Natural Science Forum / Physics / Optics / May 2005Where can I buy greyscale LCD panel?
I want to built an LCD projector by myself. Does anybody know where can i buy the LCD panel which is used to mudulate the light beam with images? Thank you! >I want to built an LCD projector by myself. > Does anybody know where can i buy the LCD panel which is used to > mudulate the light beam with images? > Thank you! sony LCX017DLT and associated chips: CXA2112R, CXA3106AQ, CXD3500R you can find datasheet from Sony or major distributor, Luigi thank you Luigi very much! it seems that LCX017DLT is exact the type i need. However it requires lots of circuit design. Is there any similar product which can be directly connected to a computer or a video card? > thank you Luigi very much! > it seems that LCX017DLT is exact the type i need.

Not sure if this is responsive to your request, but I seem to remember hobbyists some time back talking about cutting apart miniature B&W TV sets bought at Radio Shack as a way of getting a cheapo LCD panel and associated electronics . . . ??? I tried an LCD TV and an LCD projector. In both machine the LCD is sealed inside a metal box and I can not take the LCD out :( And I find many LCD module products which are usually used in cell phone etc. It is a pity that one side of the LCD is fixed to the PCB board also. Do you have more suggestion? Thank you so much! > thank you Luigi very much! > it seems that LCX017DLT is exact the type i need. However it requires > lots of circuit design.

I suggested the Sony because I used for modulating laser light to make videohologram. I understand that you want to make a projection system ,well I suggest you to use DLP technology, like this: http://www.tyrexsales.com/dlp/, it's better. otherwise go to this place: http://www.holoeye.com/lc_r_3000.html. but maybe the easyest thing is to buy an old used LCD projector, take the LCD panel together with dichroic prism and make some experiments. What exactly do you want to do? Luigi Actually what i need is quite simple: I have an optical system and want to modulate the intensity profile of my light beam with certain partterns. The spatial light modulator will be placed in the focal plane of a lens, and transmission mode is better, so I prefer LCD to MMD. I don't need very high resolution like 10 microns. Even 100 micron pixel size is acceptable to me. The best specifications I hope is: 2-4 inches in size, and the pixel number is larger than 640*480. No optical filter is inside so that all the visible light can pass through except some loss. Thanks. Buy and old LCD projector and take it apart and keep the electronics and drivers complete and just use the optics that you want with the LCD panels. You can then put the patterns you want on the LCD by making the patterns you want in Photoshop and then hooking your computer up to the projector connector and putting the digital image onto the LCD panel as you want. You might have to play around with the various images in Photoshop to beat the scaler chip artifacts. This approach is a poor mans developers kit for an LCD panel. Of course you could always purchase a developers kit for about US$10 to 15K or more, of course you will get drawings, documentation and support also. Michael www.oscintl.com I just tried an LCD projector. its lcd module is fixed in a metal box and i found no way to open the box. There are 3 LCDs inside the box, relative to RGB filters, respectively. But I need just one without the filter. Do you mean that for some projector models it is possible to open the LCD box? If so I would be very pleased to buy such one :) The metal box is probably a plastic housing. Each of the 3 LCD panels are aligned to the X-Cube and typically expoxied into place once aligned. If you are careful you can usually just cut or peel back these epoxy tabs on the corners of the LCD frame. This will enable you to have one of the LCD panels. Dont forget in your custom illumination system you will need to provide the panel with polarized light, so you may want to pull out the PCS (polarization conversion system) and the fly's eye array lenses and probably the color filters that go with each panel. For you all for your valuable suggestions! I decided to buy a SLM from holoeye finally. Its quality is not bad, and the price is acceptable. |
