FPC custom service

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 display customization service

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

Optical Measuring Instruments

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

HDMI to MIPI,RGB,LVDS adapter board

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

2.9-inch two-color E-paper Display drawings and interfaces

Electronic paper on the display is a very special product, does not consume electricity does not refresh the picture, does not emit light itself, can only reflect the outside light. Suitable for use in bright environment with high battery life requirement. There are also differences between driving e-paper and LCD displays:
1, the screen write data 0x00 represents black, write data 0xFF represents white
2. Confirm the Busy level of the screen each time you update data. When it is low, you can update it.
3. Every time the screen is configured with a new display interface, it needs to reset its position.
4. During the refresh process, the electronic paper screen will blink and display normally after the refresh. It takes about three seconds to refresh a frame on black and white e-paper.

The outline drawing is as follows:

Interfaces are defined as follows:

2GDRN-Channel MOSFET Gate Drive Control 
3RESECurrent Sense Input for the Control Loop
5VSH2Positive Source driving voltage(Red) 
6TSCLI2C Interface to digital temperature sensor Clock pin 
7TSDAI2C Interface to digital temperature sensor Data pin
8BS1Bus Interface selection pin
9BUSYBusy state output pin
10RESEReset signal input. Active Low. 
11DCData /Command control pin 
12CSChip select input pin
13SCLSerial Clock pin (SPI)
14SDASerial Data pin (SPI)
15VDDIOPower Supply for interface logic pins It should be
connected with VCI 
16VCIPower Supply for the chip
18VDDCore logic power pin VDD can be regulated
internally from VCI. A capacitor should be
connected between VDD and VSS
19VPPTest pin
20VSH1Positive Source driving voltage 
21VGHPower Supply pin for Positive Gate driving voltage and VSH1
22VSL Negative Source driving voltage
23VGLPower Supply pin for Negative Gate driving voltage
24VCOMVCOM driving voltage 

2.9 -inch 128x296 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.
