Écran capacitive projeté .can be divided into two types: self-capacitance screen and mutual-capacitance screen. The more common mutual-capacitance screen is an example. The interior is composed of driving electrodes and receiving electrodes. The driving electrodes emit low-voltage and high-frequency signals and project them to the receiving electrodes to form a stable Electric current, when the human body touches theÉcran capacitif ., bawo hadamaden farikolo bɛ duguma , bolokɔni ni .Écran capacitif .Aw bɛ se ka kɛ ni ɲɔgɔndan ye, ani taamasiyɛn minnu ka bon kosɛbɛ, olu bɛ se ka woyo ka don dugukolo kɔnɔ ni nin danfaralan ye, walasa charge hakɛ min bɛ sɔrɔ jaabi laban na, o ka dɔgɔya ni bolokɔnincinin surunyara transmetting terminal la, kuran charge bɛ dɔgɔya ka ɲɛ. laban na, magan yɔrɔ bɛ latigɛ ka kɛɲɛ ni sisan fanga ye min bɛ sɔrɔ jaabi laban na.
The horizontal and vertical electrode arrays are made of ITO on the glass surface. These horizontal and vertical electrodes respectively form a capacitance with the ground. This capacitance is commonly referred to as self-capacitance, which is the capacitance of the electrode to the ground. When the finger touches the capacitive screen, the capacitance of the finger will be superimposed on the capacitance of the screen, which increases Écran ka capacitance.
In the touch detection, the self-capacitance screen detects the horizontal and vertical electrode arrays respectively, and determines the horizontal and vertical coordinates according to the changes in capacitance before and after the touch, and then combines them into planar touch coordinates. The self-capacitance scanning method is equivalent to projecting the touch points on the touch screen to the X-axis and Y-axis directions respectively, and then calculate the coordinates in the X-axis and Y-axis directions kelen-kelen, ka laban k’u fara ɲɔgɔn kan ka kɛ touch point. coordinates ye.

According to the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated. Therefore, even if there are multiple touch points on the screen, the true coordinates of each touch point can be calculated.
The advantage of the mutual capacitance screen is that there is less wiring, and it can identify and distinguish the difference between multiple contacts at the same time. The self-capacitance screen can also sense multiple contacts, but because the signal itself is blurred, it cannot be distinguished. In addition, the sensing scheme of the mutual capacitance screen has the advantages of fast speed and low power consumption, because it can measure all nodes on a drive line at the same time, O la a bɛ se ka dɔ bɔ sɔrɔ sɛgɛsɛgɛli hakɛ la ni 50%. ye nin kuran fila jɔcogo in na, kɛnɛma mankan yɛrɛ-yɛrɛyɛrɛ baara bɛ a la ani a bɛ se ka taamasiyɛn sabatili ɲɛ fanga hakɛ dɔ la.
