The essence of the touch screen is a sensor. At present, according to the type of sensor, the touch screen is roughly divided into four types: infrared type, resistance type, surface acoustic wave type and capacitive type.

The infrared touch screen is equipped with a circuit board frame in front of the display. The circuit board arranges infrared emitting tubes and infrared receiving tubes on the four sides of the screen to form a horizontal and vertical infrared matrix. When the user touches the screen, the finger will block the horizontal and vertical infrared rays passing through the position, so the position of the touch point on the screen can be determined. Any touch object can change the infrared ray on the contact to realize the touch screen operation. The infrared touch screen is not subject to current, voltage and electrostatic interference, and is suitable for some harsh environmental conditions. Its main advantages are low price, easy installation, no need for card or any other controller, and it can be applied to computers of all levels.

The main part of the resistive touch screen is a resistive thin film screen that fits well with the display surface. Two layers of OTI transparent oxide metal conductive layers are coated on the reinforced glass surface. Pressure sensing is used for control. When a finger touches the screen. The two conductive layers contact at the touch point, and the resistance changes. Signals are generated in the X and Y directions and then transmitted to the touch screen controller. The controller detects this contact and calculates the position of (x, y) and then operates according to the way of simulating the mouse. The resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. However, because the outer layer of the composite film is made of plastic material, the explosion resistance is poor, and the service life is affected to a certain extent.

Surface acoustic wave is a kind of mechanical wave propagating along the surface of medium. An ultrasonic transducer is mounted on the corner of the touch screen. It can send a high-frequency sound wave across the screen surface. When the finger touches the screen, the sound wave on the contact is blocked, thereby determining the coordinate position. The surface acoustic wave touch screen is not affected by environmental factors such as temperature and humidity. It has high resolution, excellent scratch resistance, long service life, high light transmittance, and can maintain clear and bright image quality. It is most suitable for use in public places. However, dust, water and dirt will seriously affect its performance, which requires frequent maintenance to keep the screen clean.

This touch screen works by using the current induction of the human body. A layer of transparent special metal conductive material is pasted on the glass surface. When a conductive object touches it, the capacitance of the contact will be changed, so that the touched position can be detected. But there is no response when touched by a gloved hand or a hand-held non-conductive object because a more insulating medium is added. The capacitive touch screen can well sense light and fast touch, is scratch resistant, and is not afraid of dust, water and dirt. It is suitable for use in harsh environments. However, because the capacitance varies with temperature, humidity or environmental electric field, its stability is poor, its resolution is low, and it is easy to drift.

At present, the mainstream is multi touch, and Projected Capacitive multi touch, called PCAP for short. All jutouch touch panel mainly choose this PCAP technology. And the following touch performances are optional according to different final application:

As you see, a touch screen has been familiar to us today, as mobile devices such as smartphones achieved popularity. However, touch screens have been used in many occasions well before these mobile devices appeared.

Its intuitive operation is useful to users, and its high degree of freedom in design is advantageous for device makers. These factors back up the broad use of touch screens today. The technology advancement of touch screens has been

In tft-lcd, the TFT operates as a switch tube. The frequently made use of TFT is a three-terminal device. Make use of the voltage related to the gate to control the current between the resource and the leakage electrode. For screen screens, each pixel is structurally visible as a layer of liquid crystal sandwiched between the pixel electrode and also the usual electrode. A lot more notably, from an electrical viewpoint you can think about it as capacitance.

To bill the pixel P (I, j) in row j as well as column I, switch over T (I, j) on and also use the target voltage to the signal line D (I). When the pixel electrode is fully charged, the charge in the capacitor is maintained even if the switch is disconnected, and also the liquid crystal particles in between the electrodes remain to have an electrical area. The information (column) driver ACTS to apply the target voltage to the signal line, while eviction (row) chauffeur ACTS to activate and off. The trick to present the picture is additionally the molecular orientation of the liquid crystal under the action of an electric field. In general, the plan of LCD molecules can be warped by the alignment on the within the substratum to realize different display settings. Under the action of electric area, the positioning of liquid crystal particles modifications, and also the intensity of incident light adjustments after going through the liquid crystal layer via the coordination with the polarizer. To attain image display screen.

Tft-lcd colorization is usually attained by including a layer of color filter on the front panel of the display. It requires a black matrix of red, green, blue and shielding on each pixel.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.
