Touch screen dimming fault analysis and treatment method - Hitec

As an input device, the touch screen has the advantages of easy to use, ruggedness, fast response time, and space saving, and the user can use it directly through the contact screen to complete the operation, without the need for a keyboard or mouse, and is very practical and widely used. ...

1. If it is the first time for the user to use the capacitive contact screen, it is recommended to first follow the detailed device driver in the manual, and then calibrate the screen according to the on-screen prompts. 2. In addition to ensuring the correct device of the system software, remember not to install two or more connections on a host.

The interior of the touch screen can be roughly divided into: communication interface unit, driver unit, memory variable unit, and display unit. In addition to the display unit, the other 3 units are invisible to us inside the touch screen. 1. Communication interface ...

1. Projective capacitive contacts Although the basic structure and working principle of the projected capacitive contact screen is the same as that of the four-wire impedance film, the projected capacitive impedance film does not pass through the contact field, but captures the change of capacitance between the electrodes. Generally speaking, when using the form of capacitive sensor, it can almost ...

Many people have encountered industrial contact screen contact no response, no matter how we point to the industrial contact screen is not responding, at this time many people don't know what to do, today let's take a look at what to do when encountering industrial contact screen contact no response. ...

Industrial-grade displays are displays that are used in industrial control links or equipment. The key difference between it and civilian or commercial displays is that the chassis planning is generally made of all-steel planning concepts, and the panel is divided into different materials such as iron plates, stainless iron, stainless steel, and aluminum panels. Industrial-grade display ...

HITECH is a *** in Taiwan, known as Hitech in Chinese mainland. It is the *** of Taiwan Quanyi Electronics Co., Ltd., which was established in 1981 and initially produced electronic watches for pens. In order to transform Quanyi into a technology-oriented company, in 1984 began to develop ...

1. First of all, we work on the SoftPanel program (this program generally does not create shortcuts on the desktop, users can click the [Start Menu] in the lower right corner of the desktop to find the SoftPanel in the list of applications called out). ...

1. Whether to select the correct communication protocol (Modbus, PROFIBUS, CANopen, EtherCAT) 2. Whether the communication cable is OK (RS232 RXD TXD GND RS485 A+ B- CANopen CAN_L CAN_H CAN_GND EtherCAT cable) 3. Is the communication parameter correct ...

Correct equipment, operation and maintenance of reducer is an important part of ensuring the normal operation of mechanical equipment. Therefore, in your device, first check whether the wiring interface is loose, and then check whether the serial port and interrupt number are conflicting, if there is resistance, you should adjust the resources to avoid resistance. Look again ...

Imprecise screen orientation: can be positioned from scratch by the driver software. Contact orientation and screen cursor inversion: When the device touches the screen, the orientation of the screen is inverted, please adjust the contact screen orientation according to the guidelines of the right-hand orientation. ...

Tablet PC, also known as industrial contact tablet, is an inductive LCD display device that can transmit keying signals such as auxiliary contacts, when touching the graphic buttons on the display screen, the haptic feedback system on the display screen can drive various connected devices according to the pre-programmed program, which can ...

The touch screen interface is the same as the general interface, in addition to the touch screen interface, other user interfaces include web interface, software interface, game interface and mobile phone interface. Touchscreen interfaces have many similarities with them: Fundamentally, they are all interactive systems, and they are all ...

Capacitive touch screen skills use human current to detect jobs. The capacitive touch screen is a 4-layer composite glass screen. The inner and outer surface of the glass screen and the interlayer are coated with a layer of ITO, and the outermost layer is a thin protective layer of silica glass. Sandwich ITO coating for the working surface, 4 edges guiding 4 electrodes, internal ITO for ...

1. Resistive contact screen Analog resistive screen The analog resistive contact screen is what we generally call the "resistive screen", which is a kind of contact screen that uses pressure sensing to operate. It uses two layers of ITO (indium tin oxide) plastic film coated with conductive function, two pieces of IT...

(1) Fault 1: Contact deviation Phenomenon 1: The direction of the finger does not coincide with the mouse arrow. Reason 1: After installing the driver, there is no vertical contact with the bullseye when calibrating the alignment. ...

Embedded device contact screens can be divided into five categories according to their technical principles: vector pressure sensing, resistive, capacitive, infrared, and surface acoustic waves. Among them, resistive contact screens are used more in embedded systems, and resistive contact screens can be divided into four wires, five wires, seven wires and so on. So so...

The full bonding process of capacitive touch screen - TP and LCM direct bonding parts include the VA area (i.e., the view area) and the part outside the VA area. What are the advantages of the optical lamination process selected for capacitive touch screens: 1. Capacitive touch screen ...

The communication method is selected to control the inverter to complete the system control function, and the user can control the operation of the system through the touch screen. Through the pressure transmitter installed on the outlet pipe network, the outlet pressure signal is turned into a 4-20mA or 0-10V standard signal and sent to the built-in PID adjustment of the PLC.

Resistance contact is divided into four-wire resistance and five-wire resistance contact, the simple difference is four wires and five wires in the functional area. A constant voltage of 5V is added to each layer of the two-layer transparent metal layer with four-wire resistance analogue technology: ...
