Technical Q&A
Q: When the capacitive screen module is lightening, white spots, bright spots, dirty spots can be seen in the backlight, what is the reason? How to avoid it?
A: White spots and highlights are generally caused by impurities entering or damage to the backlight material. If there is impurity entering, what should be done is to trace the impurities from the LCM itself and find out where it comes from, and focus on the clean room assembly environment; if the backlight is damaged, it should be considered from the LCM structure, especially the product structure to find out what area of the structure poses a risk of injury or scratching to the LCM, and then eliminates it
Q: What is the principle of capacitive touch screen to achieve multi-touch?
A: When the finger touches the capacitive screen, it affects the coupling between the two electrodes near the touch point, thus changing the capacitance between the two electrodes. When detecting the mutual capacitance, the lateral electrodes sequentially emit excitation pulse signals, and all the longitudinal electrodes receive signals at the same time, so that the capacitance values of all the intersections of the lateral and longitudinal electrodes can be obtained, that is, the capacitance of the two-dimensional plane of the entire touch screen. According to the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated. That is, the real multi-point coordinates can be calculated to realize multi-touch;
