Touch display screen with clear touch feedback

Abstract

The invention relates to the technical field of touch display screens, in particular to a touch display screen with clear touch feedback. The touch display screen comprises a terminal housing, whereina downwards-concave installation inner cavity is formed in the middle of the upper end face of the terminal housing; a backboard is arranged on the lower end surface of the terminal housing; and an excitation circuit board, a main control circuit board and a touch display screen are sequentially arranged in the mounting inner cavity from bottom to top. The touch display screen has the beneficialeffects that: an excitation circuit is arranged at the lower end of a main circuit board, the excitation circuit is used for driving an excitation block to vibrate, so that vibration is transmitted toan extension plate with the cooperation of conduction of a conduction rod, vibration of the extension plate drives a spring poking piece to vibrate, then an insertion column at a touch position is driven to rotate, the touch position is clearly known, and high touch feedback is achieved; and by arranging the spring poking piece, the insertion column is rapidly restored after vibration, so that feedback timeliness is achieved, mutual interference between multiple times of touch control is avoided, the feeling of a handheld terminal backboard is improved by using bosses, and therefore the vibration effect is amplified.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen with clear tactile feedback. Background technique [0002] Touch screen (Touch Panel), also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. The tactile feedback system can drive various connecting devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio-visual effects through the liquid crystal display screen. [1] [0003] As the latest computer input device, the touch screen is a simple, convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. Mainly used in public information query, industrial control, military command, electronic games, multimedia teaching, etc. [0004] The surface of the existin...

AI Technical Summary

Problems solved by technology

[0004] The surface of the existing touch screen is relatively smooth, especially when the smooth tempered film is attached to protect its outer wall, the touch feeling of the finger is low when touching the display screen, and it is difficult to clearly feel the touch effect, which in turn causes accidental touches and other situations. There are technical settings to remind through vibration. However, a large vibration will cause the overall vibration of the fuselage, and it is impossible to understand the position of the touch. A small vibration will cause a small feeling and no feedback effect.

[0005] Therefore, a touch display with clear tactile feedback is provided to solve the problem of tactile feedback of the touch display
