The VA type 5V liquid crystal screen in black with 4-digit 7-segment display and 37 pins is a common type of liquid crystal display device.
Display type: Utilizes VA (vertical orientation) liquid crystal technology. This technology's liquid crystal screen has high contrast, with a dark base like ink, and can present clear and prominent display effects. 4-bit 7-segment display means it can display 4-bit numbers or characters, each consisting of 7 fields, achieving 0-9 digit display and some simple symbol display by controlling the on/off state of different fields.
Working voltage: The working voltage is 5V, which is a common voltage specification, making it easy to connect with most microcontrollers and circuit systems, without the need for complex voltage conversion circuits.
Pin count: It has 37 pins. These pins are used to connect external circuits to drive and control the display, including power input, data transmission, control signal input, and other functions.
Operating temperature: It can generally operate normally within the temperature range of -20℃ to 70℃, meeting the usage requirements of most ordinary environments.
Application fields: Due to its clear display effect and simple control method, it is often used in automotive electronics, instrument and equipment, household appliances, smart watches, office equipment, and medical equipment. For example, digital displays on car dashboards and time displays on electronic clocks.
