Description
本發明是有關於一種行動電子裝置的顯示模組結構，且特別是有關於一種具有觸控功能的行動電子裝置的顯示模組結構。 The invention relates to a display module structure of a mobile electronic device, and more particularly to a display module structure of a mobile electronic device with a touch function.
請同時參照圖1及圖2，圖1係繪示習知的一行動電子裝置的上視圖；圖2係繪示圖1之行動電子裝置的剖面線2-2’的剖面圖。在目前具有觸控功能的行動電子裝置100的顯示模組結構中，若就電子裝置的上視外觀而言，可分為可視區域102及外圍的阻光區域104。阻光區域104目前以油墨層110印刷覆蓋於外蓋玻璃112的內表面而形成。 Please refer to FIG. 1 and FIG. 2 at the same time.

請同時參照圖3及圖4，圖3係繪示根據本發明之一實施例所述之行動電子裝置，圖4係繪示圖3之行動電子裝置的剖面線4-4’的剖面圖。在具有觸控功能的行動電子裝置200的顯示模組結構中，若就電子裝置的上視外觀而言，包含可視區域202及外圍的阻光區域204。阻光區域204係以油墨層212印刷覆蓋於外蓋玻璃214的內表面而形成。上述的「內表面」係相對於外蓋玻璃214之能被外界碰觸之 「外表面」而言。 Please refer to FIG. 3 and FIG. 4 at the same time. FIG. 3 is a cross-sectional view of the mobile electronic device according to an embodiment of the present invention, and FIG. 4 is a cross-sectional line 4-4 'of the mobile electronic device of FIG. In the display module structure of the mobile electronic device 200 having a touch function, as far as the top view appearance of the electronic device is concerned, it includes a visible area 202 and a peripheral light blocking area 204. The light blocking region 204 is formed by printing and covering the inner surface of the cover glass 214 with the ink layer 212. The aforementioned "inner surface" is relative to the outer cover glass 214 that can be touched by the outside world. "Outer surface".
因油墨層212印刷覆蓋於外蓋玻璃214的內表面所形成可視區域202及阻光區域204之間的斷差，會造成顯示上不均勻的彩紋(mura)或黏貼時氣泡不易排出。具體而言，當顯示模組結構中的外蓋玻璃214與液晶顯示模組206(具有觸控感應功能的液晶顯示模組)以光學透光黏膠層208黏合彼此時，可視區域202及阻光區域204之間的油墨層212斷差坡之夾角θ通常會大於13°，因此造成顯示出光不均勻產生的彩紋(mura)或黏合時易產生氣泡的狀況。上述的彩紋(mura)泛指顯示器亮度不均勻造成各種痕跡的現象。 The gap between the visible area 202 and the light blocking area 204 formed by printing and covering the inner surface of the cover glass 214 with the ink layer 212 may cause uneven mura on the display or bubbles may not be easily discharged when pasted. Specifically, when the cover glass 214 and the liquid crystal display module 206 (a liquid crystal display module with a touch sensing function) in the display module structure are bonded to each other with an optically transparent adhesive layer 208, the visible area 202 and the resistance The included angle θ of the difference slope of the ink layer 212 between the light regions 204 is usually greater than 13 °, so that it causes the display of mura caused by uneven light or the condition that bubbles are liable to be generated during adhesion. The above-mentioned mura refers to a phenomenon in which various traces are caused by uneven brightness of a display.
相較於習知加厚光學透光黏膠層的解決方式，本發明另增一中介過渡層210覆蓋於油墨層212的全部表面及外蓋玻璃214的其餘內表面(除了油墨層212其餘內表面)，藉以填平油墨層212的斷差坡，進而降低油墨層212斷差坡的影響。 Compared with the conventional solution for thickening the optically transparent adhesive layer, another intermediary transition layer 210 is added to cover the entire surface of the ink layer 212 and the remaining inner surface of the outer cover glass 214 (except for the rest of the ink layer 212). Surface) to fill the gap of the ink layer 212, thereby reducing the influence of the gap of the ink layer 212.
