DESIGN PATTERNS JAVA COMPANION
Design patterns began to be recognized more formally in the early
1990s by Helm (1990) and Erich Gamma (1992), who described patterns
incorporated in the GUI application framework, ET++. The culmination of
these discussions and a number of technical meetings was the publication of
the parent book in this series, Design Patterns -- Elements of Reusable
Software, by Gamma, Helm, Johnson and Vlissides.(1995). This book,
commonly referred to as the Gang of Four or “GoF” book, has had a powerful
impact on those seeking to understand how to use design patterns and has
become an all-time best seller. We will refer to this groundbreaking book as
Design Patterns, throughout this book and The Design Patterns Smalltalk
Companion (Alpert, Brown and Woolf, 1998) as the Smalltalk Companion.
LCD Driver datasheet
The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of
supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source
driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of
SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power
consumption.
