星火一号开发板 LCD不显示

工程在RT-Thread Studio上基于星火一号开发板创建的模板工程，后在ENV里面打开LCD驱动，和SRAM，在更新软件包和生成MDK工程后下载到开发板上，发现LCD屏不亮，反而19颗全彩LED灯亮了，恳请大佬们看看什么原因

```c
#include <rtthread.h>
#include <rtdevice.h>
#include <board.h>

#include <drv_lcd.h>
//#include <rttlogo.h>

#define DBG_TAG "main"
#define DBG_LVL         DBG_LOG
#include <rtdbg.h>

/* 配置 LED 灯引脚 */
//#define PIN_LED_B              GET_PIN(F, 11)      // PF11 :  LED_B        --> LED
//#define PIN_LED_R              GET_PIN(F, 12)      // PF12 :  LED_R        --> LED

int main(void)
{
	 lcd_clear(WHITE);

/* show RT-Thread logo */
    //lcd_show_image(0, 0, 240, 69, image_rttlogo);

/* set the background color and foreground color */       //设置背景色和前景色
    lcd_set_color(WHITE, BLACK);

/* show some string on lcd */    //在液晶显示器上显示一些字符串
    lcd_show_string(10, 69, 16, "Hello, RT-Thread!");
    lcd_show_string(10, 69 + 16, 24, "RT-Thread");
    lcd_show_string(10, 69 + 16 + 24, 32, "RT-Thread");

/* draw a line on lcd */     //在液晶显示器上画一条线
    lcd_draw_line(0, 69 + 16 + 24 + 32, 240, 69 + 16 + 24 + 32);

/* draw a concentric circles */  //画一个同心圆
    lcd_draw_point(120, 194);
    for (int i = 0; i < 46; i += 4)
    {
        lcd_draw_circle(120, 194, i);
    }

return 0;

}
