本发明涉及触摸屏领域。The invention relates to the field of touch screens.
背景技术Background technique
随着触摸屏OGS技术趋于成熟稳定，已不能完全满足市场需求，将相对定位于中低档的中大尺寸电容式触摸屏市场。现有技术中的触摸屏，无反馈效果，在汽车行驶过程中触控存在安全隐患。然而目前也有通过震动反馈接触信号，但传统震动反馈不是单点反馈，不能通过震动点确定触摸位置。As the touch screen OGS technology becomes mature and stable, it can no longer fully meet the market demand, and will be relatively positioned in the middle and low-end medium and large size capacitive touch screen market. The touch screen in the prior art has no feedback effect, and there is a potential safety hazard in the touch screen during the driving of the car. However, there is also a contact signal via vibration feedback at present, but the traditional vibration feedback is not a single-point feedback, and the touch position cannot be determined through the vibration point.

具体实施方式Detailed ways
下面对照附图，通过对实施例的描述，本发明的具体实施方式如所涉及的各构件的形状、构造、各部分之间的相互位置及连接关系、各部分的作用及工作原理、制造工艺及操作使用方法等，作进一步详细的说明，以帮助本领域技术人员对本发明的发明构思、技术方案有更完整、准确和深入的理解。Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.
如图1所示，触觉反馈触摸屏依次设有以下层结构，包括：A面保护膜、HC层、AIM+ITO层、玻璃层、BM层、BIM+ITO层、PI层、Metal线层、OC层和B面保护膜。As shown in Figure 1, the tactile feedback touch screen has the following layer structure in sequence, including: A-side protective film, HC layer, AIM+ITO layer, glass layer, BM layer, BIM+ITO layer, PI layer, Metal wire layer, OC Layer and B-side protective film.
A面IM+ITO(AIM+ITO层)位于玻璃层浮法面，HC层位于AIM+ITO层外侧位置。玻璃层为AG处理后的玻璃，AG处理在浮法面且玻璃厚度为0.4mm。那么AIM+ITO pattern镀膜蚀刻在AG面，ITO pattern为常规的菱形且菱形网格0.68mm*0.45mm。The A-side IM+ITO (AIM+ITO layer) is located on the float surface of the glass layer, and the HC layer is located outside the AIM+ITO layer. The glass layer is glass after AG treatment, and the AG treatment is on the float surface and the glass thickness is 0.4mm. Then the AIM+ITO pattern coating is etched on the AG surface, the ITO pattern is a conventional diamond and the diamond grid is 0.68mm*0.45mm.
BM层位于玻璃空气面，B面IM+ITO(BIM+ITO)位于BM外侧位置，PI层位于BIM+ITO外侧位置，Metal线位于PI层外侧位置，OC层位于Metal线外侧位置。The BM layer is located on the glass air surface, the B-side IM+ITO (BIM+ITO) is located outside the BM, the PI layer is located outside the BIM+ITO, the Metal line is located outside the PI layer, and the OC layer is located outside the Metal line.
HC层位于AIM+ITO外侧位置。其中HC层采用镀膜方式处理，由SiO2、Nb2O5、TiO2和SiNX单一成分或多个成分组成，起到保护A面ITO pattern作用。The HC layer is located outside the AIM+ITO. Among them, the HC layer is treated by coating, which is composed of SiO2 , Nb2 O5 , TiO2 and SiNX single or multiple components, which can protect the ITO pattern on the A surface.
BIM+ITO层与AIM+ITO层相同，只是方阻比AIM+ITO方阻小，保证其在安全电流范围内。可根据具体的要求更改相应阻值。本实施方式以AIM+ITO方阻为BIM+ITO方阻的2倍实施。Metal线层采用阻值较小的MAM，Cu等合金制成。The BIM+ITO layer is the same as the AIM+ITO layer, but the square resistance is smaller than the AIM+ITO square resistance, ensuring that it is within the safe current range. The corresponding resistance value can be changed according to specific requirements. In this implementation mode, the square resistance of AIM+ITO is twice that of BIM+ITO. The Metal wire layer is made of alloys such as MAM and Cu with low resistance.
如图2所示，通过感知不同电流确认触摸位置，于B面触摸位置通过电磁作用传递到A面，达到触觉反馈效果。As shown in Figure 2, the touch position is confirmed by sensing different currents, and the touch position on the B side is transmitted to the A side through electromagnetic action to achieve the tactile feedback effect.
反馈效果的原理：B面pattern与处理芯片(IC)相连，通电作用下显示图案和产生电流，根据电磁互生原理，在pattern线路会产生相应的旋转磁场。B面磁场作用在A面pattern产生电流，在手指接触A面，人体与A面pattern形成回路，电流刺激手指，产生触觉反馈作用。The principle of the feedback effect: the pattern on the B side is connected to the processing chip (IC), and the pattern is displayed and the current is generated under the action of electricity. According to the principle of electromagnetic interaction, a corresponding rotating magnetic field will be generated in the pattern circuit. The magnetic field on surface B acts on the pattern on surface A to generate a current. When the finger touches surface A, the human body and the pattern on surface A form a loop, and the current stimulates the finger to produce tactile feedback.
