TIANMA NL8060BC21-11KG Industrial LCD

Working temperature (rear shielding surface) TopR -30+80 ℃

Relative humidity (≤ 40 ℃) RH-95% without condensation

Absolute humidity (80 ℃) AH-70 g/m ³ is equivalent to 24% RH

Engineering Tip: If the working environment exceeds the above limits, irreversible damage may occur even in a short period of time. Especially the combination of humidity and temperature - high temperature and humidity can accelerate the aging of polarizing film and the oxidation of touch screen.

Connection: FPC (40 pin+60 pin), compatible with socket FH28-40S-0.5SH/FH28-60S-0.5SH

Attention: Touch performance may be affected by the usage environment (screen moisture, glove thickness), and parameters need to be adjusted through the controller board.

Interface definition and signal mapping

4.1 LCD signal board connector CN1

Using JAE FI-SE20P-HFE socket (20 pin), paired with FI-S20S plug. The pin definitions are as follows (only key pins are listed):

Pin symbol function notes

1,2 D3 ± pixel data (MAP A/B) 8-bit or 6-bit

3 DPS scanning direction H: reverse; L/Open: Forward

4 FRC color selection H: 16.7M; L/Open: 262k

5 GND Ground

6,7 CLK ± pixel clock

9,10 D2 ± pixel data/DE

12,13 D1 ± pixel data

15,16 D0 ± pixel data

18 MSL LVDS mapping selection L/Open: MAP A; H: MAP B

19,20 VCC 3.3V power supply must be fully connected

Important note: LVDS differential pairs must use twisted pair cables with a characteristic impedance of 100 Ω and be matched with the transmitter.

4.2 LVDS Data Mapping

NL8060BC21-11KG supports three input combinations (see Data Manual Table 4.7.1):

Combination input data bit FRC MSL display color

① 8-bit MAP A high/low/on 16.7M

② 8-bit MAP B height 16.7m

③ 6 bits low/on low/on 262k

The difference between MAP A and MAP B lies in the allocation of RGB bits and DE (data enable). When actually replacing, it is necessary to confirm the output mapping of the original system LVDS transmitter and select the matching mode through the MSL pin, otherwise color distortion or image shift may occur.

4.3 Backlight connector CN2

Use JST SM08B-SRSS-TB (8 pins), corresponding to socket SHR-08V-S. Pin definition:

1: A1 (anode 1)

2: K1 (cathode 1)

3: A2

4: K2

5: A3

6: K3

7: A4

8: K4

Wiring reminder: The 4-channel LED is independent, and the anode or cathode cannot be connected in parallel at will, otherwise it will cause uneven current. It is recommended to use 4 independent constant current sources or a driver board with current equalization design.

4.4 Touch screen connection CN3/CN4

CN3 (40 pin FPC) and CN4 (60 pin FPC) are respectively connected to the touch screen controller.

The manufacturer recommends using the recommended controller board, otherwise drivers need to be developed and parameters adjusted independently.

Power supply timing and power on requirements

5.1 LCD Signal Board Timing

Before VCC rises to 3.0 V, all display signals (D0 ±~D3 ±, CLK ±) and function signals (DPS, FRC, MSL) must remain in a low or high impedance state.

Only when VCC is stable and effective, can LVDS signals be inputted.

If the display signal is cut off during the working process, even if it is input again, the module may not be able to recover normally. At this time, VCC must be turned off and powered back on at the same time.

Strongly recommend: first connect VCC, then send LVDS signal; Stop the LVDS signal before cutting off VCC during power outage.

5.2 Backlight timing sequence

The backlight should be turned on after the display signal is valid (VALID period) to avoid unstable display images when powered on. Before turning off the backlight, the LVDS signal should be stopped first.

5.3 Fuse Description

The VCC power supply circuit is equipped with FCC1620AB fuse (KAMAYA, rated 2.0 A, melting current 4.0 A). The rated current of the system power supply must be greater than 4.0 A, otherwise when the module is short circuited internally, the fuse may not be able to quickly melt, resulting in smoke or odor.
