Distinguished Paper: A Third Generation Timing Controller And Column Driver Architecture Using Point-to-Point Differential Signaling
Building upon the strengths of National’s LVDS and RSDS technology solutions in digital video-data communications, we have created a completely new architecture that fully addresses the needs of TV while supporting existing platforms. The Point-to-Point Differential Signaling (PPDS™ ) architecture is more than a data link between the timing controller and the column driver. It is an architecture that supports very large displays with features like multiple windows each with its own gamma, various gamma optimizations, color balance at every gray level, minimal bezel size, a 30-bit and beyond color path to the display surface, four-color mosaics and numerous other benefits. |

A New Driving Method to Compensate for Row Line Signal Propagation Delays in an AMLCD
The distributed capacitive and resistive nature of both the row and column lines in an AMLCD introduces significant propagation delays to their respective addressing signals. The row signal delay is conventionally accommodated by shorteningthe row select time, which requires lower TFT on-resistance to provide adequate charging ratios of the pixels. We present a new approach to column driving which results in a much-improved pixel-charging ratio. The benefit is of particular interest to large-area, high-resolution, wide-aspect-ratio, LCD TVs. |

A New Intra-Panel Interface for Large Size/ High Resolution TFT-LCD Applications
In this paper, we describe a new intra-panel interface designed specifically to meet the needs of the LCD TV market and similar large size/ high resolution TFT-LCDs. We investigate the technical challenges and feature requirements of today's panels that prompted a new look at the panel interface. |

Image Processing Applied to Small Format Displays
The application of TFT displays for handset applications requires new display system architectures to have on-chip image processing in order to accommodate a direct camera connection. Other image processing techniques like stochastic dithering are required to reduce the size of the on-chip frame buffer thus reducing power and silicon real estate utilization, while preserving high image quality. The purpose of this paper is to explore the applicability of certain key image processing techniques, which add value to display column drivers with respect to their typical usage. The benefits and caveats of these image processing methods with respect to power and system bandwidth are articulated and their hardware requirements are discussed. |

Handset Architecture with Integrated Framestore/SourceDriver IC
The application of TFT displays for handset applications requires new display system architectures in order to achieve desired power targets and to enable handset features such as integrated cameras. There are significant benefits to embedding a framestore into the source driver chip of a handset display system. This paper explores these benefits with respect to typical handset usage models, power consumption, memory architecture, camera/video functions, and other advanced techniques for display power optimization. In particular, both the system power consumption and the source driver interface bandwidth requirement will be greatly reduced. These and other benefits are discussed, and the architecture of a TFT handset display system incorporating such and embedded framestore is described. |

A Liquid Crystal Display Response Time Compensation Feature Integrated into an LCD Panel Timing Controller
The electro-optic response times of the principal LCD modes are not fast enough for video applications. Applying a one-frame acceleration voltage, in lieu of the correct video command, can compensate the slow response time. This paper discusses the operation and design choices of a timing controller with an embedded LCD response time compensator (RTC). |

System Design Considerations for TFT-LCD Panels Using Sample and Hold Based Column Drivers
In this paper, we outline the unique system requirements of a flat panel display that uses sample and hold base column drivers. The basic operation and system consideration of the sample and hold architecture are compared to the traditional R-DAC architecture, specifically in terms of output performance and accuracy. |

SID'01 WhisperBus™ (pdf 106KB)
Increasing video data rates to liquid crystal displays brought about by increasing display format sizes and increased grayscale content are placing very high demands on digital data busses. These higher data rates coupled with constraints on EMI levels, size, power and component count are rendering CMOS data busses inadequate for the connection between the timing controller and the column drivers. The operation and performance of a comprehensive solution using a current signaling method (WhisperBus™) is presented. |

Integrated TFT- LCD Timing Controllers With RSDS Column Driver interface
A new generation of TFT LCD Timing controllers (TCON) are developed. This TCON offers higher levels of integration by integrating the industry de facto FPD Interface standard, LVDS receiver. In addition, This TCON provides support for multiple LCD Panel Design. This Timing Controller also features a new Column Driver interface, RSDS ?, Reduce Swing Differential Signaling. Through the implementation of this high speed interface, higher resolutions at reduced EMI can be achieved. This paper will review the technical features of this new TCON, FPD87310. |

LVDS goes the distance!
LVDS is the indisputable de-facto standard for notebook digital displays today. LDI (LVDS Display Interface) extends this technology to desktop applications, supporting high-resolution panels (QXGA), and enhances the cable drive capability to provide a robust, long, low cost interface. This paper discusses the performance of the new DS90C387/DS90CF388 LDI chipset. |
