Device and method for welding electronic component and method for manufacturing display

The invention provides a device for welding electronic components. The device comprises a bearing platform, an abutting element, a closed space generating mechanism, an air exhaust mechanism and an energy generating mechanism. The bearing platform is used for bearing a substrate. The pressing element is made of a flexible material. The closed space generating mechanism can place the abutting element on the bearing platform, so that a closed space is formed between the abutting element and the bearing platform. The air exhaust mechanism is used for exhausting air in the closed space. The energy generating mechanism is arranged adjacent to the bearing platform and can generate energy on the bearing platform. A method of welding an electronic component and a method of manufacturing a light emitting diode display are also provided. 本发明提供一种用以焊接电子元件的装置，其包括承载平台、抵压元件、密闭空间产生机构、抽气机构及能量产生机构。承载平台用以承载基板。抵压元件为挠性材质者。密闭空间产生机构可将抵压元件置放于承载平台上，而使抵压元件和承载平台间形成密闭空间。抽气机构用以对密闭空间抽气。能量产生机构设置于邻近承载平台处，并可于承载平台上产生能量。一种焊接电子元件的方法及制造发光二极管显示器的
