有大佬看看怎么让lcd屏幕不闪烁吗？
switch(key_temp)
case '1': //界面切换按键
ADC_Data.LCD_Page++;
if(ADC_Data.LCD_Page>1)
ADC_Data.LCD_Page=0;
switch(ADC_Data.LCD_Page)

{
case 0:
LCD_Clear(White);

LCD_DisplayStringLine(Line2," main ");
ADC_Flag = 0;
adc_temp = Read_ADC();
sprintf(string,"%s%.2f%s","volt:",adc_temp,"V");
LCD_DisplayStringLine(Line4,string);

LCD_ADC_Status();

break;
case 1:
LCD_Clear(White);

LCD_DisplayStringLine(Line2," Setting ");

sprintf(string,"%s%.2f%s","MaxVolt:",up,"V");
LCD_DisplayStringLine(Line4,string);
sprintf(string,"%s%.2f%s","MinVolt:",down,"V");
LCD_DisplayStringLine(Line5,string);

LCD_DisplayStringLine(Line6,"Upper: ");
LCD_DisplayStringLine(Line7,"Lower: ");
break;
