“…While there are a lot of difficulties, when realizing the narrow and symmetry border. Because of the LTPS technology, the left and right border can be very narrow, and the top frame can also be narrow due to fewer devices [3,4]. While the down border is usually wider than the other three sides due to the placement of the Demux TFT、 the fanout lines and the IC bump.…”

We have developed a panel design that integrated the demux TFT into the active area (MIA). By placing the demux TFT in the pixel area, we eliminate the impact of the TFT to realize the narrower border. We optimized the connection of demux devices and data lines to reduce the horizontal wire in layout. The influences of the special design were verified. By introducing the novel arrangement of the circuit, the 12.3 inch LCD panel with proposed circuit was fabricated with the narrow border , and the height of the down border was reduced by 200um.

“…In order to reduce the product border, the gate driver circuits integrated within the active area (GIA) technology has become one of the development directions. Some research is about gate fan-out [1,2]. The gate fan-out line is designed inside the AA, thereby reduce the wiring requirements of the border and realize the design of the narrow border.…”

In this article, we develop a new In‐cell touch TFT LCD display with gate driver circuits integrated within the active area and De‐mux driver. We designed a GOA driver circuit based on LTPS technology, which integrated GOA circuit into AA and realized In‐cell touch technology. Due to the LTPS technology, the GOA TFT device and wiring are integrated within pixels, and the loss of aperture rate is reduced. However, as the GOA circuit is integrated inside Pixel and simultaneously the panel uses De‐mux source driver and In‐cell touch driver, the display data is vulnerable to GOA signal interference. We solved the influence of GOA on display through the new pixel design and De‐mux driver. Finally, we made the 6.53″ De‐mux 1 to 3 In‐cell touch LCD display and got a good display effect.

“…In our study, we have tried to introduce new BPS material and novel structure design for uniformity PS height in active area (AA) and enhanced the process window [5]. In recent years, the narrow border or bezel less display technology become the mainstream market [6][7][8]. However, BPS technology only applies to the wide border display panel, typically larger than 6-7mm.…”