在本實施例中，中介過渡層210的最大厚度(直接貼合於外蓋玻璃214內表面的部份)大於油墨層212的最大厚度(即油墨層212的最高點212a)。 In this embodiment, the maximum thickness of the intermediary transition layer 210 (the portion directly attached to the inner surface of the cover glass 214) is greater than the maximum thickness of the ink layer 212 (that is, the highest point 212a of the ink layer 212).
在本實施例中，中介過渡層210可以覆蓋於油墨層212的全部表面，更可以覆蓋於油墨層212的所有開孔區。開孔區可以是紅外線開孔204a、攝像開孔204b或閃光燈開孔204c等。 In this embodiment, the intermediary transition layer 210 may cover the entire surface of the ink layer 212, and may further cover all the open areas of the ink layer 212. The opening area may be an infrared opening 204a, a camera opening 204b, a flash opening 204c, or the like.
此外，中介過渡層210覆蓋於油墨層212的爬升 坡210a的坡角α較佳係小於或等於1.5°，藉以補償油墨層212的斷差坡，進而降低油墨層212斷差坡對顯示模組的影響。 In addition, the intermediate transition layer 210 covers the climb of the ink layer 212 The slope angle α of the slope 210 a is preferably less than or equal to 1.5 °, so as to compensate for the slope of the ink layer 212 and further reduce the influence of the slope of the ink layer 212 on the display module.
藉由新增的中介過渡層210，就無需加厚光學透光黏膠層208而同樣能降低油墨層212斷差坡的影響。因此，超薄光學透光黏膠層208就能用以黏合外蓋玻璃214與液晶顯示模組206，使液晶顯示模組能保持薄形化。 With the newly-added intermediary transition layer 210, there is no need to thicken the optically transparent adhesive layer 208 and the influence of the slope of the ink layer 212 can also be reduced. Therefore, the ultra-thin optically transparent adhesive layer 208 can be used to bond the cover glass 214 and the liquid crystal display module 206, so that the liquid crystal display module can be kept thin.

The material can be a photoresist material or an optical resin material with good optical transmittance. It has high flatness, high transmittance, and colloidal or liquid characteristics.
上述具有觸控感應功能的液晶顯示模組206可以是內嵌觸控感應結構的液晶顯示模組或外加控感應結構的液晶顯示模組。在本實施例中，因發明的重點不在於液晶顯示模組，因此液晶顯示模組206的內容細節不再增加圖式贅述。 The above-mentioned liquid crystal display module 206 with a touch sensing function may be a liquid crystal display module with a built-in touch sensing structure or a liquid crystal display module with a controlled sensing structure. In this embodiment, since the focus of the invention is not on the liquid crystal display module, details of the content of the liquid crystal display module 206 will not be described in detail.
綜合以上所述，本發明之行動電子裝置的顯示模組結構提供一搭配超薄光學透光黏膠層的方式補償油墨層斷差的問題，藉以將彩紋(mura)或氣泡的問題降到最低，且在無需加厚光學透光黏膠層的狀況下，而同樣能降低油墨層斷差坡的影響。 To sum up, the display module structure of the mobile electronic device of the present invention provides an ultra-thin optical transparent adhesive layer to compensate the problem of ink layer breakage, thereby reducing the problem of mura or air bubbles. The lowest, and without the need to thicken the optically transparent adhesive layer, it can also reduce the impact of the ink layer break slope.
雖然本發明已以數個實施例揭露如上，然其並非用以限定本發明，在本發明所屬技術領域中任何具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍 所界定者為準。 Although the present invention has been disclosed as above with several embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field to which the present invention pertains can make various modifications without departing from the spirit and scope of the present invention. Changes and retouching, so the protection scope of the present invention should be regarded as the scope of patent application attached The ones defined shall prevail.
