顯示模組 Display module

本發明關於一種顯示模組。 The invention relates to a display module.

目前的電子裝置例如平板電腦通常具有金屬外殼,故當天線結構設於背側時,需將金屬外殼對應天線結構的部分形成多個開孔或採用非屏蔽材質以解決信號屏蔽問題。然而,此一設計容易破壞電子裝置的整體外觀及強度,且於製造時通常需搭配額外的模內射出或其他的組裝程序,提高製程的難度。 Current electronic devices, such as tablet computers, usually have a metal casing. Therefore, when the antenna structure is disposed on the back side, a portion of the metal casing corresponding to the antenna structure is required to form a plurality of openings or an unshielded material to solve the signal shielding problem. However, this design is likely to damage the overall appearance and strength of the electronic device, and is usually required to be combined with additional in-mold injection or other assembly procedures to improve the difficulty of the process.
