Title: Method for a phone with content projector

Description:
BACKGROUND 
     Prior Art 
     This method for a phone with content projector relates to light transmitted from an illuminating system modulated by liquid crystal or the like information (image signals), and the modulated light is projected onto a screen, thereby achieving image display. 
     Incidentally, when light emitted from the illuminating system is applied to the liquid crystal light valves, the polarizers of the liquid produces heat. In this case the temperature of the polarizers is sometimes increased to a high temperature of about 80 C. This is because the light that is not transmitted by the polarizers is absorbed by the polarizers. 
     Several inventions were made to solve the problem on how to project an image onto a screen, the idea of a LCD projector exists since 1968, when Gene Dolgoff first thought about the idea of having an LCD projector, it took him several years to get the first prototype to work and he finally filed the U.S. Pat. No. 5,012,274. 
     Cell phone technology was being used by billions of people and it was confined to a small screen. And there was a need for having a better infrastructure of 2G to 3G improved the technology where people could stream video. 
     We saw people were not enjoying the mobile entertainment. Now people will be apple to watch a video. We are solving the problem of people looking to a small screen, since they can enjoy the mobile entertainment to the fullest, And this will allow business people to be able to make presentations on the fly. This also people enjoy taking picture using their cell phones and what is the use of having a picture that need to be uploaded to a laptop in order to see a bigger size of it. People now using the projector phone do not have to carry the laptop and a project and take with them everywhere they go, all they need to carry is the projector phone anywhere they go. Impromptu presentation. 
     The phone is dual sim card phone and is compatible with Quad Band and can be used anywhere in the work. The phone has two sim cards slots since now you can have two accounts one for business and for personal solving the problem of people carrying two phones around. Also allowing having two carriers phone on the same phone. We also have a FM antenna for people to watch Analog TV or listen to FM radio where the services are available. The phone also has a microSD card slot where people can load a microSD card. Where people can upload content to the phone or save from the phone to the card. 
     The phone has two cameras a front camera and a back camera allowing people to record videos with sound and save them to be projected later. The front camera can be used for video conferences. Or as a web camera and attached to a computer. The phone also has touch screen to help with an easy to use interface design. For people being able to touch the icons on the screen to access the content inside the phone. The phones&#39;s keypad has backlighting so people can be able to see the buttons in a dark room. The phone use a mini usb port which is a global standard to connect the phone or to a computer device, i.e. Ipod, DVD Players, Game Consoles. Software can change the projector from normal screen to wide screen with one click of a button. The phone is small enough to be carried by a regular carrying case using the belt of the carrier. 
     We are using a very economical processor with amazing processing capabilities in its price range GPRS  12 , best cost effective processor for a media phone, it has an excellent GPRS throught and excellent power conservation and is very stable with Operating Systems, Lynux and C based operating systems. And will work with any Operating system. The keyboard is an easy to use number pad keyboard and has talk buttons for projection and has hot buttons to interact with display screen. The keyboard has a joypad for easy navigation within the screen and while the phone is in projection mode. During a projection session if a call comes in it will be visible on the screen or the projection. 
     The phone uses a 1200 mAH battery that with a full charge can give 2 to 3 hrs of talk time and up to 1.5 to 2 hours of projection time. 
     Examples of LCD projectors are described in the following documents: 
     U.S. Pat. No. 5,012,274 which was issued to Dolgoff on Apr. 30, 1991, described an active matrix LCD light valve between crossed polarizers, utilizing individual transistors to control each “pixel area” of the LCD and storage elements to store signal data for each pixel, with optically shielded “dead spaces” between pixels to eliminate electric field crosstalk. 
     U.S. Pat. No. 5,122,870 which was issued to Takeda on Jun. 16, 1992 described projection type liquid crystal color display apparatus has three liquid crystal display panels which are the same in structure. 
     U.S. Pat. No. 4,973,154, which was issued to Miyatake on Jul. 24, 1990 described projection display apparatus has a light source, a component color separator, a light transmitter(s), three light valves, a light combiner, a single projection lens, and a drive circuit. 
     U.S. Pat. No. 5,233,338, which was issued to Nguyen on Aug. 3, 1993 described a color sequential liquid crystal display, such as a television display, includes a lattice of selectably settable pixel elements which are time multiplexed addressed and illuminated during addressing to produce sequential red green and blue light outputs in any display period. 
     U.S. Pat. No. 5,847,748. which was issued to Laughlin on Dec. 8, 1998 described A multimedia projection system which includes a notebook computer and an integral projector. The system includes a base portion containing a central processing unit and a user input device, such as a keyboard. 
     U.S. Pat. No. 5,905,540 which was issued to Miyashita on May 18, 1999 described a projection-type video display in which the entire input video signal is first digitally corrected through digital gamma correction. Then, a subset of the corrected video signal is corrected again through analogue correction techniques. 
     U.S. Pat. No. 6,774,868 which was issued to Bowen on Aug. 10, 2004 described a method for tiling multiple displays to generate a large area display of moving data. Specifically, one embodiment of the present invention includes a system for generating a large area display of moving data. 
     U.S. Pat. No. 7,161,573 which was issued to Takatori on Jan. 9, 2007 described a method for driving a liquid crystal display apparatus in which in each field, scan lines are successively scanned in order to display an image, the scanning sequence or the polarity of a signal voltage is reversed between a first field and a second field. 
     U.S. Pat. No. 4,904,061, which was issued to Aruga on Feb. 27, 1990 described a projection-type display device for producing a faithful colored synthesized image based on equating the luminous intensity distributions and light patterns produced by three twisted nematic liquid crystal light valves for three primary color images. 
     SUMMARY 
     In light of the advancements in the telephony industry and in the cell phone industry, The cell phone services in United States are run by large carrier corporations such as Verizon, Sprint, AT&amp;T and T-Mobile which together comprise over 95% of the market share. In turn, customers are forced into long term contracts and offered out dated phones into the U.S. market compared to what is available in Asia and Europe. New technology enters the market at a very slow pace so carriers can eliminate the large stocks of phones that they buy through Nokia, HTC, LG, Apple, Samsung etc. 
     Our method is smart projector phones that are quad band and openly compatible with AT&amp;T, T-Mobile, or any other GSM provider worldwide. We seek to take advantage of the technology lag between what is offered in the U.S. and what is currently available overseas. 
     Advantages: 
     New energy-efficient Smart Phones with built in pico (pocket) projectors 
     Quad band GSM technology that makes the phone useable on frequencies worldwide and compatible with any GSM company.
