【摘要】：AMOLED顯示屏由于具有輕薄、對比度高、可以實現(xiàn)柔性顯示等優(yōu)勢,被廣泛認(rèn)可為繼CRT和TFT-LCD之后的第三代顯示器。玻璃基板的AMOLED顯示屏經(jīng)過十余年的發(fā)展,技術(shù)已趨成熟。而柔性基板的AMOLED顯示屏技術(shù)處于起步階段,現(xiàn)各面板廠商正積極進(jìn)行柔性可彎曲、可折疊顯示技術(shù)的開發(fā)。柔性可折疊AMOLED技術(shù)有兩個研究方向,本文選取了其中一個技術(shù)方向,針對其驅(qū)動系統(tǒng)進(jìn)行了研究。本文的研究內(nèi)容主要包括:第一,如何解決兩顆COF驅(qū)動芯片的同步控制問題?本文研究的技術(shù)方向采用兩顆驅(qū)動芯片,而顯示屏的畫面顯示內(nèi)容需要統(tǒng)一和同步,業(yè)界目前無商業(yè)化的時序控制器驅(qū)動方案,開發(fā)專用的時序控制器成本又太高,所以開發(fā)一種低成本的解決方案至關(guān)重要。第二,完成RGB TTL信號轉(zhuǎn)MIPI信號電路的研究及開發(fā);小尺寸AMOLED顯示屏的COF驅(qū)動芯片采用的是高速的MIPI信號,自開發(fā)的時序控制器采用的是TTL信號,開發(fā)一種驅(qū)動電路及其控制系統(tǒng),實現(xiàn)MIPI信號與TTL信號的轉(zhuǎn)換,是開發(fā)時序控制器必然會面臨的課題。第三,柵極電路控制信號模塊的開發(fā);柵極電路屬于AMOLED顯示屏的核心技術(shù),不同的電路需要配合不同的控制信號,各個面板廠商都期望開發(fā)出一種易于修改的柵極電路控制信號模塊。
[Abstract]:The AMOLED display screen is widely recognized as the third generation display after CRT and TFT-LCD because of its lightweight, high contrast, flexible display and other advantages. The AMOLED display screen of glass substrate has matured after more than ten years of development. The AMOLED display technology of flexible substrates is in its infancy. Now the panel manufacturers are actively developing flexible flexible and foldable display technology. There are two research directions in flexible foldable AMOLED technology, one of which is selected in this paper, and the driving system is studied. The main contents of this paper are as follows: first, how to solve the synchronization control problem of two COF driver chips? In this paper, two driving chips are used in the technical direction of the research, and the screen display content of the display screen needs to be unified and synchronized. There is no commercialized timing controller driving scheme in the industry, and the cost of developing a special timing controller is too high. So developing a low-cost solution is crucial. Secondly, the research and development of RGB TTL signal to MIPI signal circuit is completed. The small size AMOLED display COF driver chip uses high speed MIPI signal, and the self-developed timing controller uses TTL signal. Developing a driving circuit and its control system to realize the conversion between MIPI signal and TTL signal is an inevitable problem in the development of timing controller. Third, the development of the control signal module of the gate circuit, which belongs to the core technology of the AMOLED display screen, and different circuits need to cooperate with different control signals. Each panel manufacturer expects to develop an easy-to-modify gate circuit control signal module.
