18-Bit RGB: Used to describe a clocked parallel TFT connection that uses 18 data lines (6 for Red, 6 for Green, 6 for Blue) as well as Hsync, Vsync, data enable, and pixel clock to transfer data to the TFT. Theoretical color depth is 218 or 262,144 colors.
24-Bit RGB: Used to describe a clocked parallel TFT connection that uses 24 data lines (8 for Red, 8 for Green, 8 for Blue) as well as Hsync, Vsync data enable, and pixel clock to transfer data to the TFT. Theoretical color depth is 224 or 16,777,216 colors.
6800 is a parallel interface that uses Read/Write signal and an Enable signal to control the data bus. Communications with a display are only enabled when the enable signal is pulled high. The level of the Read/Write signal then determines whether data will be read from the display or written to the display. If the … Read more 6800
8080 is a parallel interface that uses separate Read and Write lines to control the data bus. Difference Between 8080 and 6800 The other common parallel interface is 6800 which uses a single Read/Write signal in combination with an Enable signal to control the data bus. Questions? If you have any questions, please contact our knowledgeable … Read more 8080
AMOLED is Active Matrix OLED. An Active Matrix OLED uses a TFT (Thin Film Transistor) transistor-per-pixel architecture. Using a transistor-per-pixel allows higher resolution displays to be made and avoids the problems associated with high duty cycle passive displays. Detailed Definition In an AMOLED, once a pixel is turned on, it can stay on for the … Read more AMOLED
ATX stands for Advanced Technology eXtended and refers to a specification for motherboard and power supply configuration introduced in 1995. ATX remains the most common motherboard configuration, though different form factors have since been introduced. When “ATX” is used at Crystalfontz, it indicates that the module is configured to control the ATX power supply of … Read more ATX
A backlight is used behind the LCD glass to allow the LCM to be read in dark conditions. The vast majority of backlights are now LED. Historically there were also EL (electroluminescent) and CCFL (Cold Cathode Fluorescent Light) backlights, but as LED efficiency has increased and cost has decreased, EL and CCFL backlights have all … Read more Backlight
BGA stands for Ball Grid Array. A type of high-density electronic component package for integrated circuits. The BGA has solder balls on its backside, which line up with corresponding contacts on the front side of the PCB. The part and PCB are heated until the solder balls melt. The surface tension of the molten solder … Read more BGA
CABC stands for Content Adaptive Backlight Control. Normally an LCD’s backlight is set to the brightness that will make a white pixel fully illuminated. CABC automatically dims the backlight to the lowest level required for the brightest pixel on the display. Simultaneously, the controller lightens the image by the same amount. Overall, there is no … Read more CABC
CGRAM stands for Character Generator RAM. Character LCDs include a fixed CGROM to define the bulk of the characters they display. However, since the CGROM cannot be changed the designers also included the CGRAM — a small number of characters (typically 8) that can be redefined at run-time. These eight characters are usually mapped to … Read more CGRAM
