[0002] Capacitive touch screen technology works by utilizing the human body's current induction. With the rapid development of science and technology, touch screens are used in many fields as a simple and convenient way of human-computer interaction.

[0003] A Chinese patent with announcement number CN209606962U discloses a novel capacitive touch screen, including a touch screen body and a protective outer frame, wherein L-shaped buffer blocks are provided between the four corners of the touch screen body and the protective outer frame.

[0004] Although the above patent uses L-shaped buffer pads at the corners of the touch screen to cooperate with the protective frame to prevent the touch screen from directly contacting the collision surface, absorb the vibration caused by the collision, and prevent damage such as breakage caused by the collision, the impact force on the four corners of the touch screen is relatively large when it falls, and the elasticity of the L-shaped buffer pad is slightly low, and it cannot completely absorb the impact force caused by the fall and collision, which reduces the buffering capacity of the touch screen. Therefore, a new capacitive touch screen is urgently needed to solve these problems. Utility Model Content
