现有手机显示面板一般为2D玻璃，即平面玻璃结构。但随着用户需求的拓展，手机显示面板逐渐转向2.5D玻璃(2D玻璃的一条边热压压弯形成曲边结构)和3D玻璃((2D玻璃的两条至四条边热压压弯形成多条曲边结构)。无论是2D、2.5D还是3D玻璃手机显示面板，都会涉及在显示面板的边框区设置有颜色的油墨层用于遮蔽内部电路结构。因此，设置的有颜色的油墨层仅设置在边框区，边框区内部形成视窗区，且边框区中的IR孔(用于感应人脸贴合便锁屏进而防止脸部对显示面板的误操作)和前置摄像孔处不设置有颜色的油墨。也就是说，无论对哪种形状的显示面板来说，都需要在显示面板的表面形成包括视窗区、摄像孔和IR孔的无油墨空白图案。但现有的在显示面板上设置有颜色的油墨层的方式为丝印和/或移印，因受网版张力和/或3D玻璃弧面高度影响，且所述空白图案均会部分设置在3D弧面上或其边缘很接近3D弧面，因而油墨层的该设置方式仅适应于加工2D或2.5D玻璃，用该方法加工3D玻璃时极易出现油墨回油、孔内牙缺、压边、油墨印刷不均等不良情况。The existing mobile phone display panel is generally 2D glass, that is, a flat glass structure. However, with the expansion of user demand, mobile phone display panels are gradually turning to 2.5D glass (one side of 2D glass is hot-pressed to form curved edge structure) and 3D glass ((two to four sides of 2D glass are formed by hot pressing) Strip edge structure). Whether it is 2D, 2.5D or 3D glass phone display panel, it will involve setting a color ink layer in the frame area of the display panel to shield the internal circuit structure. Therefore, the color ink layer is only set. Set in the frame area, the window area is formed inside the frame area, and the IR hole in the frame area (used to sense the face fit and lock screen to prevent the face from misoperation of the display panel) and the front camera hole are not provided Color ink. That is to say, regardless of the shape of the display panel, it is necessary to form an ink-free blank pattern including a window area, a camera hole and an IR hole on the surface of the display panel. However, the existing one on the display panel The manner in which the colored ink layer is provided is silk screen printing and/or pad printing, which is affected by the screen tension and/or the 3D glass arc surface height, and the blank patterns are partially disposed on the 3D arc surface or the edges thereof are very close. 3D curved surface, Therefore, the arrangement of the ink layer is only suitable for processing 2D or 2.5D glass. When the 3D glass is processed by the method, the ink returning oil, the missing teeth in the hole, the edge pressing, the uneven printing of the ink, and the like are extremely likely to occur.
因此，本领域有必要提供一种新的在3D玻璃上设置有颜色的油墨层的方法，具体是一种3D玻璃的表面空白图案的加工方法。Therefore, it is necessary in the art to provide a new method for providing a color ink layer on a 3D glass, in particular, a method for processing a surface blank pattern of a 3D glass.

Ink (such as white oil) is filtered by 400 mesh mesh. The thickness of the sprayed film is controlled at 8-11um. After spraying, it is baked at a temperature of 90 °C. The baking time is controlled at 8min. The light source needs to use yellow light;
2)将喷涂烘烤干后的产品用特制3D光罩，(需得到空白图案的区域大小/位置均体现在此3D光罩片上，需得到空白图案对应在光罩上的区域呈不透光的黑色，光罩上其它区域呈透明的玻璃本色)置于产品上端，并与产品紧密贴合进行遮蔽，再把其置于曝光机中进行曝光，将平行光曝光机能量调至500mj进行曝光，因考虑各油墨颜色对光波长的反应，曝光机中LED灯光源波长含有365nm/385nm/395nm三种波长，且曝光机灯源需是平行光；2) The special 3D mask will be sprayed and dried. (The size/position of the area where the blank pattern is to be obtained is reflected on the 3D mask sheet, and the blank pattern is required to be opaque to the area on the mask. The black color, the transparent glass on the other part of the mask is placed on the upper end of the product, and it is closely attached to the product to cover it. Then it is placed in the exposure machine for exposure, and the energy of the parallel light exposure machine is adjusted to 500mj for exposure. Considering the reaction of each ink color to the wavelength of light, the wavelength of the LED light source in the exposure machine contains three wavelengths of 365 nm/385 nm/395 nm, and the source of the exposure machine needs to be parallel light;
3)将整面喷涂好油墨并已曝光的3D玻璃产品放置于显影机台上，使用质量比碳酸钠：水＝0.01:100或氢氧化钠：碳酸钠：水＝0.005:0.005:100进行配比得到显影液，或者直接商购碱性显影液，让产品经过带有显影液的平板清洗机，显影槽时间控制在25-60s，水压力0.5±0.1kg/CM2，然后分别再过溢流水槽-风切，溢流水槽时间120-150s，水压力2.5±1kg/CM2；溢流水压力2±0.3kg/CM2，显影液配比为碳酸钠：水＝1％：100％，当3D玻璃产品经过显影槽后，被平行光照射的区域的油墨被保留下来，被光罩遮蔽的区域的油墨被显影液腐蚀掉，再将产品加烤固化即可。3) Place the whole surface of the ink and expose the exposed 3D glass product on the developing machine, and use the mass ratio of sodium carbonate: water=0.01:100 or sodium hydroxide: sodium carbonate: water=0.005:0.005:100. Compared with obtaining the developer, or directly purchasing the alkaline developer, let the product pass through the flat washer with the developer, the development tank time is controlled at 25-60 s, the water pressure is 0.5±0.1 kg/CM 2 , and then overflows respectively. Flow tank - wind cut, overflow tank time 120-150s, water pressure 2.5 ± 1kg / CM 2 ; overflow water pressure 2 ± 0.3kg / CM 2 , developer ratio is sodium carbonate: water = 1%: 100%, When the 3D glass product passes through the developing tank, the ink in the area illuminated by the parallel light is retained, and the ink in the area covered by the reticle is etched away by the developing solution, and then the product is baked and solidified.
4)考虑喷涂后杂质点/灰尘对曝光的影响，在显影后形成沙眼不良，可通过两喷涂两烤两次曝光解决沙眼不良。4) Considering the influence of impurity spots/dust on the exposure after spraying, the formation of trachoma after development is poor, and the trachoma defect can be solved by two spraying and two baking exposures.
按照该方法，可成功在3D玻璃上精准地实现视窗区、IR孔、摄像孔等表面空白图案。According to this method, surface blank patterns such as window areas, IR holes, and image holes can be accurately realized on the 3D glass.
