驱动ic是用固定针脚与pcb连接的，由于lcd通常需要许多驱动输入（即使使用了多路驱动技术），因此这些固定针脚的质量是决定液晶产品可靠性的关键因素。

For industrial, automotive, and portable equipment designers, Chip-on-Glass (COG) liquid crystal display (LCD) modules offer many advantages compared to traditional LCD modules with a packaged LCD driver.

The PCF8538 and PCA8538 are fully featured Chip-On-Glass (COG) Liquid Crystal Display (LCD) drivers, designed for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:9. They generate the drive signals for a static or multiplexed LCD containing up to 9 backplanes, 102 segments, and up to 918 elements. They feature an

2023年5月31日 · 显示驱动芯片 （DDIC）是显示面板制造中的一个关键部件。 通常，无晶圆厂IC设计公司（如 联咏科技 、 奇景光电 和 LX Semicon）设计DDIC，在半导体 晶圆代工厂 中采用不同的工艺节点（以微米 [µm]或纳米 [nm]为单位）制造IC芯片。 晶圆代工厂作为原始设备制造商（OEM）与IC公司合作，或为分包商制造关系。 之后， IC封装和测试公司 完成DDIC的后道工序。 然后，DDIC被交付给显示面板厂商，将IC粘合在面板上，实现显示信号驱动功能。 本文来 …

To address this issue, NXP has developed a Chip-on-Glass (COG) LCD driver approach whereby the integrated circuit mounts directly on the display glass, with the overall impact being a reduction in system cost. COG is a very reliable and well-established technology, which is often used in the automobile industry.

All EA DOG displays are manufactured using chip-on-glass technology. These display are very flat and can be combined with a wide variety of lighting (including RGB). Thanks to pins, our COG display are easy to assemble and versatile (also as a single piece).

NXP semiconductors describes the Chip-On-Glass technology (COG) in this white-paper, whereby the integrated circuit driving the display mounts directly on the display glass, thus reducing the system cost. COG is a very reliable and well established technology, and offers very thin profile LCD display modules at lower cost.

The Flash-based, power-managed, LCD PIC microcontroller family meets low power design requirements including driving the LCD display in Sleep mode while maintaining desired functional features. With the ability to select from an array of available LCD PIC microcontrollers, a designer can provide additional value by creating scalable designs

单芯片方案(One Chip Solution)将TCON、Source IC和Gate IC三个芯片均整合进一颗芯片内，由这颗单一芯片完成显示面板驱动的所有功能。 单芯片方案相对分离型方案，引入多种先进技术，大幅减少芯片使用量及外围电路，简化芯片供应链管理难度。

ST7 software LCD driver Introduction This note describes a technique for driving Liquid Crystal Displays (LCD) with any standard ST7 Microcontroller (MCU) i.e without any specific on-chip LCD driver hardware. This technique offers a solution for applications which require a display at low cost together with
