A jungle chip, or jungle IC, is an integrated circuit (IC or "chip") found in most analog televisions of the 1990s. It takes a composite video signal from the radio frequency receiver electronics and turns it into separate RGB outputs that can be sent to the cathode ray tube to produce a display. This task had previously required separate ...
On-screen displays are also used in camcorders, and can display various information both on the viewfinder and on the TV set the camcorder is connected to. The complexity of graphics offered by such displays has greatly increased over the years, from simple monochrome images to intricate graphical user interfaces .
The CDP1861 was manufactured in a low-power CMOS technology, came in a 24-pin DIP (Dual in-line package), and required a minimum of external components to work.In 1802-based microcomputers, the CDP1861 (for the NTSC video format, CDP1864 variant for PAL), used the 1802's built-in DMA controller to display black and white (monochrome) bitmapped graphics on standard TV screens.
Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market ...
The display driver may itself be an application-specific microcontroller and may incorporate RAM, Flash memory, EEPROM and/or ROM. Fixed ROM may contain firmware and display fonts. A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)
Block diagram of a NEC μPD7220 graphics display controller. A video display controller (VDC), also called a display engine or display interface, is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system.
While horizontal scrolling is expected to present the illusion of a view port moving left and right across a wide panoramic scene made of screen memory, ANTIC's automatic memory scan increment conflicts with this idea that the rows of screen data is wider than the display. Presenting screen memory as long horizontal lines requires an LMS ...
MOS Technology VIC (PAL version 6561–101) Pinout diagram of the 6560 version of the MOS VIC chip. This circuit was packaged in a standard 40-pin DIP casing.. The VIC (Video Interface Chip), specifically known as the MOS Technology 6560 (NTSC version) / 6561 (PAL version), is the integrated circuit chip responsible for generating video graphics and sound in the VIC-20 home computer from ...
