The data sheet indicates that for a resistor of 91 kΩ at V CC =5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 μs and 28.6 μs instead of 37 μs. If a display with the recommended 91 kΩ resistor is powered from 3.3 volts the oscillator will run much slower.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
The display driver model from Windows 8.1 and Windows Phone have converged into a unified model for Windows 10. [43] A new memory model is implemented that gives each GPU a per-process virtual address space. Direct addressing of video memory is still supported by WDDMv2 for graphics hardware that requires it, but that is considered a legacy case.
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...

Most of the ASCII characters (the double quote is missing) on a 14-segment display. Multiple-segment display devices use fewer elements than a full dot-matrix display, and may produce a better character appearance where the segments are shaped appropriately. This can reduce power consumption and the number of driver components.
Motorola 6845 CRT controller. The Motorola 6845, or MC6845, is a display controller that was widely used in 8-bit computers during the 1980s. [1] [2] Originally intended for designs based on the Motorola 6800 CPU and given a related part number, it was more widely used alongside various other processors, and was most commonly found in machines based on the Zilog Z80 and MOS 6502.
[18] [16] A single byte can encode the full state of a seven-segment display, including the decimal point. The most popular bit encodings are gfedcba and abcdefg. In the gfedcba representation, a byte value of 0x06 would turn on segments "c" and "b", which would display a "1". 16×8 grid showing the 128 states of a seven-segment display [19]
