降低显示屏的刷新频率
目前希望降低8寸群创屏幕的刷新频率,请问应该如何修改内核文件? 怎么做 static struct da8xx_panel known_lcd_panels[] ={= {
.name = "NHD-8.0-ATXI#-T-1",
.width = 800,
.height = 600,
.hfp = 112,
.hbp = 88,
.hsw = 48,
.vfp = 21,
.vbp = 39,
.vsw = 3,
.pxl_clk = 40000000,
.invert_pxl_clk = 0,
},
= {
/* 800 x 600 @ 60 HzReduced blanking VESA CVT 0.79M3-R */
.name = "nxp-800x600@60",
.width = 800,
.height = 600,
.hfp = 42, //39 //45
.hbp = 144, //151 //170
.hsw = 58, //63
.vfp = 1, // 1
.vbp = 25, //23
.vsw = 3, // 3
.pxl_clk = 41000000, //43000000
.invert_pxl_clk = 0,
},//wince
听说是修改这个结构就可以降低频率,
1. 我用的是群创的800*600的8寸屏幕,请问我到底是改对应的5还是9结构体。
2. 请问目前的设置是每秒 60HZ吗? 怎样调整到30Hz,如果是修改.pxl_clk ,怎样调整?
