Patent number: 11205549Abstract: A keycap structure includes a keycap body and a display module. The keycap body includes a top wall and a lateral wall. The lateral wall is extended downwardly from a periphery region of the top wall. An accommodation space is defined by the top wall and the lateral wall collaboratively. The display module is disposed within the accommodation space. The display module includes a light-transmissible circuit substrate and plural light-emitting elements. The plural light-emitting elements are installed on the light-transmissible circuit substrate and electrically connected with the light-transmissible circuit substrate. After the light beams are transmitted through the light-transmissible circuit substrate and the top wall sequentially, the light beams are outputted from the keycap body. The light beams from the plural light-emitting elements are collaboratively formed as a luminous zone. Moreover, a pattern corresponding to the luminous zone is shown on the display module.Type: GrantFiled: February 2, 2021Date of Patent: December 21, 2021Assignee: PRIMAX ELECTRONICS LTD.Inventors: Bo-An Chen, Chin-Sung Pan, Ya-Chin Tu
