屏幕

這個(gè)功能之所以單獨(dú)列出來(lái)，是由于其可有可無(wú)。如果一個(gè)嵌入式系統(tǒng)只是作為一個(gè)連接器連接外圍設(shè)備模塊，通過(guò)相關(guān)接口連接到電腦主機(jī)或者直接掛在網(wǎng)絡(luò)上，那么屏幕就不需要了。但是如果做出來(lái)的是一個(gè)消費(fèi)類產(chǎn)品，與用戶交互頻繁，這就不得不嘮叨幾句。

電容屏幕是嵌入式屏幕的首選，在電路設(shè)計(jì)中需要注意觸屏連接線和顯示屏連接線的布局。在走線的過(guò)程中盡量短的靠近主控cpu，同時(shí)注意配對(duì)信號(hào)走差分線，RGB控制信號(hào)走等長(zhǎng)。各種信號(hào)走線間距遵循3W規(guī)則，避免相互干擾。在屏幕的設(shè)計(jì)中，一定要確保功率和防止干擾，以防屏幕閃屏和花屏現(xiàn)象的出現(xiàn)。
