3.5V VA LCD Display with Negative High Contrast and 12 O'clock Viewing Angle

3.5 Volt Custom LCD Display / VA Negative High Contrast LCD Transmissive Display Module

Product Details

3.5 Volt Custom LCD Display / VA Negative Contrast LCD Transmission Display Module, is a high-contrast LCD display device that adopts VA (vertical alignment) liquid crystal technology, with a working voltage of 3.5V, supporting customization and using negative display mode. Here is its detailed introduction and usage description:

Display Screen Core Introduction

Core Principle and Display Characteristics: The VA liquid crystal molecules in this module are in a vertical alignment state when not powered, and will tilt with the voltage change after being powered, thereby controlling the amount of light passing through to achieve imaging. The low working voltage of 3.5V meets the power supply requirements of most small electronic devices, and the energy consumption control is reasonable. In negative display mode, the screen background is dark when not powered, and the display content is light. Combined with the native high contrast (usually above 3000:1) of VA technology, the light display content will be clearer and more eye-catching on a dark background, and can be easily read even in strong light conditions. At the same time, the viewing angle of the VA panel is better than that of traditional TN screens, and when viewed from different angles (up, down, left, right), the color and brightness attenuation is small, and no obvious color bias will occur.

Customization and Structural Parameters: Customization is reflected in many aspects, such as being able to adjust the screen size and display area size according to requirements, to adapt to the installation space of different devices; the interface can be customized to common types such as I2C and SPI, facilitating connection with different motherboards; it can also be customized with silk-screen patterns and display segment layout, to meet the display requirements of specific scenarios. Its transmission display module usually includes liquid crystal panels, driving ICs (such as CN91C4S48 and other models), FPC flexible circuit boards, etc. Some are equipped with white LED backlighting, further enhancing the display effect in low-light environments, and the working temperature can often cover a wide range of -30℃ to 85℃, adapting to harsh environments.

Shortcomings: Due to the characteristics of VA liquid crystal technology, its response time is slower compared to TN and IPS panels. When displaying high-speed dynamic images, it may cause slight ghosting. Therefore, it is more suitable for static or low-speed changing information display rather than high-dynamic scenes.

Main applications

Automotive electronics field: Suitable for auxiliary control panels or instrument panels of motorcycles, electric vehicles and cars, which can display information such as speed, battery level, mileage, fault codes, etc. The high contrast of VA enables drivers to quickly read data while driving, and its wide temperature range feature can adapt to outdoor working environments of vehicles under high-temperature exposure or low-temperature cold conditions, such as the battery level display panels of some electric vehicles.

Industrial instruments and meters: Widely used in multimeters, thermometers, power detectors, charging stations and other devices. These devices usually require the display of stable numerical information. The high contrast of this module ensures clear and accurate measurement data, and the 3.5V low power consumption meets the battery power supply requirements of the instruments. Customized interfaces and display layouts can also match the functional requirements of different instruments, such as the charging amount and remaining time display on the charging station.

Smart home devices: Can be used in smart control panels, home appliance control modules, etc., such as central air conditioning zone controllers, status display panels of smart locks, etc. The negative display effect combined with high contrast makes it clear to see the operating mode, temperature, and lock status of the equipment, and the customized size can be embedded in the shells of different smart home devices. The 3.5V low voltage also meets the low power consumption design requirements of home devices.

Small consumer electronics: Applicable to portable blood glucose meters, electronic thermometers, small counters, etc. for small medical and civilian equipment. These devices have strict requirements for power consumption and size. The low voltage, small size customization advantages of this module are obvious. At the same time, the high contrast enables users to quickly obtain key health data or count results, improving usability.
