Specification of 1.69-inch small lcd display
initial code for 1.69-inch small lcd display
Customize the length, width and thickness of FPC or cable, adjust the pin arrangement according to the interface type, and select the appropriate connector. Make your display or circuit board simple and safe with an excellent FPC solution.
A touch screen can be added according to your requirements, there are three options: resistive touch screen, capacitive touch screen, infrared touch screen. Or add protective glass as needed
Display screens with different optical parameters can be designed according to needs, such as brightness, color gamut, response time, gamma and other parameters, and anti-glare, anti-fingerprint coatings, etc. can also be added
The circuit board we designed can convert the interface of your display into an HDMI interface. If your product does not have any display control capabilities, you can use our serial display and only need to use simple commands to control the displayed content through RS232/458
1.69-inch tft Display drawings and interfaces
1.69-inch IPS mode lcd screen, full viewing Angle, resolution 240×280, drive IC ST7789, 4-line SPI interface, backlight with 3 LED lights in parallel, working voltage :3V, working current :60mA, module brightness: 350cd/㎡, the product meets Rohs standard. The FPC is connected to your motherboard by welding. You can replace other connection methods, such as ZIF or BTB, according to your needs.
The outline drawing is as follows:
Interfaces are defined as follows：
| Pin | Symbol | Detail |
| 1 | GND | |
| 2 | LEDK | backlight unit power supply |
| 3 | LEDA | SPI interface input/output pin. The data is latched on the rising edge of the SCL signal. |
| 4 | VDD | This is a voltage supply pin. It must be connected to external source |
| 5 | GND | GND |
| 6 | GND | GND |
| 7 | DC | Display data/command selection pin in 4-line serial interface. |
| 8 | CS | Chip selection pin; Low enable, high disable. |
| 9 | SCL | This pin is used to be serial interface clock |
| 10 | SDA | This pin is used to be serial interface clock |
| 11 | RES | This signal will reset the device and it must be applied to properly initialize the chip. Signal is active low. |
| 12 | GND |
1.69 -inch 240x280 tft display application cases
The slim ratio of 1.69-inch tft display is also suitable for the smart watch market, which can make your smart wear products more beautiful than the competitors’ products. At the same time, the production capacity, price and service life of LCD products are greatly improved compared with OLED.
The 1.69-inch tft display is also suitable for small instruments and other products that need to display more content. The nearly 1:1 display ratio makes the 1.69 display perfect for small devices, looking more coordinated and proportioned well.
