Thinkpad w700 8BIT RGB Backlight [ HP DC( Dream color) 1]

leokim · 发表于 2012-3-22 23:16:03

It's been a while.  Recently , I have installed a " HP 8bit RGB backlight Dream color LCD" on Thinkpad w700 . It is a little bit complicated..

W700 Normal LCD : LTN170CT08 ( CCFL Backlight ) , 6BIT TN, 262,000 colors

Modified W700 LCD: HP DC1 ( Dream color)  , 8BIT TN, 16.7M colors, RGB LED Backlight

For FX3700 MXM Video card, EDID of Dream color lcd, Video bios of FX3700m should be modified  to solve LCD timing problems.

If you wanna install 10bit IPS DC2( Dream color) on thinkpad w700 , you should sacrifice display port. morever, you need a HP color mapping board, LCD cable etc.

I have compared w700 normal 6bit ccfl backlight lcd with a 8bit RGB led backlight lcd.

很明显的差别

leokim · 发表于 2012-3-23 00:07:54

For only 10bit IPS DC2, HP color mapping board ( STDP8028AB, LS-495BP) is required. For 8bit modification, there is no need a color mapping board.

这新换的屏，跟W701的RGB LED比起来如何？

degoxin · 发表于 2012-3-23 00:12:47

我的经验：
在W700换成W701的第一刻，就发现屏幕的亮度、色彩真的是有巨大的进步。

不知W701的屏，是否跟这块HP的8Bit DC差不多。

leokim · 发表于 2012-3-23 00:28:32

For w701, The lcd of w701 / w701ds is a 8bit RGB backlight LED ( Samsung LTN170CT08-L01 ) . Viewing angle of HP DC1 is a little bit wider than that of W701.

Arabesque · 发表于 2012-3-23 00:29:55

记得好像 Quadro显卡的话无需mapping board 原生支持10bit
A卡需要那玩意儿

leokim · 发表于 2012-3-23 00:35:56

If you see a pinout of mxm module, you know the more lvds signals are required for 10bit ips lcd application. The mxm module of w700 , w701 support 8bit lcd. For 10bit ips lcd,
Display port to LVDS conversion module ( Color mapping board) is required.

Thanks for sharing valuable information.

LZ看得懂中文吗？DC2屏幕在哪里可以买到呢？

degoxin · 发表于 2012-3-23 00:46:22

He should be able to read Chinese.
There are a couple of mistakes in his replies in English. So he might not be natively English-speaking.

leokim · 发表于 2012-3-23 00:57:35

As you comment, I can only read chinese by Google Translator.

My mother tongue is a korean.

leokim, My W701 has a screen issue, shown in the video. Would you please take a look and let me know what the potential issue could be? Thanks a million!

是个解码板
8bit显卡可以解码，然后输出到显示屏就行了
10bit有一部分显卡无法解码，HP用的是解码板解决这个问题，Dell这一代的工作站M4600和M6600才开始启用10bit的IPS，通过调用Quadro显卡解决这个问题
