After being buffered , read by blocks and plus - width - modulating ( also called pwm ) , the digital video signal will be converted into scanning signal for color moving picture and then be outputted to the display board 系統(tǒng)將多媒體視頻卡輸出的數(shù)字視頻信號(hào)進(jìn)行數(shù)據(jù)緩存、分塊讀取和脈寬調(diào)制等處理,形成符合顯示板結(jié)構(gòu)的彩色運(yùn)動(dòng)圖像掃描信號(hào),輸出到顯示板。
The pixel circuit can make oled emit light . continuously , while the peripheral driving circuit is designed to provide correct input signals for amoled , for instance , provide the line - by - line scanning signals for row electrode of oled matrix and the data 文中還將dvi ( digitalvisualinterface )接口引入和應(yīng)用于外圍驅(qū)動(dòng)系統(tǒng)當(dāng)中,使視頻顯示電路同有源oled外圍驅(qū)動(dòng)電路相接合,為amoled顯示屏提供了一個(gè)簡(jiǎn)單實(shí)用的測(cè)試驅(qū)動(dòng)平臺(tái)。
The run stm program includes the control of scanning signal , supervise and control the running state , set the scan range , set parameters , set and acquire the clock , collect and save the image signal , etc . image manipulation functions includes : on the space of the wipe of speckle , smooth image , blur , step sharp image , laplace sharp , and automatically adjust contrast , etc Stm運(yùn)行程序包括掃描信號(hào)控制、運(yùn)行狀態(tài)監(jiān)控、設(shè)置運(yùn)行參數(shù),設(shè)置并獲得時(shí)基、圖像信號(hào)采集存取等等。圖像處理功能包括在空間域上的去斑、圖像平滑、模糊、圖像的梯度銳化、拉譜拉斯銳化,對(duì)比度自動(dòng)調(diào)整等等功能,在頻域空間上完成數(shù)字圖像的傅立葉變換,并討論了理想高低通濾波。
Current tv system has two types : one is the 60hz based system , the other is the 50hz . the phenomenon of large area flicker is not obvious in the 60hz based system , so the scanning converter uses the way of converting the 60hz and 50hz based interlaced scanning signal to 60hz based progressive scanning signal . employing this way the converter can not only reduce the large area flicker and interline twitter , but erase the raster and display finer and smoother pictures 現(xiàn)行的電視制式有60hz和50hz系統(tǒng)兩種,在60hz系統(tǒng)里,大面積閃爍不是很明顯,因而本掃描轉(zhuǎn)換器采用將60hz和50hz的隔行掃描信號(hào)統(tǒng)一處理成60hz的逐行掃描信號(hào)的方法,這樣可一方面使大面積閃爍和行間閃爍都比較輕,又可消除行結(jié)構(gòu),重現(xiàn)細(xì)膩圖像。
