“…Vertical Gate line In Pixel array (VGIP) is one effective method to achieve narrow border LCD, which is being studied a lot in consumer products [2,[4][5][6] before the mass production of a-Si integrated gate driver. Compared to a-Si TFT integrated gate driver, there is no important circuit around the panel edge, which eliminates the concerns of electrostatic damage or corrosion of the TFT circuits.…”

et al. 2018

Vertical gate line in pixel array is one effective method to achieve narrow border LCD. However, this design forms V-shape mura which matches the crossed point positions of the vertical gate line and horizontal gate line , if the pixel array design is not optimized. Through electronic simulation, this paper find out the root cause of the mura is the parasitic capacitance of gate line and data line. The optimum pixel array design is proposed to achieve better image quality of narrow border freeform LCDs for automotive application.

“…As shown in Figure 1, those voltage converters are used to convert the system input voltage level, VCI, to a higher voltage level (doubler) or a negative voltage (inverter) for the use of some function blocks in the TFT-LCD driver such as the gate drivers, the source drivers, and the VCOM drivers. Furthermore, the flicker issue in the TFT-LCD driver should be effectively solved by inversion-based techniques such as frame inversion, line inversion or dot inversion are commonly used to solve [1]- [3]. Basically, control methods used for LC polarity reversion function can be divided into two parts, which are the AC VCOM driving control and the DC VCOM driving control.…”

P‐55: A LCD Supplied by High Integrated Dual‐Side Dual‐Output Switched‐Capacitor Regulator with Only Two Flying Capacitors

This paper presents a high integrated dual-side dual-output (DSDO) switched-capacitor (SC) regulator with only two flying capacitors. Generally, a dual-phase voltage doubler and an inverter are used to supply positive and negative voltage for TFT-LCD gate drivers, respectively. Four flying capacitors, eight pinouts, and sixteen power switches are necessary for their operations in the driver integrated chip (IC). The proposed DSDO SC regulator combines both dual-phase voltage doubler and inverter converter into one channel through the use of time multiplexing technique at the cost of little performance degradation. As a result, it not only diminishes the number of flying capacitor from four to two but also removes four IC pinouts for low cost and compact size. Beside, sixteen necessary power switches are reduced to twelve for decreasing about 27% silicon area.
