Description

電子裝置Electronic device

本揭示是關於一種具有觸控板的電子裝置。The present disclosure relates to an electronic device with a touch panel.

市面上有部分款式的筆記型電腦的觸控板具備數字鍵的功能，此類觸控板的蓋板具有數字、符號等圖案作為按鍵。觸控板的蓋板大多以膠水固定，膠水塗佈於蓋板內側，使蓋板能黏貼於下方元件上。為了提高透光度，蓋板上對應數字、符號等圖案的部分不塗佈膠水。然而，不塗佈膠水處的空隙包含空氣，可能因溫度變化等因素而與外界壓力不平衡，進而導致蓋板變形(例如：使蓋板內凹或外凸)，影響產品外觀。There are some styles of notebook computers on the market that have touchpads with numeric keys. The cover of this type of touchpad has patterns such as numbers and symbols as buttons. The cover of the touch panel is mostly fixed with glue, and the glue is coated on the inner side of the cover so that the cover can be stuck to the lower component. In order to improve the light transmittance, no glue is applied to the part of the cover plate corresponding to the patterns such as numbers and symbols. However, the gap where glue is not applied contains air, which may be unbalanced with external pressure due to temperature changes and other factors, which may cause deformation of the cover (for example, make the cover concave or convex) and affect the appearance of the product.
