Description

面板制造方法 技术领域
本发明涉及显示技术领域,具体涉及一种面板制造方法,以解决显示画面发生牛顿环现象。
 背景技术
在显示器的制造过程中,由于显示器中的塑胶膜材、玻璃基板等构件彼此密合时,产生结构上的弯曲或不平整,会导致构件中膜片的不正常吸附,此为显示器的显示画面上发生牛顿环现象的主要原因之一。
在背光模块与液晶单元贴合前,撕除背光模块上方膜片的保护膜所产生的拉力(离型力),会带起保护膜下的膜片以及膜片下方的胶层,使膜片以及其下方与胶框的框贴面接触的胶层产生些微脱离及拱起,于贴合后会造成背光模块上方膜片的部分区域与液晶单元的下层偏光片吸附,而造成在显示画面上出现有牛顿环现象,严重影响屏幕的光学质量与画面呈现的效果。
防止显示画面出现牛顿环现象的习知手段有通过在膜片彼此密合时，维持两者之间一定的间隙，以解决牛顿环的发生。已有的提案例如于膜片表面进行喷砂处理、使用在膜片的一面或两面进行凹凸处理之薄片等，然而上述手段需通过额外加工或使用额外构件，增加生产成本，因此本发明提出一种从源头防止显示画面出现牛顿环现象的方法。
 技术问题

如图3所示,背光模块20的胶框110的框贴面与其上方的膜片102以胶层104黏固。
本较佳实施例提出的一种用于解决显示器面板上画面出现牛顿环现象的面板制造方法,包括:在背光模块20的胶框110的框贴面上进行粗糙化处理,用于提升所述胶框110的框贴面对其上方的胶层104及胶层104上方的膜片102的固着力;降低背光模块20上方膜片102(例如一增亮膜)上方的保护膜103的离型力,用于降低撕除所述保护膜103时,对其下方的膜片102及膜片102下方的胶层104所产生的拉力;以及在膜片102与背光模块20的胶框110贴合中,延长贴合时间,用于增加所述膜片102与背光模块20的胶框110的框贴面黏合力。
所述粗糙化处理使用电火花加工手段。
所述电火花加工手段以电流1安培的工具电极进行。
所述电火花加工手段将背光模块20的胶框110的框贴面的粗糙度加工至介于1.0-2.5微米(µm)之间。
所述手段增加背光模块20的胶框110的框贴面与胶层104及胶层104上方的膜片102的固着力,使背光模块20的膜片102的保护膜103撕除时的离型力不会将上述背光模块20的胶框110的框贴面上方的胶层104及胶层104上方的膜片102向上拉起。
所述降低背光模块20上的膜片102的保护膜103的离型力手段包括:减小撕除保护膜103的角度、降低撕除保护膜103的速度、以及使用具有较低离型力的保护膜103之至少一种。
所述撕除保护膜103的角度介于1-5度之间。
所述撕除保护膜103的速度介于10毫米/秒-30毫米/秒之间。
所述具有较低离型力的保护膜的离型力介于50-100克之间。
所述贴合介于1.5-3秒之间。
所述贴合的贴合压力介于0.3-0.5百万帕(MPa)之间。
通过实施上述面板制造方法所制造的显示器面板,其背光模块20上的膜片102与液晶单元下的偏光片101的中间部位局部吸附问题的比例由23%降低到0,大幅改善由此吸附问题所产生的显示器面板上画面的牛顿环现象。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
