What is an LCD driver
LCD driver is an IC used to store display data transmitted from microcontrollers and drive LCD panels.
The Epson LCD driver has built-in RAM, which enables ultra-low power LCD display.
Overview of Epson LCD Controller
Characteristics of Epson controller
Epson LCDC reduces the load on the host CPU through its unique image processing unit, achieving low-power
and high-speed image rendering. Epson LCDC produces various types of display controllers, such as memory displays,
STNs, and TFTs, which are widely used.
The main applications of Epson LCDC
Epson”s LCDC covers the main resolutions of TFT LCD modules, especially in industrial applications. Adding Epson”s
LCDC as a plugin to the CPU can efficiently achieve color display in a short period of time.
Convert monochrome TFT display to color
There are several factors to consider when converting a monochrome TFT display to color. Firstly, it requires an increase
in the amount of data required for display, as well as higher storage capacity and processing hardware performance. For example,
for a monochrome QVGA (320×240 pixels, 16 grayscale levels) panel, the data capacity of a single image is calculated as
follows: 320x240x4 bits=76800×4 bytes=38400 bytes. In contrast, a full-color QVGA panel (16 million colors, 8 bits per RGB
channel) requires 320x240x24 bits=76800×24 bits=230400 bytes,
which is six times more than monochrome. There are significant differences in the processing and memory requirements
for handling and transmitting image data between monochrome displays and color displays.
If the CPU lacks the necessary specifications, it may be necessary to replace the entire CPU, resulting in significant workload
and cost. However, introducing an Epson LCD controller can achieve colorization without the need to replace the CPU, effectively utilizing existing hardware.
