1.7 Inch 128 * 64 LCD Display FFSTN Negative 1.8V 21 PIN LCD Display Parallel

FFSTN (Film-Film Super Twisted Nematic):

• FFSTN is an advanced form of STN (Super Twisted Nematic) LCD technology, where two layers of film (instead of one) are used in the liquid crystal structure. This design enhances contrast, viewing angles, and image clarity compared to standard STN.

• FFSTN displays typically offer:

  • Better Contrast: Higher contrast ratios, make the display easier to read in various lighting conditions.

  • Improved Viewing Angles: FFSTN displays allow you to view the screen from more angles with less distortion compared to standard STN displays.

  • Color Options: The display itself is typically monochrome (black on a light background or vice versa), but the backlighting can be different colors (e.g., white, blue, or green), enhancing visibility in low-light conditions.

Detailed Parameters:

1.7-inch 128×64 dot matrix liquid crystal display is a common type of liquid crystal display module. The LCD technology it adopts is FFSTN (Film Compensated Super Twisted Nematic). Its working voltage is -1.8V, and the 21-pin parallel interface is used for connection with external circuits. The following is a detailed introduction of it:

Product Introduction

Basic parameters: The panel size of this monitor is 1.7 inches, with a resolution of 128×64 pixels. This means it can display 128 columns and 64 rows of pixel points, capable of clearly presenting text, numbers, and simple graphics.
Display technology: It adopts FFSTN technology, which is based on STN liquid crystal technology and adds compensation film to eliminate chromatic dispersion, achieving black-on-white display effect with high contrast and wide viewing angle. Negative FFSTN usually displays black background with white text, providing a clear and eye-catching visual effect.
Interface type: 21-pin parallel interface. This interface has a fast data transmission speed and can achieve high-speed data exchange with external devices such as microcontrollers. Common parallel interface signals include data bus (such as D0-D7), register selection signal (RS), read/write signal (R/W), enable signal (E), etc.
Working voltage: The working voltage is -1.8V. The low-voltage working characteristic makes its power consumption lower, suitable for devices powered by batteries.
Driver chip: Different manufacturers' this model of monitor may use different driver chips, such as ST7565R. The driver chip is responsible for controlling the display operation of the liquid crystal display, such as the on/off of pixel points and the setting of display modes.

Product application

Instrumentation: It can display various measurement data, such as voltage, current, temperature, humidity, etc., and is commonly found in multimeters, thermometers, hygrometers, etc.
Embedded systems: In embedded devices such as smart home control panels and industrial controllers, it is used to display the working status, operation menus, parameter settings, etc. of the equipment.
Medical equipment: Such as blood glucose meters, blood pressure monitors, etc., can clearly display measurement results and related prompt information, making it convenient for medical staff and patients to view.
Automotive electronics: It can be used in vehicle instrument panels to display vehicle status information such as speed, engine speed, fuel level, water temperature, etc., and can also be used for simple information display in in-vehicle navigation systems.
Portable electronic devices: Such as handheld game consoles, electronic dictionaries, portable data collectors, etc., can provide a clear display interface to meet users' information display needs.
