42.2: LCD‐TV System with 2.8Gbps/Lane Intra‐Panel Interface for 3D TV Applications

Abstract

This paper presents LCD-TV system with newly proposed 2.8Gbps/lane intra-panel interface for 3D TV applications. The proposed intra-panel interface transfers data in a point-to-point manner with embedded clock. Scrambling scheme was applied to stabilize loop bandwidth of bang-bang CDR, and to minimize EMI radiation. Timing controller (TCON) and source driver (SD) are implemented using 65nm/1.2V and 0.18um/1.8V CMOS processes, respectively. 2.8Gbps operation was verified by increasing horizontal blanking period while driving a 55-inch Full-HD LCD panel with 8-bit RGB and 120Hz frame rate. The proposed interface demonstrates the possibility of implementing an intrapanel system of 240Hz FHD LCD-TV for 3D displays with just one pair of differential data lines per SD.

47‐1: Invited Paper: A 6Gbps Intra‐Panel Interface with Video Image Compression for Next Generation Displays

“…The proposed VIC supports a 1/2 compression ratio to double the data bandwidth. Compared with the conventional system employing 9b/10b coding [4], the proposed receiver can improve the effective bandwidth by a factor of 2.18 with the proposed combined ACC and VIC structure, as shown in Figure 1. Although channel loss is reduced significantly by halving the required data rate, it still reaches to 22-dB.…”

A 13‐bit universal column driver for various displays of OLED and LCD

“…Therefore, the column driver for OLED needs to realize separated DACs to support separate gamma corrections. Moreover, the data protocol between timing controller(TCON) and column drivers is various according to applications . Because of this difference, column drivers have been developed for each application.…”

“…Unfortunately, the increased data rate coupled with long transmission channel (i.e., composed of PCB, FPC, and glass panel) length has made the intra-panel interface the main source of EMI in display systems [1]. To resolve the EMI radiation issue, previous works have adopted a conventional method of scrambling the high-speed display data to eliminate any periodicity that can induce energy spikes at harmonic frequencies of repetition [1][2]. The scrambling function, however, can increase the dynamic current of the interface system because data randomization can simultaneously increase the data toggle ratio.…”
