In order to be the choice of hdtv, different kinds of displays develop much fast in the recent years. the dissertation introduces the development of all kinds of display, and gets the conclusion that, cpt still has the great advantage in the tv terminal field under the condition that the lcd is taking the place of cpt in the cdt field. the main research contents of cpt which includes high - luminance, high - contrast, high - definition, low - power, and complanation, have been investigated
本文系統地闡述了hdtv用的顯示器件的基本要求及其發展歷史和現狀，介紹了各類顯示器件欲成為hdtv終端顯示近年來所作的努力；總結出了雖然在彩色顯示器（ cdt ）領域，液晶顯示器（ lcd ）已經大有取而代之之勢，但是在電視終端領域，彩色顯像管（ cpt ）還是有其不可替代的巨大優勢；並分析了高亮度、高對比度、高解析度、低功耗、平面化等cpt製造的關鍵技術和研究動向。 -

In this thesis, the image enhancement was also studied, such as dlti 、 dcti ( digital luminance 、 color transient improvement ), peaking ( luminance peaking ), ble ( black - level enhancement ), brightness 、 hue 、 contrast and saturation adjustment, and then the hardware circuit was designed
研究了dlti （數字亮度瞬態增強） ， dcti （數字色度瞬態增強） ， peaking （亮度峰化） ， ble （黑電平延伸） ，亮度、色調、對比度和飽和度調整等圖像增強技術，並完成了圖像增強電路的設計。 -
According to the characteristic of ieee 1394 with wide bandwidth, common and real - time, the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite. before engineering realization, carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface. we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4. 5m to 100m ), compared with analog videos, have no geometric distortion, and have better luminance, contrast, definition
作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。 -
It is proved that the formula is exclusive in this test system by experiment. the standard tft - lcd module has been tested by this test software, including contrast ratio, color chromaticity, viewing angle, bad dot and luminance. these tested data are compared with those parameters of standard tft - lcd module, which proved that varying amplitudes are all in the required region of tft - lcd module testing
應用本測試軟體對經檢驗合格的標準tft - lcd模塊進行測試，測試內容主要為對比度、色度、視角范圍、壞點、亮度等，將測得的數據與標準tft - lcd模塊的參數進行比較，其數據變化幅度均在tft - lcd模塊測試所規定的范圍之內，符合tft - lcd模塊測試的要求。
