电磁式手写液晶屏是通过电磁笔在操作过程中和屏幕下的天线板产生磁场变化，根据磁场变化大小来确定触屏操作。现有电磁式手写液晶屏中，屏幕组件通常是通过中框1、背板2等构件进行固定并保护，如图1所示，在组装时，天线板等屏幕组件3嵌入中框内并通过背部的背板2固定，当天线板出现异常，需要将整个中框1、背板2进行拆卸，才能进行天线板的更换，该工序必须在无尘车间内完成，更换维修操作繁琐，也容易对屏幕组件造成损坏。The electromagnetic handwriting LCD screen generates a magnetic field change during the operation of the electromagnetic pen and the antenna board under the screen, and the touch screen operation is determined according to the magnitude of the magnetic field change. In the existing electromagnetic handwriting LCD screen, the screen assembly is usually fixed and protected by the middle frame 1, the back plate 2 and other components. As shown in FIG. 1, during assembly, the screen assembly 3 such as the antenna board is embedded in the middle frame and passes The back plate 2 on the back is fixed. When the antenna plate is abnormal, the entire midframe 1 and back plate 2 need to be disassembled to replace the antenna plate. This process must be completed in a dust-free workshop. The replacement and maintenance operations are cumbersome and easy. Damage to screen components.

本发明电磁屏安装固定结构，包括盖体10、屏幕组件20、天线板件30及固定构件40，其中，盖体10为显示器的前盖，盖体10中部具有方形的开口，在盖体10上环绕开口设置侧壁11，侧壁11围闭构成预留空间，供屏幕组件20嵌入，预留空间的大小与屏幕组件20相适应，使得屏幕组件20的边缘侧端都能够与相对应的侧壁11抵顶接触，从而限制屏幕组件20在水平方向自由移动，完成对屏幕组件20的定位，侧壁11形成的预留空间相当于传统的中框结构，能够对屏幕组件20提供固定并起到保护作用。The electromagnetic screen mounting and fixing structure of the present invention includes a cover body 10, a screen assembly 20, an antenna board 30 and a fixing member 40, wherein the cover body 10 is a front cover of a display, the cover body 10 has a square opening in the middle, and the cover body 10 A side wall 11 is provided around the opening, and the side wall 11 encloses to form a reserved space for the screen assembly 20 to embed. The size of the reserved space is adapted to the screen assembly 20, so that the edge side of the screen assembly 20 can correspond to The side wall 11 abuts against contact, thereby restricting the screen assembly 20 from freely moving in the horizontal direction, and completing positioning of the screen assembly 20. The reserved space formed by the side wall 11 is equivalent to the traditional mid-frame structure, and can provide fixation for the screen assembly 20. Play a protective role.
在盖体10上沿着侧壁11的方向间隔排列设置多个限位结构12，限位结构12用于对天线板件30进行定位，具体地，天线板件30层叠固定在屏幕组件20背部，天线板件30的边缘侧端与盖体10上的各限位结构12抵顶接触，从而也限制了天线板件30在水平方向自由移动。限位结构12包括方形侧壁121和设置在方形侧壁121中心的连接螺孔122，限位结构12在上下左右四个方向均有布置，具体数量根据实际情况选择，方形侧壁121顶住天线板件30的边缘侧端，限制天线板件30上下左右四个方向自由移动。A plurality of limiting structures 12 are arranged at intervals on the cover 10 along the direction of the side wall 11. The limiting structures 12 are used for positioning the antenna board 30. Specifically, the antenna boards 30 are stacked and fixed on the back of the screen assembly 20. The edge side end of the antenna plate 30 comes into abutting contact with each of the limiting structures 12 on the cover 10, thereby also restricting the antenna plate 30 from freely moving in the horizontal direction. The limit structure 12 includes a square side wall 121 and a connecting screw hole 122 provided in the center of the square side wall 121. The limit structure 12 is arranged in four directions of up, down, left, and right. The specific number is selected according to the actual situation. The edge side end of the antenna plate 30 restricts the antenna plate 30 from freely moving in four directions of up, down, left, and right.
各限位结构12均位于侧壁11的外侧，并且天线板件30的尺寸大于屏幕组件20的尺寸，从而天线板件30的工作区域比屏幕组件还大，使得天线板件30上的天线能够分布完整，不会受到结构尺寸限制，即使屏幕组件20边缘部分也能具有较好手写性能。传统技术中由于结构设计问题，使得屏幕组件、天线板件都是嵌入在中框内，使得天线板件因尺寸问题工作区域较小，难以达到良好的手写性能。Each limiting structure 12 is located outside the side wall 11, and the size of the antenna plate 30 is larger than the size of the screen assembly 20, so that the working area of the antenna plate 30 is larger than that of the screen assembly, so that the antenna on the antenna plate 30 can The distribution is complete without being limited by the size of the structure, and even the edge part of the screen assembly 20 can have better handwriting performance. In the conventional technology, due to structural design problems, the screen assembly and the antenna board are embedded in the middle frame, so that the antenna board has a small working area due to size problems, and it is difficult to achieve good handwriting performance.
在各限位结构12上可拆卸式连接固定构件40，固定构件40扣压在天线板件30背部，从而对天线板件30固定安装，进而将屏幕组件20固定，天线板件30本身由玻璃纤维材料构成，结构强度高，通过对天线板件30进行加厚处理，能够将屏幕组件20固定在盖体10的预留空间内，其具体厚度大小根据实际情况选择。The fixing member 40 is detachably connected to each limit structure 12, and the fixing member 40 is buckled on the back of the antenna board 30 to fix and install the antenna board 30, thereby fixing the screen assembly 20, and the antenna board 30 itself is made of glass fiber The material composition and the structural strength are high. By thickening the antenna plate 30, the screen assembly 20 can be fixed in the reserved space of the cover body 10. The specific thickness of the screen assembly 20 is selected according to the actual situation.
其中，各固定构件40包括弯折相连形成一体的固定板41和压板42，固定板41嵌入在方形侧壁121内部并通过螺丝43固定，压板42跨过方形侧壁121伸出扣压在天线板件30边缘侧端的背部，通过天线板件30边缘侧端上的各压板42，有效地将天线板件30锁定；而且，通过压板42扣压结构设计，能够避免由于螺丝锁固的力度不同，造成固定空间有所差异。Each fixing member 40 includes a fixing plate 41 and a pressing plate 42 that are bent and connected to form an integrated body. The fixing plate 41 is embedded in the square side wall 121 and fixed by screws 43. The pressing plate 42 extends across the square side wall 121 and is pressed onto the antenna plate The back part of the edge side end of the piece 30 is effectively locked by the pressing plates 42 on the edge side end of the antenna plate piece 30; The fixed space varies.
本发明电磁式手写液晶显示器，包括前述的电磁屏安装固定结构，通过该种安装固定结构，能够有效地简化安装及拆卸过程。The electromagnetic handwriting liquid crystal display of the present invention includes the aforementioned electromagnetic screen mounting and fixing structure, and through this mounting and fixing structure, the process of installation and disassembly can be effectively simplified.
