Specification of 2.13-inch e-paper display
Circuit diagram for 2.13-inch e-paper 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.
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 two-color E-paper Display drawings and interfaces
This is a 2.13-inch color electronic ink display with a resolution of 250×122 and an SPI interface that can display black and white images. Your images will be retained indefinitely in the event of a power loss – place the image, then turn off the power. Once these e-paper modules are updated, they don’t require any power and can actually be completely disconnected, with the content remaining on the display indefinitely, making them ideal for low-power devices powered by solar or batteries. It should be noted that every time the screen configures a new display interface, its position needs to be reset. The e-paper screen will flicker during the refreshing process, and it will display normally after refreshing.
The outline drawing is as follows:
Interfaces are defined as follows：
|N-Channel MOSFET Gate Drive Control
|Current Sense Input for the Control Loop
|Positive Source driving voltage(Red)
|I2C Interface to digital temperature sensor Clock pin
|I2C Interface to digital temperature sensor Data pin
|Bus Interface selection pin
|Busy state output pin
|Reset signal input. Active Low.
|Data /Command control pin
|Chip select input pin
|Serial Clock pin (SPI)
|Serial Data pin (SPI)
|Power Supply for interface logic pins It should be
connected with VCI
|Power Supply for the chip
|Core logic power pin VDD can be regulated
internally from VCI. A capacitor should be
connected between VDD and VSS
|Positive Source driving voltage
|Power Supply pin for Positive Gate driving voltage and VSH1
|Negative Source driving voltage
|Power Supply pin for Negative Gate driving voltage
VCOM and VSL
|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.
