Description

CROSS-REFERENCE TO RELATED APPLICATIONS This non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 113111475 filed in Republic of China (ROC) on Mar. 27, 2024, the entire contents of which are hereby incorporated by reference. BACKGROUND 1. Technical Field This disclosure relates to a display. 2. Related Art Traditionally, when purchasing a display, user is limited to the original display size and is allowed only one display size. In scenarios where multiple display requirements exist, users need to purchase one or more displays of different sizes to meet various usage needs. For example, to satisfy multimedia need, the user must purchase a large-sized, high-resolution display with a standard refresh rate; to meet gaming need, the user need to purchase a small-sized, low-resolution display with a high refresh rate. Although current gaming displays provide a “Display Mode” feature that allows the user to adjust the display size, achieving the desired size still requires multiple steps for adjustment, making it difficult to switch quickly between different scenarios. SUMMARY Accordingly, this disclosure provides a display. According to one or more embodiment of this disclosure, a display includes: a memory, a physical switching element and a controller. The memory is configured to store a plurality of pieces of candidate extended display identification data. The physical switching element is configured to be triggered by external force to generate a first switching signal. The controller is connected to the memory and the physical switching element, the controller is configured to control a displayed screen according to original setting data among the plurality of pieces of candidate extended display identification data, and adjust the displayed screen according to target data that is different from the original setting data among the plurality of pieces of candidate extended display identification data after receiving the first switching signal. In view of the above description, the display according to one or more embodiments of the present disclosure, through the physical switching element, user may switch the display's resolution and screen size with a single button, achieving multifunctionality with a single device. Further, the user is also allowed to focus the screen more within the range of their visual focus. Therefore, when the display is used for gaming, players may gain an advantage in spotting enemies more effectively.
