Title: TOUCH SCREEN AND DISPLAY
Abstract:
A touch screen and a display. The display comprises a housing and a touch screen, the touch screen being assembled inside the housing. The touch screen comprises a shell (10), a filter strip (13), a writing panel (14), and a touch circuit board (12); the touch circuit board (12) comprises a main body (121) and an IR module (11) provided on the main body (121); an accommodating cavity (16) for accommodating the touch circuit board (12) is provided on the shell (10); the IR module (11) is close to or abuts against the inner surface of the writing panel (14), such that the distance from a central axis (111) of the IR module (11) to the writing panel (14) is effectively reduced, i.e., the distance from an infrared matrix formed by the IR module (11) to the writing panel (14) is reduced, and thus the recognition precision and sensitivity of the touch screen are improved and user experience is enhanced.
