光基材230的平坦上表面S4的邊緣上，並直接接觸平坦上表面S4。透光覆蓋層250位於第一遮光層240及透光基材230上。 Referring to FIG. 1 and FIG. 2 simultaneously, the front light module FL1 includes a light guide plate 210, a light source 220, a transparent substrate 230, a first light shielding layer 240, a light transmissive cover layer 250, and an optical adhesive. The layer 262, wherein the light-transmitting substrate 230, the first light-shielding layer 240 and the light-transmitting cover layer 250 constitute a cover structure CS1. The display area 110 is an area surrounded by the first light shielding layer 240, and the non-display area 120 is an area covered by the first light shielding layer 240. The light guide plate 210 has an upper surface S1, a lower surface S2, and a side surface S3 between the upper surface S1 and the lower surface S2. The light source 220 is disposed beside the side surface S3 of the light guide plate 210. The light transmissive substrate 230 is located on the upper surface S1 of the light guide plate 210 and has a flat upper surface S4 and a lower surface S5. The first light shielding layer 240 is disposed on the edge of the flat upper surface S4 of the light transmissive substrate 230 and directly contacts the flat upper surface S4. The light transmissive cover layer 250 is located on the first light shielding layer 240 and the light transmissive substrate 230.
透光基材230可作為保護導光板210的蓋板，且可為剛性基材或軟性基材。舉例來說，透光基材230為玻璃基材、陶瓷基材或塑膠基材。在一實施方式中，透光基材230 的材料包含玻璃、聚甲基丙烯酸甲酯(polymethylmethacrylate，PMMA)、聚碳酸酯(polycarbonate，PC)、聚對苯二甲酸乙二醇酯(polyethylene terephthalate，PET)、環烯烴聚合物(cyclo-olefin polymers，COP)、環烯烴共聚物(cyclic olefin copolymer，COC)、聚乙烯(polyethylene，PE)、聚醚醚酮(polyetheretherketone，PEEK)、聚萘二甲酸乙二醇酯(polyethylene naphthalate，PEN)、聚醯亞胺(polyimide，PI)、聚醚醯亞胺(polyetherimide，PEI)、或其組合。透光基材230可為單層結構或是多層結構。舉例來說，透光基材230可為由PMMA及PC所構成的多層結構。 The light transmissive substrate 230 can serve as a cover for protecting the light guide plate 210, and can be a rigid substrate or a soft substrate. For example, the light transmissive substrate 230 is a glass substrate, a ceramic substrate, or a plastic substrate. In one embodiment, the material of the transparent substrate 230 comprises glass, polymethylmethacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (polyethylene terephthalate, PET), cyclo-olefin polymers (COP), cyclic olefin copolymer (COC), polyethylene (PE), polyetheretherketone (PEEK), polynaphthalene dicarboxylic acid Polyethylene naphthalate (PEN), polyimide (PI), polyetherimide (PEI), or a combination thereof. The light transmissive substrate 230 may have a single layer structure or a multilayer structure. For example, the light transmissive substrate 230 can be a multilayer structure composed of PMMA and PC.
在一實施方式中，第一遮光層240為印刷油墨層，由於透光基材230可作為承載第一遮光層240的載板，因此第一遮光層240可透過一般的印刷方法直接形成於透光基材230的平坦上表面S4上，印刷方法例如為旋轉塗佈(spin coating)、網版印刷(screen printing)、凹版印刷(gravure printing)、狹縫式塗佈(slot die coating)、噴墨式印刷(ink jet printing)、蒸鍍(deposition)、噴塗(spray coating)、或濺鍍(sputtering)。在一實施方式中，第一遮光層240可包含複數個油墨層，且各層油墨層可藉由相同或不同的印刷方法來形成，以促使第一遮光層240的外觀更具變化性。在另一實施方式中，第一遮光層240為光阻層，由於透光基材230可作為承載第一遮光層240的載板，因此第一遮光層240可透過一般的形成光阻的方法直接形 成於透光基材230的平坦上表面S4上，例如，形成光阻的方法可包括塗佈、曝光及顯影的步驟。綜上所述，由於不需額外增加黏膠層來黏合透光基材230及第一遮光層240，蓋板結構CS1會較為輕薄。第一遮光層240的顏色可為深色或淺色，淺色例如白色。並且，為了符合各種外觀設計需求，第一遮光層240的圖案可為不規則。在另一實施例中，第一遮光層240可以形成在透光覆蓋層250上，形成方式可參考上述方法，不再贅述。 In one embodiment, the first light shielding layer 240 is a printing ink layer. Since the light transmitting substrate 230 can serve as a carrier for carrying the first light shielding layer 240, the first light shielding layer 240 can be directly formed through a general printing method. On the flat upper surface S4 of the light substrate 230, the printing method is, for example, spin coating, screen printing, gravure printing, slot die coating, and spraying. Ink jet printing, deposition, spray coating, or sputtering. In an embodiment, the first light shielding layer 240 may include a plurality of ink layers, and each layer of ink layers may be formed by the same or different printing methods to promote the appearance of the first light shielding layer 240 to be more versatile. In another embodiment, the first light shielding layer 240 is a photoresist layer. Since the transparent substrate 230 can serve as a carrier for carrying the first light shielding layer 240, the first light shielding layer 240 can transmit a general photoresist forming method. Directly formed on the flat upper surface S4 of the light-transmitting substrate 230, for example, a method of forming a photoresist may include a step of coating, exposing, and developing. In summary, since the adhesive layer is not additionally added to bond the transparent substrate 230 and the first light shielding layer 240, the cover structure CS1 is relatively light and thin. The color of the first light shielding layer 240 may be dark or light, and light colors such as white. Moreover, in order to meet various design requirements, the pattern of the first light shielding layer 240 may be irregular. In another embodiment, the first light shielding layer 240 may be formed on the light transmissive cover layer 250. For the manner of formation, refer to the above method, and details are not described herein.
