Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings.
Unless otherwise defined, all words (including technical and scientific terms) used herein have their ordinary meaning as understood by those skilled in the art. Furthermore, the definitions of the above-mentioned words and phrases in general and in common use, in the context of this specification, should be read in a manner consistent with the context of the present invention. Unless otherwise explicitly defined, these terms are not to be construed in an idealized or overly formal sense.
Please refer to fig. 1 and fig. 2. Fig. 1 is a top view of a touch panel 100 according to an embodiment of the invention. Fig. 2 is a cross-sectional view taken along line a of fig. 1. In the present embodiment, as shown in fig. 1 and fig. 2, a touch panel 100 includes a light-transmitting plate 110, an inductive film 120, and an Optical Clear Adhesive (OCA) 130. The transparent plate 110 has a surface 111 and at least two positioning portions 112, the positioning portions 112 are located on the surface 111, the positioning portions 112 have two edges 113 connected to each other, the edges 113 of the positioning portions 112 are intersected at positioning points 114, the positioning points 114 are opposite to each other, virtual lines VL extend from the corresponding positioning points 114 of the edges 113, and the virtual lines VL are connected to each other to define a simulation region VR together. The sensing film 120 covers the surface 111, and the projection of the simulation region VR toward the sensing film 120 is located within the range of the sensing film 120. The optical adhesive 130 is connected between the transparent plate 110 and the sensing film 120. In practical applications, the transparent plate can be a Glass plate (CG).
In practical applications, a user can identify and grasp the position of the positioning point 114 and the position of the virtual line VL on the transparent plate 110, that is, the position of the simulation region VR is positioned, so that the liquid crystal panel (not shown) can be precisely attached to the transparent plate 110.
As described above, the positioning points 114 are opposite to each other, that is, as shown in fig. 1, the simulation region VR is at least partially located between the positioning points 114, and the positioning portion 112 is located outside the simulation region VR. Furthermore, in the present embodiment, the virtual lines VL extending from the two opposite positioning points 114 are perpendicular to each other, so that the simulation region VR is rectangular, such as a square or a rectangle. In the present embodiment, the positioning portion 112 has a square shape.
Generally, when the optical adhesive 130 connects the transparent plate 110 and the sensing film 120, bubbles are easily generated at a position close to the perimeter 121 of the optical adhesive 130 according to the characteristics of the optical adhesive 130. It is known from practical operation experience that the distance that the bubble moves toward the simulation region VR within the optical paste 130 exceeds about 0.3 mm or so.
In the present embodiment, the positioning portion 112 is made of a metal material. As can be seen from practical operation experience, the tolerance for disposing the positioning portion 112 on the surface 111 of the light-transmitting plate 110 is generally about more than about 0.1 mm.
Furthermore, it can be known from practical operation experience that the wide deviation of the position of the simulation region VR on the transparent plate 110 recognized and grasped by the user is generally more than about 0.5 mm.
Based on the distance that the bubble can move in the optical cement 130, the tolerance of the positioning portion 112 disposed on the surface 111, and the wide deviation of the position where the user recognizes and grasps the simulation region VR, in the present embodiment, the perpendicular distance D1 between the positioning point 114 and the perimeter 121 of the sensing film 120 is set to be greater than the sum of 0.3 mm, 0.1 mm, and 0.5 mm, that is, greater than about 0.9 mm. That is, when the optical adhesive 130 connects the transparent plate 110 and the sensing film 120, even if the optical adhesive 130 generates bubbles at a position close to the perimeter 121, and a tolerance occurs when the positioning portion 112 is disposed on the surface 111 of the transparent plate 110, and a deviation occurs when a user recognizes and grasps the position of the simulation region VR, since the vertical distance D1 is greater than about 0.9 mm, the chance of the bubbles moving from the position close to the perimeter 121 to the positioning point 114 or the virtual line VL within the optical adhesive 130 is reduced. Therefore, the positioning point 114 and the virtual line VL extending from the positioning point 114 are not easily covered by the bubbles, so that the positioning point 114 and the virtual line VL extending from the positioning point 114 can be easily identified and grasped by a user, and the user can accurately position the simulation area VR, thereby precisely attaching the liquid crystal panel to the transparent plate 110.
On the other hand, in the present embodiment, in consideration of the tolerance occurring when the positioning portion 112 is disposed on the surface 111 of the light-transmitting plate 110, the perpendicular distance D2 between one end of the edge 113 away from the corresponding positioning point 114 and the perimeter 121 of the sensing film 120 is greater than or equal to about 0.1 mm.
Thus, as mentioned above, since the perpendicular distance D1 is greater than about 0.9 mm and the perpendicular distance D2 is greater than or equal to about 0.1 mm, the length L of the edge 113 is at least greater than the sum of 0.9 mm and 0.1 mm, i.e., greater than about 1.0 mm. In practical applications, the length L of the edge 113 may range from about 1.0 mm to about 2.2 mm, but the invention is not limited thereto.
More specifically, in the present embodiment, the number of the positioning portions 112 is four. As shown in fig. 1, the virtual lines VL extending from the positioning portions 112 at least partially overlap the corresponding virtual lines VL extending from the adjacent positioning portions 112, so that the simulation regions VR defined by the virtual lines VL connected to each other are rectangular, such as square or rectangle.
Fig. 3 is a top view of a touch panel 100 according to another embodiment of the invention. In the present embodiment, as shown in fig. 3, the positioning portion 112 is formed by two strip-shaped structures meeting in an L shape, and the strip-shaped structures meet at the positioning point 114. More specifically, the strip-shaped structure of the positioning portion 112 extends at least partially from the positioning point 114 for the user to identify and grasp.
In conclusion, compared with the prior art, the technical scheme of the invention has obvious advantages and beneficial effects. Through the technical scheme, considerable technical progress can be achieved, the industrial wide utilization value is achieved, and the method at least has the following advantages: when the optical cement connects the transparent board and the sensing film, even if the optical cement generates bubbles at a position close to the periphery, the positioning part is arranged on the surface of the transparent board with tolerance, and the user identifies and captures the position of the simulation area with deviation, because the vertical distance is greater than about millimeter, the chance that the bubbles move to the positioning point or the virtual line in the optical cement from the position close to the periphery is reduced. Therefore, the positioning point and the virtual line extending from the positioning point are not easily covered by the bubbles, so that the positioning point and the virtual line extending from the positioning point can be easily identified and grabbed by a user, the user can accurately position the simulation area, and the liquid crystal panel can be accurately attached to the transparent plate.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
