+#### 1. 简介
+
+用于 GD32F470 立创开发板配套 RGB LCD 屏幕的驱动，支持触摸。
+
+> **原作者：LCKFB**  
+> 本驱动最初由 LCKFB 开发，由 godmial 移植到本BSP。
+
+#### 2. 在 ENV 中的开启  
+ps：建议全部开启  
+```
+Hardware Drivers Config  --->
+      Board extended module Drivers --->
+                            Enable LCD --->
+                                - [*]Enable TLI
+                                - [*]Enable SDRAM
+                                - [*]Enable TOUCH
+                                - [*]Enable GPU
+                                - [*]Enable DRAW PANEL EXAMPLE
+```
+
+#### 3. 注意事项
+
+1. 如果屏幕出现刷新抖动，触摸屏出现连点的情况，可以尝试在 `libraries\GD32F4xx_Firmware_Library\CMSIS\GD\GD32F4xx\Source\system_gd32f4xx.c` 将时钟值修改为  
+   `#define __SYSTEM_CLOCK_240M_PLL_25M_HXTAL       (uint32_t)(240000000)`  
+   然后重新编译即可
+
+2. 由于代码格式审查原因，本驱动未包含中文显示函数。但可直接移植官方源码中的中文显示函数进行使用。
+
+3. 为避免 `scons` 命令编译不通过，代码使用了如下代码段以适配不同编译器：
+   ```
+   #if defined(__CC_ARM) || defined(__ARMCC_VERSION)
+   // Keil MDK
+   uint16_t ltdc_lcd_framebuf0[800][480] __attribute__((at(LCD_FRAME_BUF_ADDR)));
+   #elif defined(__GNUC__)
+   // GCC (RT-Thread)
+   uint16_t ltdc_lcd_framebuf0[10][10]; // 此行为避免 scons 编译错误而添加
+   #endif
+
+
