Kunlun Tongtai touch screen touch calibration

The most far-reaching technological change in touchscreen performance is the shift from resistive to capacitive touchscreen technology. According to iSuppli, a market research agency, nearly 25% of touchscreen mobile phones will be transferred from resistive to capacitive touchscreens by 2011. Capacitive touch screen technology brings ...

After receiving the touch signal, the capacitive touch screen converts the touch data into electrical pulses and transmits it to the touch screen control IC for processing. The signal is amplified by a low-noise amplifier (LNA), then converted and demodulated by analog-to-digital ratio, and finally sent to a DSP for data processing. Electricity...

Kunlun touch screen is a positioning device, the user can directly enter coordinate information by pointing to the computer, just like a mouse and keyboard, it is also an input device. Kunlun touch screen has many advantages such as durability, fast response, space saving, and convenient communication. With this technique, ...

What is the reason why the variable cannot be deleted? Use the Usage Count Check command to check variable usage, and then you can delete variables that aren't being used. If a variable cannot be deleted, it means that the variable is in use and cannot be deleted. Is it possible to view the device while it is running?

How to choose the touch screen model in the Kunlun Tongtai software, this is selected according to the model of the touch screen. Before you can choose a model, you need to determine what type of touchscreen you use on your device. Different models of touch screens, some with high configuration, some with low configuration, but the configuration is ...

1. Touch screen (touchscreen), also known as "touch screen" and "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts.

1. The meaning is different Resistive Screen: A resistive touch screen is a touch screen product controlled by pressure sensing. Capacitive screen: Capacitive screen, also known as capacitive touch screen, is a four-layer composite glass screen that uses capacitive touch technology to work. 2. The working principle is different Electricity...

1. Surface acoustic wave screen The three corners of the acoustic screen are pasted with transducers that transmit and receive sound waves in the X and Y directions respectively (transducers: made of special ceramic materials, divided into transmitting transducers and receiving transducers. It is to convert the electrical signal sent by the controller through the touch screen cable into sound.

Mitsubishi PLC: Programming port parameter setting ...

1. The film surface of the touch screen is the touch surface, that is, the front of the product; The glass side is non-touch, i.e. the back of the product 2. The touch screen part is a glass product, the corners of the glass are sharp, please wear gloves/finger sleeves when assembling 3. The touch screen part is a fragile glass product, and it should not be touched during assembly.

1. Connect the touch screen with the PLC We know the communication between two pieces of hardware, whether wireless or wired. The first step is to establish a connection. The most common connection between PLC and touch screen is serial data cable connection. The data cable can be used in a treasure ...

70. Omron PLC: Parent device parameter settings (1) The communication parameter setting of the parent device of the universal serial port should correspond to the communication parameter setting of the PLC serial port, and the default standard parameters of the PLC are set to: 9600, 7, 2, E (even check); (2) Users can set it according to their needs, and it is recommended to ...

Classification of capacitive touch screens Capacitive touch screens are divided into two categories, one is surface capacitive touch screen, and the other is projected capacitive touch screen, and projected capacitive can also be subdivided into self-capacitive and mutual capacitive. Among them, the surface capacitive and projected self-capacitive touch screen can only achieve ...

Analysis and treatment method of touch all-in-one screen fault Fault 1: Touch deviation phenomenon: The position touched by the finger does not coincide with the mouse arrow. Analysis: After installing the driver, there was no vertical touch to the bullseye center position when correcting the position. Place...

1. Do not hit with metal objects. Usually the HMI will be covered with a layer of glass to protect the screen and make it easy to touch. However, the glass is fragile, do not hit the screen with metal objects during use, it is easy to cause the glass to be scratched or broken. 2. Avoid squeezing the screen with heavy objects. Around HMI ...
