This application report presents part 2 of the flat panel display design guidelines. - Inductive Based Switch Reg Circuits Provide High Efficiency White LED Drives (Rev. B)PDF, 135 Kb, Revision: B, File published: May 6, 2013
White LEDs are quickly becoming the light of choice for backlighting of small color displays because of their falling costs, longer life, and smaller size. The problem this presents is that the white LED has a high voltage drop (3.1 V to 4.0 V depending on manufacturer) as compared to the monochrome displays' green LED with a voltage drop of 1.8 V to 2.7 V. Whereas the green LED can be powered dir - Working With Boost ConvertersPDF, 159 Kb, File published: Jun 15, 2015
This brief note highlights some of the more common pitfalls when using boost regulators. These includemaximum achievable output current and voltage, short circuit behavior and basic layout issues. It isassumed that the reader is familiar with the basic operation of a boost regulator. - AN-1234 RSDSв„ў Flat Panel Display Design Guidelines Part 1 (Rev. A)PDF, 245 Kb, Revision: A, File published: May 6, 2013
This application report outlines the total system solution that Texas Instruments provides for flat panel displays (FPDs). The described design uses an reduced swing differential signaling (RSDS) interface technology for reduced power, reduced board size, reduced component count, and reduced EMI. This document is currently applicable to XGA and SXGA notebook and monitor applications. - Integration Simplifies TFT Power DesignsPDF, 144 Kb, File published: Mar 6, 2003
