顯示電源芯片
顯示電源芯片整合多項(xiàng)組件來滿足系統(tǒng)電源的需求，包括step-up or step-down pulse width modulation，PWM，DC-to-DC converters，low-dropout regulators，LDO regulators，voltage detectors，operational amplifiers， level shifters或其他零組件。 針對(duì)顯示屏應(yīng)用，顯示電源芯片提供適當(dāng)及穩(wěn)定的電壓予source drivers，gate drivers，timing controllers及panel cells; 此外，顯示電源芯片的內(nèi)置過度高溫及過載電流保護(hù)裝置能預(yù)防其他零組件于異常狀況受到破壞。 持續(xù)整合其他零組件于顯示電源芯片為目前主要趨勢(shì)，我們相信顯示電源芯片將持續(xù)為 TFT-LCD 及 OLED 顯示屏的主要零件。
