Embedded touch display device with antenna module

technical field

This case relates to a touch display device, in particular to an embedded touch display device with an antenna module.

Background technique

With the advancement of information and communication technology, electronic devices with touch functions such as mobile phones, tablet computers, and portable computers have become indispensable equipment in people's daily life. Generally speaking, an electronic device with touch function needs to include a touch display device, wherein the touch display device includes a glass cover, a touch module and a display module. The touch module is arranged under the glass cover, and the touch module and the display module are directly stacked up and down. Because the touch module is a transparent panel, the image can be displayed through the touch module stacked on it. Then use the touch module as an input medium or interface. However, electronic devices are gradually developing towards thinner and higher density. Traditional touch display devices must add a touch module, which greatly increases the weight of touch display devices, which is not in line with the current market demand for light and thin displays. , Short, and small requirements, and directly stacking the touch module will increase the thickness, thereby reducing the light penetration rate, increasing the reflectivity, color shift and haze, and reducing the quality of the screen display. In addition, the traditional touch module and its configuration will increase the process steps and material costs, and will affect the touch sensing effect of the touch panel and the visual effect of the display module.

Touch display technology on the market today can be simply divided into external touch technology and embedded touch technology according to the setting position of the touch module. The embedded touch technology has the advantages of thinner overall thickness, simplified process, and can maintain Due to the original color rendering and brightness of the display, the embedded touch technology has become the focus of research and development. However, the touch electrodes used in the current in-cell touch technology are mainly transparent electrodes of indium tin oxide (hereinafter referred to as ITO). For large size and flexible display applications. In addition, the sensing electrode layer of the traditional in-cell touch technology is closer to the driving circuit of the display module, which tends to introduce more noise. Furthermore, the traditional in-cell touch technology needs to add multiple processes in the process steps of the display module to form an in-cell touch structure, which will reduce the output of the display, prolong the production cycle, and increase the overall production cost. And it is not easy to customize, it is not easy to add added value, and it is impossible to improve reliability and yield. In addition, return to the technology itself: First, the introduction of traditional in-cell touch technology is estimated to cause panel manufacturers to suffer a yield loss ranging from 3% to 10% before mass production, which will result in predictable processes and materials. Cost loss, so yield improvement is bound to be an important task; moreover, for In-cell TDM, which has the highest content of embedded touch technology, the touch and display layers share a high degree of circuit layout. Once the panel resolution changes from the current HD/ Upgrading from FHD to WQHD/UHD, not to mention the challenge of production yield, the trade-off between pixel aperture ratio (Aperture Ratio) and charging rate (Charging Ratio), time-sharing processing of display driving and touch detection ( Timing Control) and other mechanisms, as well as the electromagnetic field noise interference inside the panel, etc., are all levels to be solved. Finally, the touch layer of the in-cell touch panel highly relies on the change of the electromagnetic field (capacitance change) to detect the touch event. When the glass plate is removed and the structure is simplified, the emitter electrode (Tx) and the sense electrode (Rx) are easily The loss of touch function due to external electrostatic damage is usually solved by antistatic polarizers or conductive silver glue in the industry. In the future, with the evolution of products in large size, borderless, high resolution, etc., other solutions need to be proposed. Optimize the design to increase product reliability. Therefore, it is necessary to develop an embedded metal grid touch display device to solve the problems faced by the prior art.

On the other hand, with the advancement of information and communication technology, electronic devices combined with wireless communication functions have become indispensable equipment in people's daily life. Generally speaking, an electronic device with wireless communication function needs to include an antenna module and a wireless signal processing module. surface, the inner surface of the back cover, or the bottom side of the display panel. However, electronic devices are gradually developing towards thinner and higher density. The traditional antenna module and its setting method need to reserve a clear area to avoid signal interference, so it will occupy the space inside the electronic device, affect the internal circuit layout, and make the electronic device The thickness cannot be reduced further. Taking a touch display device combined with a wireless communication function as an example, when the traditional antenna module and setting method are introduced into the touch display device, the process steps and material costs will be increased, and it is easy to cause signal interference, which will affect the effect of wireless signal transmission and reception of the antenna module. The touch sensing effect of the touch module.

In addition, the feeder included in the antenna module usually uses an external cylindrical cable, wherein the cylindrical cable includes a core, an insulating layer covering the core, a metal shield covering the insulating layer, and a A protective layer over a metal shield. However, although the cylindrical cable can avoid the signal interference of the feeder, its thickness is thick and difficult to bend, and additional process steps are required to connect the antenna radiator to the feeder, which is not conducive to the integration and development of the antenna module and touch technology .
