Common problems and solutions of LCD segment code

by:Genyu     2020-02-18

with the development of technology, the popularity of LCD segment code LCD screen, in addition to giving us a lot of convenience, we will also encounter a series of problems, hinder the user's experience, the following is a summary of some problems and solutions. Question 1. Touch sliding inflexible fault one: touch deviation phenomenon: the position touched by the finger does not coincide with the mouse arrow. Analysis: After installing the driver, when correcting the position, there is no vertical touch of the center of the bull's eye. Processing Method: re-correct the position. Fault 2: touch deviation phenomenon: Some areas are touched accurately, and some areas are touched with deviation. Analysis: a large amount of dust or scale has accumulated on the acoustic reflection stripes around the LCD screen, which affects the transmission of acoustic signals. Processing Method: Clean the LCD segment code LCD screen, pay special attention to clean the sound wave reflection stripes on the four sides of the LCD segment code LCD screen, and disconnect the power supply of the LCD segment code LCD screen control card during cleaning. Fault 3: No response to touch: the mouse arrow does not move when the LCD segment code LCD screen does not change its position. Analysis: There are many reasons for this phenomenon, which are explained one by one below :(1) Surface acoustic wave LCD segment code the accumulated dust or scale on the acoustic wave reflection stripes around the LCD screen is very serious, causing the LCD segment code LCD screen to fail to work. (2)LCD segment code the LCD screen has failed. (3)LCD segment code the LCD control card has failed. (4)LCD segment code LCD signal line failure. (5)The serial port of the host computer has failed. (6)The computer's operating system has failed. (7) LCD segment code LCD driver installation error. Second, the resistance LCD segment code LCD screen fault phenomenon analysis and processing method fault 1: touch deviation phenomenon: the position touched by the finger does not coincide with the mouse arrow. Analysis: After installing the driver, the center position of the bull's eye was not touched vertically when correcting the position. LCD segment code the signal line on the LCD screen is in poor contact or is open. Processing Method: re-correct the position; Find breakpoints reconnect or replace the LCD segment code LCD. Fault 2: touch deviation phenomenon: the mouse arrow always stays at a certain position when not touching, and the mouse arrow is at the midpoint between the touch point and the original stop point when touching. Analysis: There is a foreign body (Non-active touch) The compression resistor LCD segment code is in the effective working area of the LCD screen. Processing Method: remove the foreign matter in the effective working area of the compression resistor LCD segment code LCD screen. Fault 3: No response to touch: the mouse arrow does not move when the LCD segment code LCD screen does not change its position. Analysis: many reasons for this phenomenon are explained one by one below :(1)LCD segment code the LCD screen fails (2)LCD segment code the LCD control card has failed. (3)LCD segment code LCD signal line failure. (4)The serial port of the host computer has failed. (5)The computer's operating system has failed. (6) LCD segment code LCD driver installation error.
