[0001] The utility model relates to the field of digital screens, in particular to a digital screen with touch bridge control. Background Art

[0002] LED digital screen is a commonly used display device in household appliances, which can display various states or functions of the equipment. The existing touch-controlled LED digital screen generally adopts touch spring or touch membrane, but in actual use, using only one of them will have certain disadvantages; specifically, 1. If only touch spring is used, when the diameter of the spring implanted in the shell is too small, it will block the light of the LED, so that a shadow will appear on the display membrane of the LED digital screen. When the diameter of the spring implanted in the shell is too large, it will exceed the diameter of a human finger, so it is difficult to sense the charge information of the human hand, resulting in low touch sensitivity; 2. If only touch membrane is used, since the touch signal must have a gold finger at the end of the membrane with a printed circuit, which is bent and connected to the socket at the PCB under the digital screen for connection, when the outer band is bent for a long time, it is easy to break the circuit, resulting in an open circuit phenomenon, which has certain quality risks, and the production cost of the gold finger at the end of the touch membrane is also relatively high; therefore, there is an urgent need for a digital screen with touch bridge control to solve the above problems.
