Design Of Output Single Circuit Of Embedded Monochrome Touch Screen

Capacitive touch screen in the industrial control application is on the Display with LCD(Liquid Crystal Display)is developed with the development of the has the advantages of light,energy saving,has become a Display one of the most rapidly growing Display device in the family.Now with liquid crystal display manufacturing technology and the rapid development of integrated circuits,industrial control equipment control after a key control mode,control and display separation model,the case capacitive touch display mode,the embedded capacitive touch control mode in several stages of development.Capacitive touch display now in home appliances,industrial instrumentation,medical electronic products,the commercial electronic products and them is finding wider and wider application in the field of electronic products.Based on twisted nematic and super twisted nematic materials within embedded capacitive touch display the output signal of circuit design project,design and making the same first touch and display function of traditional CTP capacitive touch screen LCD display module,designs the corresponding touch signal output circuit and display signal output circuit,and write the corresponding quantum two driver circuit,on the basis of success make traditional CTP LCD module,embedded capacitive touch display in research and development;Then the design of an embedded LCD display output signal wiring design,touch key signal output layout design as well as the two fusion after chrome version of the design and development;Finally,the output signal circuit principle diagram design,flexible circuit board design,printed circuit board design,the circuit driver programming design,Touch and Icon functional debugging and testing,etc.Embedded within the monochrome touch screen output signal circuit design includes: the composite signal embedded capacitive touch display with touch control circuit design,embedded capacitive touch display output signal in the flexible circuit design,embedded within a capacitive touch display output signal adjustment circuit design,backlit platen PCB circuit design,etc.The corresponding software design: embedded touch screen capacitive touch threshold in software testing platform,the embedded capacitive touch display signal output debugging program design,etc.To meet the needs of samples of all kinds of practical application,the sample circuit board performance test system is established,the touch sensitivity performance debugging,testing,capacitive touch channel threshold voltage test and reliability test,to verify the touch and show the test effect,thus ensuring experimental products meet the actual production,the feasibility of design and manufacturing process.Through the tests,experimental results are in accordance with the design thought.