透光覆蓋層250包含一硬塗層(hard coating layer，HC layer)、一抗眩光層(anti-glare layer，AG layer)或其組合。舉例來說，透光覆蓋層250可為硬塗層、抗眩光層、或包含至少一硬塗層及至少一抗眩光層的疊層。由於硬塗層及抗眩光層本身具有黏性，透光覆蓋層250可直接接觸第一遮光層240的上表面並與第一遮光層240的上表面黏合。由於不需額外增加黏膠層來黏合透光基材230、第一遮光層240及透光覆蓋層250，蓋板結構CS1會較為輕薄。 The light transmissive cover layer 250 comprises a hard coating layer (HC layer), an anti-glare layer (AG layer) or a combination thereof. For example, the light transmissive cover layer 250 can be a hard coat layer, an anti-glare layer, or a laminate comprising at least one hard coat layer and at least one anti-glare layer. Since the hard coat layer and the anti-glare layer itself have adhesiveness, the light-transmitting cover layer 250 may directly contact the upper surface of the first light-shielding layer 240 and adhere to the upper surface of the first light-shielding layer 240. Since the adhesive layer is not additionally added to bond the light-transmitting substrate 230, the first light-shielding layer 240 and the light-transmitting cover layer 250, the cover structure CS1 is relatively light and thin.
一般來說，可藉由將熱固化型組合物或光固化型組合物塗佈於透光基材230及第一遮光層240上以形成硬塗層。換句話說，硬塗層本身即具有黏性而可黏合於透光基材230及第一遮光層240上。塗佈方法包含但不限於旋轉塗佈法、浸漬法、噴塗法、狹縫塗佈法、棒塗佈法、浸潤法、輥塗佈法、凹版塗佈法及模嘴塗佈法。 Generally, a hard coat layer can be formed by applying a thermosetting composition or a photocurable composition onto the light-transmitting substrate 230 and the first light-shielding layer 240. In other words, the hard coat layer itself is viscous and can be bonded to the light-transmitting substrate 230 and the first light-shielding layer 240. The coating method includes, but is not limited to, spin coating, dipping, spraying, slit coating, bar coating, wetting, roll coating, gravure coating, and die coating.

First, the groove T is etched along the edge of a transparent substrate (not shown) to form the transparent substrate 232. The light transmissive substrate 232 may have a central portion CP and an edge portion EP surrounding the central portion CP, and a groove T above the edge portion EP surrounds the central portion CP. Next, a light shielding layer 244 is formed in the recess T, that is, a light shielding layer 244 surrounding the central portion CP is formed on the edge portion EP. Next, the light transmissive cover layer 252 is further formed to cover the central portion CP of the light transmissive substrate 232 and the light shielding layer 244. In one embodiment, the light shielding layer 244 is coplanar with the upper surface S6 of the central portion CP of the light transmissive substrate 232. For the material and formation method of the light shielding layer 244, reference may be made to the material and formation method of the first light shielding layer 240 described above. Since the light shielding layer 244 can be a printing ink layer or a photoresist layer, the light shielding layer 244 can be directly formed on the light transmitting substrate 232 to directly contact the light transmitting substrate 232. Since the adhesive layer 232 and the light shielding layer 244 are bonded without additionally adding an adhesive layer, the cover structure CS6 is relatively light and thin.
在一實施方式中，透光基材252的厚度T4佔透光基材232、遮光層244及透光基材252的總厚度T5的1%~33%。在另一實施方式中，透光基材252的厚度T4佔透光基材232、遮光層244及透光基材252的總厚度T5的1%~15%。 In one embodiment, the thickness T4 of the light-transmitting substrate 252 is 1% to 33% of the total thickness T5 of the light-transmitting substrate 232, the light-shielding layer 244, and the light-transmitting substrate 252. In another embodiment, the thickness T4 of the light-transmitting substrate 252 is 1% to 15% of the total thickness T5 of the light-transmitting substrate 232, the light-shielding layer 244, and the light-transmitting substrate 252.
綜上所述，在本發明的實施方式中，遮光層皆直接接觸透光基材，並且，透光覆蓋層可直接覆蓋遮光層及透光基材，或是透過光學膠層與遮光層及透光基材黏合。具有上述結構設計的蓋板結構能夠盡可能地縮短遮光層的上表面至透光覆蓋層的上表面的距離。因此，當外界光源或是前光模組中的光源所放出的光線經反射式顯示器反射之後，顯示裝置的非顯示區中不易發生漏光，而得以提升顯示裝置的顯示品質，並且具有輕薄的優勢。 In summary, in the embodiment of the present invention, the light shielding layer is directly in contact with the light transmissive substrate, and the light transmissive cover layer can directly cover the light shielding layer and the light transmissive substrate, or pass through the optical adhesive layer and the light shielding layer. The light transmissive substrate is bonded. The cover structure having the above structural design can shorten the distance from the upper surface of the light shielding layer to the upper surface of the light transmissive cover layer as much as possible. Therefore, when the light emitted by the external light source or the light source in the front light module is reflected by the reflective display, light leakage is less likely to occur in the non-display area of the display device, thereby improving the display quality of the display device and having the advantage of being thin and light. .
