Optical and Electrical Details for Display Evaluation
These specifications help engineers review display readability, backlight driving requirements, MCU interface compatibility, and LCD response time before prototype integration.
FSTN Positive Transflective Display
The FSTN positive transflective display mode allows the module to be reviewed for ambient-light readability and backlit operation. The white LED backlight is driven through pins A and K, with a typical backlight supply voltage of 3.5 V.
Top 30°, bottom 60°, left 45°, right 45°.
The optical characteristics table specifies a contrast ratio of 5.
The datasheet specifies Tr + Tf at 300 ms typ. and 400 ms max. at 25°C.
The datasheet lists backlight luminance without LCD as 496 cd/m² min. and 620 cd/m² typ. Final perceived display brightness should be reviewed through sample evaluation.
Connector and 16-Pin Parallel Interface Details
The module uses a 16-pin parallel interface with RS, R/W, E, DB0 to DB7, logic power, contrast adjustment, and backlight power pins. If the project requires assembled pins or a specific mating connector, confirm the physical connection option with DisplayModule before ordering.
MPU Signal Review
The ST7066U controller supports 4-bit or 8-bit MPU interface operation. The module pinout exposes DB0 to DB7, so the final bus mode should be selected in firmware and verified with the initialization sequence during sample testing.
Mechanical Integration Notes
The mechanical drawing is shown above for quick review. Use the official datasheet to confirm viewing area, active area, pin placement, mounting holes, PCB outline, and backlight structure before enclosure tooling or PCB release.
Window and Mounting Review
Check the LCD viewing window, mounting-hole positions, pin row location, and board clearance against the drawing before designing the front panel and PCB fixture.
Display Character Layout
The 16 x 2 character arrangement should be reviewed together with DDRAM addressing, font table, and product UI text length during firmware development.
Contrast Adjustment
Pin VO is used for LCD contrast adjustment. Confirm contrast circuit values and viewing direction during prototype evaluation.
Pin Row Review
Confirm the 16-pin row position, pin pitch, and assembly clearance against the datasheet before final PCB and enclosure release.
Reliability and Operating Conditions
These test conditions help customers review environmental tolerance before sample evaluation and product design. Final suitability should be validated in the target device, enclosure, power design, and operating environment.
Temperature Storage
High-temperature storage is listed at 80°C for 200 hours. Low-temperature storage is listed at -30°C for 200 hours.
Temperature Operation
High-temperature operation is listed at 70°C for 200 hours. Low-temperature operation is listed at -20°C for 200 hours.
Humidity Review
The datasheet lists high-temperature and humidity operation at 60°C and 90%RH for 96 hours under no-load conditions, excluding the polarizer.
Thermal Shock
The thermal shock test condition is listed as -20°C to 70°C for 10 cycles.
Vibration Test
The datasheet lists a vibration test at 10-55 Hz with 1.5mm total fixed amplitude, one 60-second cycle, in X, Y, and Z directions for 16 minutes each.
Static Electricity Test
The static electricity test is listed as VS=800 V, RS=1.5 kΩ, CS=100 pF, one application.
Engineering Notes Before Sample Evaluation
Review these items before sample testing and PCB release to reduce avoidable layout, firmware, and front-panel changes.
Power and Backlight
Check VDD logic supply, backlight voltage, and backlight current before setting the power path and current-limiting circuit.
Bus Mode
The ST7066U supports 4-bit and 8-bit MPU operation. Confirm which bus mode will be used before firmware initialization.
Font Mapping
Review the built-in font table before final UI text approval, especially when Japanese or European character requirements are part of the project.
Mechanical Fit
Confirm LCD window, mounting holes, pin direction, module thickness, and any pin-header requirement before placing a volume order.
FAQ for B2B Product Selection
These answers help purchasing and engineering teams review the module before sample testing, PCB layout, and volume ordering.
Does this module include a touch panel?
No touch controller IC or touch panel specification is provided for DM-LCD1602-429. If touch is required, confirm the exact touch configuration with DisplayModule before ordering.
What interface should be reviewed for PCB design?
The module uses a 6800 Series MPU Interface with RS, R/W, E, and DB0 to DB7 data lines. Review the pin description, timing characteristics, and selected bus mode before layout.
What optical values are available?
The datasheet provides viewing angles, response time, contrast ratio, and backlight luminance without LCD. Brightness at final assembly level should be reviewed through sample testing.
Can the character set be used for Japanese or European text?
The provided product information lists Japanese and European font support, and the ST7066U documentation describes 240-character CGROM options. Confirm the required character codes against the official font table before firmware release.
What should be confirmed before volume purchasing?
Confirm the datasheet revision, display appearance, pin-header or connector option, backlight driving method, font mapping, sample availability, MOQ, and factory lead time with DisplayModule.
