Abstract

The invention relates to an LCD (Liquid Crystal Display) touch-controlled all-in-one machine which comprises a liquid crystal box, an upper polarizer and a lower polarizer, wherein a touch screen induction electrode is arranged on the upper surface of the liquid crystal box, the upper polarizer is arranged on the upper surface of the touch screen induction electrode, the liquid crystal box is internally provided with a first LCD electrode an a second LCD electrode, and the lower polarizer is arranged on the lower surface of the liquid crystal box. A manufacturing method of the LCD touch-controlled all-in-one machine comprises 11 steps. An additional touch screen is saved in the LCD display touch-controlled all-in-one machine, so that the cost is greatly reduced, the thickness of the entire LCD display touch-controlled all-in-one machine is reduced by 1.3mm at the same time, and meanwhile, the phenomenon of Newton 's rings caused by design defects or assembling defects of the touch screen can be effectively avoided. A layer of glass is eliminated, so that LCD display touch-controlled all-in-one machine can also solve the problem of the light transmittance loss, and avoid the brightness loss without enhancing the backlight brightness so as to well save the electric energy. An IC (Integrated Circuit) is not required to be controlled by a special SCT (Surface Charge Transistor) and keying signals can be directly read by a single chip microcomputer, so that the instable situations caused by compatibility can be avoided.

Description

technical field [0001] The invention relates to an LCD display and touch integrated machine and a manufacturing method thereof. Background technique [0002] At present, in the fields of industrial instruments, medical equipment, and home appliances, simple human-computer interaction is required in many occasions. Compared with the method of connecting external buttons, using a touch screen on the LCD is equivalent to superimposing the buttons on the display, which can reduce the size of the LCD and obtain a better human-computer interaction experience. [0003] Such as figure 1 As shown, the button touch function of the traditional industrial control liquid crystal display is realized by adding a resistive or capacitive touch screen on the liquid crystal screen of the liquid crystal display. LCD display electrode 8' and two pieces of ITO glass containing alignment layer and liquid crystal form a liquid crystal cell 5', and then attach a polarizer 3' on the upper surface o...
