擁有恒定電流，16通道的驅(qū)動(dòng)器結(jié)合完整的網(wǎng)點(diǎn)修正提供動(dòng)態(tài)的LED亮度控制 達(dá)拉斯（2007年11月7日）消息，德州儀器有限公司（簡(jiǎn)寫為TI）（NYSE: TXN）推出兩個(gè)16通道、恒流槽、發(fā)光二極管驅(qū)動(dòng)器結(jié)，合網(wǎng)點(diǎn)修正和灰度處理，用于集成電路上提高視頻質(zhì)量。驅(qū)動(dòng)器為設(shè)計(jì)者提高了系統(tǒng)可靠性和動(dòng)態(tài)亮度控制，以加強(qiáng)大面板上單一、多種或全色LED顯示器解決方案，以及LED信號(hào)板和逆光顯示。見(jiàn)：www.ti.com/tlc5942-pr 新TLC5942和TLC5945是TI流行的TLC5940家族延伸產(chǎn)品，此新產(chǎn)品可提供高性能容量，如模擬數(shù)字模塊，用于大型LED顯示器上集成的IC。TLC5942提供128步幅網(wǎng)點(diǎn)修正用于補(bǔ)償LED發(fā)光錯(cuò)配，并允許灰度控制和網(wǎng)點(diǎn)修正通過(guò)分離的，集中的串行接口。所有16通道的最大電流值可由單一外部電阻器來(lái)設(shè)置。高電流可由平行通道提供。TLC5945是專門優(yōu)化有于視頻顯示，實(shí)現(xiàn)快速視頻行為，如大型露天活動(dòng)，不用繼電器就可提供快速的刷新速率（30-MHz數(shù)據(jù)傳輸率）。 [FONT=times] original text [/FONT] [font=times][Color=#708090]Constant-Current, 16-Channel Drivers with Integrated Dot Correction Provide Dynamic LED Brightness Control DALLAS （Nov. 7, 2007） - Texas Instruments Incorporated （TI） （NYSE: TXN） introduced today two 16-channel, constant-current sink, light-emitting diode （LED） drivers with dot correction and grayscale on one integrated circuit （IC） for high-quality video. The drivers give designers increased system reliability and dynamic brightness control to enhance the resolution for large-panel mono-, multi- or full-color LED displays, LED signboards and display backlighting. See: www.ti.com/tlc5942-pr. An extension of TI‘s popular TLC5940 family, the new TLC5942 and TLC5945 provide high-performance capabilities, such as analog and digital dimming, in an integrated IC for large LED displays. The TLC5942 provides 128 step dot correction to compensate for LED luminous mismatch, and allows for both grayscale control and dot correction to be accessible via separate, dedicated serial interface ports. The maximum current value of all 16 channels can be set by a single external resistor. Higher currents can be provided by paralleling channels. The TLC5945 is optimized for video displays with fast video action, such as stadium sporting events, as it provides a very fast refresh rate capability - 30-MHz data transfer rate - with no delay.
