以下參照各附圖詳細描述本發明的示例性實施例，且不意圖將本發明的技術原理限制於特定公開的實施例，而本發明的範圍僅由申請專利範圍限制，涵蓋了替代、修改和等同物。 Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is not intended to limit the technical principles of the present invention to specific disclosed embodiments, but the scope of the present invention is only limited by the scope of the patent application, covering substitutions, modifications and equivalent.
請參閱圖1至圖2所示，係為本發明一種可撓曲玻璃100的第一實施例，其包括一玻璃基板10，玻璃基板10一端具有一第一平直部11，另一端具有一第二平直部12，第一平直部11與第二平直部12之間設有一凹槽13及一對應凹槽13位置的彎曲連接部14。彎曲連接部14係可預先彎折成形，使第一平直部11與第二平直部12不在同一平面。於本發明實施例中，彎曲連接部14的曲率半徑介於10mm至300mm；於本實施例中，凹槽13為矩形。 Please refer to FIG. 1 to FIG. 2, which is a first embodiment of a flexible glass 100 of the present invention, which includes a glass substrate 10, one end of the glass substrate 10 has a first straight portion 11, and the other end has a A groove 13 and a curved connecting portion 14 corresponding to the position of the groove 13 are disposed between the second straight portion 12 , the first straight portion 11 and the second straight portion 12 . The curved connecting portion 14 can be bent in advance so that the first straight portion 11 and the second straight portion 12 are not on the same plane. In the embodiment of the present invention, the radius of curvature of the curved connecting portion 14 ranges from 10 mm to 300 mm; in this embodiment, the groove 13 is rectangular.
玻璃基板10具有一第一側面15及一第二側面16，凹槽13由第一側面15朝第二側面16的方向凹設，且凹槽13具有一槽底131，由槽底131往第二側面16延伸方向之厚度D1介於0.03至0.6mm之間，亦即具有凹槽13位置的玻璃厚度為0.03至0.6mm之間。其中厚度D1也是彎曲連接部14的厚度，並經實測結果，厚度D1若低於0.03mm時，玻璃於凹槽13處的厚度較薄，且在四點抗彎測 試下，強度明顯不足而易斷裂；而當玻璃於凹槽13處的厚度大於0.6mm時，其因厚度較厚而不易撓曲。因此於本發明實施例中，為使玻璃具一定強度及撓曲能力，前述厚度D1介於0.05至0.4mm之間為優選。而第一側面15至第二側面16的厚度D2介於1mm至4mm之間。 The glass substrate 10 has a first side 15 and a second side 16, the groove 13 is recessed from the first side 15 toward the second side 16, and the groove 13 has a groove bottom 131, from the groove bottom 131 to the second The thickness D1 of the extending direction of the two side surfaces 16 is between 0.03 and 0.6 mm, that is, the thickness of the glass with the groove 13 is between 0.03 and 0.6 mm. The thickness D1 is also the thickness of the curved connecting portion 14. According to the actual measurement results, if the thickness D1 is less than 0.03mm, the thickness of the glass at the groove 13 is relatively thin, and the four-point bending test Try it, the strength is obviously insufficient and it is easy to break; and when the thickness of the glass at the groove 13 is greater than 0.6mm, it is not easy to bend because of its thick thickness. Therefore, in the embodiment of the present invention, in order to make the glass have a certain strength and flexibility, it is preferable that the aforementioned thickness D1 is between 0.05 mm and 0.4 mm. The thickness D2 of the first side 15 to the second side 16 is between 1 mm and 4 mm.
第一平直部11對應凹槽13設有一連接於彎曲連接部14一端的第一連接段111，第二平直部12對應凹槽13設有一連接於彎曲連接部14另一端的第二連接段121，彎曲連接部14的寬度W1小於凹槽13的寬度W2，且彎曲連接部14的寬度W1介於20mm至60mm之間。其中，可撓曲玻璃100的彎曲方向是朝凹槽13方向，即第一平直部11與第二平直部12朝向凹槽13位置方向彎折。W2的尺寸範圍介於30mm至70mm。 The first straight portion 11 corresponds to the groove 13 and is provided with a first connecting section 111 connected to one end of the curved connecting portion 14, and the second straight portion 12 is provided with a second connection connected to the other end of the curved connecting portion 14 corresponding to the groove 13. In section 121 , the width W1 of the curved connection portion 14 is smaller than the width W2 of the groove 13 , and the width W1 of the curved connection portion 14 is between 20 mm and 60 mm. Wherein, the bending direction of the flexible glass 100 is toward the groove 13 , that is, the first straight portion 11 and the second straight portion 12 are bent toward the groove 13 . The size range of W2 is from 30mm to 70mm.
於本發明另一實施例中，玻璃基板10更包括一強固層20，強固層20全部或部分填入凹槽13，然而在其他實施例中，強固層20也可以是設置於第一側面15的全部或是局部。強固層20包括苯基之高分子聚合物、環氧樹脂或油墨，如為油墨則對應於玻璃的(Black Matrix,BM)區域，用以遮擋電子線路。此外，苯基之高分子聚合物的單體碳鏈長度為C6至C18之間，而能提升玻璃基板10防撞擊的功效，而環氧樹脂則作為增加強固層20的韌性以及增加與玻璃基板10的附著性，使玻璃基板10不易應力集中於凹槽13與彎曲連接部14產生斷裂，因此透過強固層20而提升凹槽13與彎曲連接部14的強度。而在其他實施例中，強固層20也可以是透明狀。 In another embodiment of the present invention, the glass substrate 10 further includes a reinforcing layer 20, the reinforcing layer 20 completely or partially fills the groove 13, but in other embodiments, the reinforcing layer 20 can also be disposed on the first side 15 all or part of. The reinforcement layer 20 includes phenyl polymer, epoxy resin or ink, and if it is ink, it corresponds to the (Black Matrix, BM) area of the glass and is used to shield the electronic circuit. In addition, the monomer carbon chain length of the phenyl polymer is between C6 and C18, which can improve the anti-collision effect of the glass substrate 10, and the epoxy resin is used to increase the toughness of the reinforcement layer 20 and increase the contact with the glass substrate. The adhesiveness of 10 makes it difficult for the glass substrate 10 to be broken due to stress concentration on the groove 13 and the curved connection portion 14 , so the strength of the groove 13 and the curved connection portion 14 is enhanced through the reinforcing layer 20 . In other embodiments, the strengthening layer 20 may also be transparent.
藉此，本發明可撓曲玻璃100除了藉由凹槽13提升整體玻璃的彎折能力外，且透過彎曲連接部14預先彎折成形的方式而能額外再增加彎折角度20度至40度，據以提升彎折的曲率，而適用於所需產品上。 In this way, the flexible glass 100 of the present invention can increase the bending angle by 20 degrees to 40 degrees by pre-bending the bending connecting part 14 in addition to improving the bending ability of the whole glass through the groove 13 , so as to increase the curvature of the bend and apply to the desired product.
