UC8176 的数据手册中不包含 LUT 相关指令的说明，但是 UC8151 的手册里有，且格式是一样的，故把 UC8151 的手册也放了上来。
OTP 目录为从屏幕中读取出的 OTP 数据:
- `bw.txt`: 黑白屏
- `3c.txt`: 黑白红三色屏
可从 OTP 数据中提取屏幕内置的 LUT 波形作为参考，以方便自定义 LUT 波形。
以下是从 OTP 中提取出的 LUT 波形例子（均已测试和本项目支持的 2 个屏幕不加载外部 LUT 时在 20 度左右室温下显示效果一致）：
**黑白屏：**

使用以下 LUT 且把驱动设置为 BW 模式可把三色屏当作黑白屏使用，刷新时间能从 15s 降到 2-3s 左右：
> - 有待继续优化，显示效果比默认三色的 LUT 淡一些
> - 刷新时间应该还有优化的空间，理论上来说应该还可以做一个支持局刷的 LUT
