It should be noted that this design uses the COB method to integrate the POWERIC 21 on the FPC 2. At the same time, the BTOB connector can use the most commonly used BTOB connector in the consumer category. The connector can be bundled with the supplier to support it at the lowest price and make a popular product. Since many components are integrated on the FPC 2, as long as the FPC is made into a common shape, when this AMOLED module is shipped, the relevant important parts have been done well, and the customer only needs to add the corresponding connector to the main board, saving a lot of reconstruction of the peripheral circuit.

A BOOST module 215 and an Nchargepump module 216 are provided in the driver of the POWERIC21. At the same time, three LDO pins are also provided in the driver, and the BOOST module 215 is electrically connected to two of the LDO pins, while the Nchargepump module 216 is electrically connected to the other LDO pin. A VCC voltage pin 217, an ELVSS voltage pin 218, and an ELVCC voltage pin 219 are provided on the POWERIC21. The IOVCC pin 211 is electrically connected to the VCC voltage pin 217. The VCC voltage pin 217, the ELVSS voltage pin 218, and the ELVCC voltage pin 219 are respectively electrically connected to the three LDO pins in the driver of the POWERIC21. The BOOST module 215 is electrically connected to the Nchargepump module 216. It should be noted that this design can solve the influence of uncertain factors brought by wire routing and placement, so that in addition to providing voltages VCC, ELVDD, and ELVSS, the POWERIC21 can also obtain the IOVCC voltage through the method of VCC plus LDO, thereby achieving the purpose of simplifying the peripheral power supply circuit.

[0027] As Figure 1 shown in an embodiment, the FPC2 is electrically connected to the VIN pin and the EN pin in the display module respectively. It should be noted that this design can electrically connect the power supply pins on the periphery of the FPC2 AMOLED module.
