  2. Hitachi HD44780 LCD controller - Wikipedia

    en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller

    The 7-bit ASCII subset for the Japanese version is non-standard: it supplies a Yen symbol where the backslash character is normally found, and left and right arrow symbols in place of tilde and the rubout character. A limited number of custom characters can be programmed into the device in the form of a bitmap using special commands.

  3. Liquid-crystal display - Wikipedia

    en.wikipedia.org/wiki/Liquid-crystal_display

    A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information.

  4. List of file signatures - Wikipedia

    en.wikipedia.org/wiki/List_of_file_signatures

    In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.

  5. FPD-Link - Wikipedia

    en.wikipedia.org/wiki/FPD-Link

    The I2C master can read and write to all the slaves on the other side of the FPD-Link III chipset, which is effectively transparent to the I2C master and slaves communications. For example, this enables infotainment head units to control and configure displays, and image processing units to control and configure cameras using the same twisted ...

    Bit 7 = 1: Digital input. If set, the following bit definitions apply: Bits 6–4: Bit depth: 000 = undefined 001 = 6 010 = 8 011 = 10 100 = 12 101 = 14 110 = 16 bits per color 111 = reserved Bits 3–0: Video interface: 0000 = undefined 0001 = DVI 0010 = HDMIa 0011 = HDMIb 0100 = MDDI 0101 = DisplayPort Bit 7 = 0: Analog input. If clear, the ...

  7. Cholesteric liquid crystal - Wikipedia

    en.wikipedia.org/wiki/Cholesteric_liquid_crystal

    The image shows a rotation of the director about 180° in a cholesteric phase. The corresponding distance is the half-pitch, p/2. A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral.

  8. Liquid crystal on silicon - Wikipedia

    en.wikipedia.org/wiki/Liquid_crystal_on_silicon

    For example, a chip with XGA resolution has an array of 1024×768 pixels, each with an independently addressable transistor. [5] In the LCoS device, a complementary metal–oxide–semiconductor (CMOS) chip controls the voltage on square reflective aluminium electrodes buried just below the chip surface, each controlling one pixel.

  9. Display Data Channel - Wikipedia

    en.wikipedia.org/wiki/Display_Data_Channel

    Extended display identification data (EDID) is a companion standard; it defines a compact binary file format describing the monitor's capabilities and supported graphics modes, stored in a read-only memory chip programmed by the manufacturer of the monitor. The format uses a description block containing 128 bytes of data, with optional ...
