FPC/cable/interface customization
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.
Touch screen or cover glass added
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
Customized Display Optical Parameters
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
Customized HDMI to MIPI, RGB, LVDS boards
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
2.13-inch three-color E-paper Display drawings and interfaces
Electronic paper is a very special product in the display, does not consume electricity without refreshing the picture, does not emit light itself, can only reflect the outside light. It is suitable for the service environment with high requirements on battery life and bright environment. There are also differences in driving electronic paper and LCD display:
1, the screen write data 0x00 represents black, write data 0xFF represents white (note: black, white and red electronic paper 0xff represents red).
2. The Busy level of the screen should be confirmed every time the data is updated. When it is low, it can be updated.
3. Each time the screen is configured with a new display interface, it needs to reset its position.
4. The electronic paper screen will flicker in the process of refreshing, and will display normally after refreshing. It takes about 18s to refresh a frame on black, white and red electronic paper.
The outline drawing is as follows:
Interfaces are defined as follows：
| Pin | Symbol | Detail |
| 1 | NC | |
| 2 | GDR | N-Channel MOSFET Gate Drive Control |
| 3 | RESE | Current Sense Input for the Control Loop |
| 4 | NC | |
| 5 | VSH2 | Positive Source driving voltage(Red) |
| 6 | TSCL | I2C Interface to digital temperature sensor Clock pin |
| 7 | TSDA | I2C Interface to digital temperature sensor Data pin |
| 8 | BS1 | Bus Interface selection pin |
| 9 | BUSY | Busy state output pin |
| 10 | RESE | Reset signal input. Active Low. |
| 11 | DC | Data /Command control pin |
| 12 | CS | Chip select input pin |
| 13 | SCL | Serial Clock pin (SPI) |
| 14 | SDA | Serial Data pin (SPI) |
| 15 | VDDIO | Power Supply for interface logic pins It should be connected with VCI |
| 16 | VCI | Power Supply for the chip |
| 17 | VSS | GND |
| 18 | VDD | Core logic power pin VDD can be regulated internally from VCI. A capacitor should be connected between VDD and VSS |
| 19 | VPP | Test pin |
| 20 | VSH1 | Positive Source driving voltage |
| 21 | VGH | Power Supply pin for Positive Gate driving voltage and VSH1 |
| 22 | VSL | Negative Source driving voltage |
| 23 | VGL | Power Supply pin for Negative Gate driving voltage VCOM and VSL |
| 24 | VCOM | VCOM driving voltage |
2.13 -inch 122x250 e-paper application cases
Electronic price tags are the biggest market for e-paper. Electronic paper does not consume electricity without refreshing the picture, and can see a lot, so both black and white two-color electronic paper or red and white three-color electronic paper, can shine in the electronic price tag market. The mainstream sizes are 2.13 “and 2.99”, and electronic price tags can replace manual labor and improve efficiency without errors.
Electronic conference board is also a major application direction of electronic paper, no longer for frequent name change and worry, but also can display meeting content, booking information, can realize paperless office, intelligent office.
