FLEXIBLE PRINTED CIRCUIT BOARD AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17921887 titled 'FLEXIBLE PRINTED CIRCUIT BOARD AND DISPLAY DEVICE
Simplified Explanation
The patent application describes a flexible printed circuit board (PCB) and a display device that includes this PCB. The flexible PCB consists of a main PCB and a connection PCB with different outlines. Both PCBs can be single-layer or double-layer boards.
- The main PCB has a bonding region, a device mounting region, a first connection region, and signal lines.
- The signal lines include a first signal line positioned between the device mounting region and the first connection region, and a second signal line positioned between the device mounting region and the bonding region.
- The connection PCB has a second connection region, a third connection region, and a third signal line positioned between the second connection region and the third connection region.
- The two PCBs are connected using the first connection region and the second connection region.
- The third signal line on the connection PCB overlaps with the second signal line on the main PCB in an overlapping region.
- An electromagnetic shielding structure is provided on at least one side of either the main PCB or the connection PCB in the overlapping region.
Potential applications of this technology:
- Display devices such as smartphones, tablets, and televisions.
- Flexible electronic devices such as wearable devices, flexible sensors, and flexible displays.
Problems solved by this technology:
- Minimizing electromagnetic interference between signal lines on different PCBs.
- Ensuring reliable signal transmission between the main PCB and the connection PCB.
Benefits of this technology:
- Improved signal integrity and reduced signal loss.
- Enhanced reliability and performance of the display device.
- Flexibility in design and manufacturing of electronic devices.
Original Abstract Submitted
Provided are a flexible printed circuit board and a display device. The flexible printed circuit board comprises a main flexible printed circuit board and a connection flexible printed circuit board having different outlines. Both printed circuit boards are single-layer boards or double-layer boards. The main flexible printed circuit board comprises a bonding region, a device mounting region, a first connection region and signal lines. The signal lines include a first signal line positioned between the device mounting region and the first connection region, and a second signal line positioned between the device mounting region and the bonding region. The connection flexible printed circuit board comprises a second connection region, a third connection region and a third signal line positioned between the second connection region and the third connection region. The two flexible printed circuit boards are connected by means of the first connection region and the second connection region. An orthographic projection of the third signal line on the main flexible printed circuit board overlaps with the second signal line. In an overlapping region, an electromagnetic shielding structure is at least provided at one side of the main flexible printed circuit board facing the connection flexible printed circuit board or at one side of the connection flexible printed circuit board facing the main flexible printed circuit board.
