The fourth alignment pattern 442 does not overlap with the second substrate 420 and the touch electrode layer 430 and is spaced apart by a distance d between 0 mm and 5 mm. In step S55, the first substrate 410 does not have one side of the second substrate 420, and the pair of bit light sources 450 are sequentially passed through the first alignment pattern 412 and the fourth alignment pattern 444, by capturing the first alignment pattern. 412 a first alignment pattern signal and a fourth alignment pattern signal of the fourth alignment pattern 444, performing a pattern signal alignment on the first alignment pattern signal and the fourth alignment pattern signal to enable the flexible circuit When the board 440 and the touch electrode layer 430 are joined, a pair of positions is achieved.
要說明的是，第四對位圖案444與第二基板420及觸控電極層430皆不重疊並間隔有一距離d之設計，目的是為了降低軟性電路板440本身之彎曲特性所造成的封裝對位誤差，在本實施例中，當距離d為3.5mm時，將具有最佳精準度封裝對位效果。 It should be noted that the fourth alignment pattern 444 does not overlap with the second substrate 420 and the touch electrode layer 430 and is spaced apart by a distance d. The purpose is to reduce the package characteristics caused by the bending characteristics of the flexible circuit board 440 itself. The bit error, in this embodiment, when the distance d is 3.5 mm, will have the best precision package alignment effect.
第三實施例相較於傳統封裝對位裝置10，傳統封裝對位裝置10無法適用於當影像感應器位於薄膜電晶體陣列110不具有觸控電極層130之一平面時，傳統封裝對位裝置10將無法提供影像感應器擷取第一對位圖案132與第二對位圖案142之對位資訊。而本實施例之觸控顯示裝置40，其中第一基板410更設計具有第一對位圖案412，以及軟性電路板440更設計具有第四對位圖案444，因此可以不受限於穿透式影像感應器位於第一基板410不具有第二基板420之一側邊之限制，其可直接利用第一對位圖案412與第四對位圖案444來作封裝對位製程，就可以精準地完成封裝對位製程，故可以降低製作成本。 Compared with the conventional package alignment device 10, the conventional package alignment device 10 cannot be applied to a conventional package alignment device when the image sensor is located on a plane of the thin film transistor array 110 without the touch electrode layer 130. 10 will not be able to provide the image sensor to capture the alignment information of the first alignment pattern 132 and the second alignment pattern 142. In the touch display device 40 of the present embodiment, the first substrate 410 is further designed to have a first alignment pattern 412, and the flexible circuit board 440 is further configured to have a fourth alignment pattern 444, so The image sensor is located on the first substrate 410 and has a limitation of one side of the second substrate 420. The first alignment pattern 412 and the fourth alignment pattern 444 can be directly used for the package alignment process, and the image alignment process can be accurately performed. The package alignment process can reduce the production cost.
綜上所述，本發明之觸控顯示裝置及其對位方法，係藉由在第二基板設計具有透光區，利用穿透式影像感應器搭配不同模組之對位電極來達到封裝對位製程，其不需再額外增加校準機台的數量，就可以精準地完成封裝對位製程，故可以降低製作成本。或是僅在遮光區外之一特定距離內，利用穿透式影像感應器分別搭配不同基板之對位圖案來達到封裝對位製程，其不需再額外增加校準機台的數量，就可以精準地完成封裝對位製程，故可以降低製作成本。 In summary, the touch display device and the alignment method thereof of the present invention achieve a package pair by using a transmissive image sensor with a matching electrode of a different module in a second substrate design having a light transmitting region. The bit process can accurately complete the package alignment process without additional number of calibration machines, so the manufacturing cost can be reduced. Or use the transmissive image sensor to match the alignment pattern of different substrates to achieve the package alignment process only at a certain distance outside the shading area, which can be accurately adjusted without additional calibration machine number. The package alignment process is completed, so the manufacturing cost can be reduced.
