Why TI is not making complete projector?

Other Parts Discussed in Thread: DLP4710

Hi,

My question is quite awkward, why Ti doesn't making own projector?

TI provides mostly all main parts.

TI company can provide optical module by giving job to designers. Why TI forwards customers to third party design company?

Why DLP EVM are so costly? Like DLP4710 EVM.

Is it really cost that much if I make projector with that DLP chip by myself? 

What do you think about %cost of main elements? Like I am thinking that DLP chip requires 60% of capital cost, processor will require 20% capital cost,, optical engine will require 5to7% capital cost, and remaining for other.

Last question,What is the brightness specification of DLP4710? Some datasheets tells 1500 lumens(according to pico chip) and some datasheets tells upto 4000 lumens(according to diagonal of dlp chip). 

Thanks

    Dear Dipak,
    Thank you for your interest in DLP Technology. The brightness of a projection system depends on illumination source and optical efficiency. TI manufactures DLP chipsets for a wide range of applications and brightness level from tens of lumens to ten thousands.

    TI does not specify brightness for a DMD chip because optical system design and thermal management limit maximum achievable brightness. The size (diagonal size of array) and package (thermal capability) will impact the brightness. Normally, bigger DMD array size will enable higher brightness level. System designers should ensure that DMD chip is operating within specification as per data sheet (thermal & electrical) for proper operation.

    Regards,
    Vivek
