我和我的小伙伴都惊呆了，居然这么叠罗汉！

开始拆迁：

BOE的面板 HT150X02-100：

接近500V的背光电压，吓到我了：

一查，果然500V：

接上 A133 发现只能亮一下，自动黑屏，

经过半小时折腾，终于发现玄机，在 VGA 转接板上面有一个控制电压：

c41c0301-c193-446f-9cc4-fc94f81ecec1-0a5da296e8b81faf70b65f8cbb002ee.jpg

强制拉高即可：

一切 OK，终于点亮。

这个天马15寸屏，背光电压是12V，所以接电源非常方便。

今天再来整个活，闲鱼买个15寸屏试一试。

使用两个以上的屏幕
在 Android 9 及更低版本中，SurfaceFlinger 和 DisplayManagerService 假设最多存在两个物理屏幕，其硬编码 ID 分别为 0 和 1。

从 Android 10 开始，SurfaceFlinger 可以利用 Hardware Composer (HWC) API 生成稳定的屏幕 ID，使其能够管理任意数量的物理屏幕。如需了解详情，请参阅静态屏幕标识符。

在从 SurfaceControl#getPhysicalDisplayIds 或 DisplayEventReceiver 热插拔事件获取 64 位屏幕 ID 后，框架可以通过 SurfaceControl#getPhysicalDisplayToken 查找物理屏幕的 IBinder 令牌。

注意：不支持按屏幕进行 VSYNC。所有屏幕均由主内部屏幕的 VSYNC 信号驱动。
在 Android 10 及更低版本中，主内部屏幕为 TYPE_INTERNAL，所有辅助屏幕都将标记为 TYPE_EXTERNAL（无论连接类型如何）。因此，其他内部屏幕被视为外部屏幕。临时解决方法是，如果 HWC 已知且端口分配逻辑可预测，特定于设备的代码可以对 DisplayAddress.Physical#getPort 作出假设。
