California Micro Devices has released a new port for the phone display controller

California Micro Devices has introduced a dual display and audio controller, designed to integrate the VESA Standard Mobile Display Digital Interface (MDDI, Mobile Display Digital Interface) link, wireless phone, and with Qualcomm's Mobile Station Modem (Mobile Station Modem, MSM) chipsets compatible.
The new CM5100 is fully compatible with the MDDI based serial client characteristics, is an integrated display with embedded memory controllers can support resolutions up to QVGA (320x240) of the main thin film transistor (TFT) liquid crystal display (LCD ) and resolutions up to QCIF + (176x220) of the auxiliary display. CM5100's unique structure optimized for the current most advanced TFT LCD module, direct integration of the drive for one of the highlights in the glass substrate, and also allows the use of low-cost non-RAM drives for non-integrated display modules. In both cases, compared with competing solutions, CM5100-based solutions will make it in smaller packages, lower costs. Additionally, California Micro Devices to CM5100 also the first MDDI compatible with the integrated audio controller integrated display controller with advanced audio and video synchronization.
CM5100 supports all recommended by the MDDI specification necessary for audio, video and control information packets. Integrated MDDI client transceiver is Type I (internal mode, the connection wires of up to 15cm), by a data line pair, a set of filtering lines on (strobe pair) and a dedicated power line to the composition, can support data rates up to 385Mbps. Thus, in low supply, CM5100 requires only six lines, and the traditional parallel interface may be to control the display contains 60 routes, and other sources.
CM5100 contained within the video imaging devices and integrated structure so that it can be used as buffers with display controller to use, through a standard RGB interface control resolution QVGA main display, CPU control auxiliary class interface "smart" display. Audio packets can also be transmitted through the MDDI pipe and through the I2S interface, transferred to a local stereo audio codec. I2C host interface allows CM5100 with any MDDI interface to allow its control through I2C auxiliary devices.
CM5100 low power process technology development, with a variety of power loss can minimize the different power management modes. CM5100 100-spot, 0.5mm pitch wafer-level chip package, the form factor of only 5.0mm x 5.0mm, is the industry's smallest MDDI based display controller.
Evaluation boards and chip samples of the CM5100 are available now. 1,000-piece quantities start at $ 6 per piece. Mass production scheduled for the fourth quarter of 2006.

Microsoft Windows CE display drivers and hardware

Microsoft Windows CE operating system version 2.0 graphic style had great changes in version 1.0, the graphical design interface (GDI) directly with the display hardware phase, in version 2.0, GDI and one or more connected to the TFT driver , which in turn is connected with the display hardware. The display technology allows Windows CE to use a variety of display devices without the need to code programs for each device has the hardware, the new Windows CE GDI with the purpose of small steps together.
    This paper first consider a good driver with a Windows CE display characteristics, it discusses the display driver device driver should perform the interface functions, the same graphics the original engine level, can be used to simplify the writing display drivers, GDI support equipment driver is also discussed.
    The paper then lists the Windows CE support for the depth of detail in each pixel, display buffer format, and discuss the display hardware, because the display driver is the passage between the GDI and the display device, the display driver hardware support, also need support for GDI.
Windows CE Display Driver
    Like most of the same Windows CE display driver interface (DDI) DDI for Microsoft Windows NT, a subset, if you are not familiar with the Windows NT DDI, in writing of your Windows CE display driver, it should read the Windows NT device driver package display driver section.
    Windows CE Windows NT DDI only the most basic graphics engine and driver functions. Windows CE and Windows NT differences, has the following details:
Windows CE display drivers always have the same function, GDI does not check the driver capability information;
Windows CE display driver does not refuse to complex operations, it transferred its back to the GDI, so that the operation is divided into simple steps, because all Windows CE display driver support the same features, GD can call the display driver first before the decomposition of complex operations .
Windows CE display drivers are compiled into dynamic link libraries (. DLL files) instead of library functions (. LIB file).
    All Windows CE display driver must implement a set of DDI function, which consists of. GDI call to initialize the display driver and the drawing to show, in addition to DDI function, this set of VC + + class, it calls the primary graphics engine (GPE) classes, show drivers use it to make it easier for hardware acceleration, the standard display driver calls GPE classes and acceleration is based on the S3Trio64 display hardware, if your video display hardware uses a different chip, called in a way you can change to suit your GPE hardware capacity.
    Note that using the GPE class is optional, you do not need them to write to your display driver, the cost of the implementation of the DDI function is more complex, note that the GPE classes provided by Microsoft for your display hardware need to have a flat frame (frame) buffer, if your hardware is not shown, for example, it uses a custom window to connect to the removable memory, it may not use the GPE classes, in order to obtain more detailed information, in this article, part of Windows CE display hardware recommendations, Dirty Rec Drivers in particular sub-section.
    Windows CE display drivers are usually in many ways with different device drivers, the main difference is that they are not exposed to I / O interface. Therefore, they can not be Device Manager to manage, so register can never be their call. Result, no special equipment, documents or other file system records and activities to coordinate the display driver, display driver loading mechanism is a display driver to use application software, called with the display driver names function dynamic Create DC link file. This allows Windows CE to load the lcd display driver, and initializes the device context to be able to return to the calling application of the default display driver, of course, is automatically loaded.

DDI function
    The following table lists the display and print the DDI function driver display driver should be listed here show all the implementation of DDI functions. Implementation of all print driver should print DDI function. However, only Drve Enable Drive must show the driver a dynamic link library (DLL) output. Therefore, only DrvEnableDrive must have a name, other functions are free to call, as they returned from the Drr Enable Driver, function pointer output to GDI, no matter who is called, always follow the definitions file in the Win DDI.H prototype.

    These include a liquid crystal display module, panels and LCD TVs, monitors included.
    In this regard, AUO said it will respect the third party intellectual property rights, and hope the third person to respect the intellectual property of AUO, AUO will try to safeguard the interests of the company and customers.
    ITC said that, AUO, BenQ (BenQ), Haier Group, LG Electronics, Sanyo Electric and the U.S. subsidiary of the individual, together with TCL Corp., TTE Technology, Inc., VIZIO, Inc. Mused as defendants, including VIZIO for TV manufacturing giant Amtran reinvestment brand.
    Sharp Jan. 25 announced that it has the U.S. International Trade Commission and the document to the document the United States District Court of Delaware, alleged violations of AUO and its customers 7 U.S. patents, Sharp, AUO allegations of LCD panels produced, LCD drive module and Customers in the U.S. AUO LCD TV, monitors alleged infringement; Sharp asked ITC issued an order prohibiting the infringing products into the United States.
    Panasonic, a subsidiary of Sanyo Electric also announced on January 27, document to the document have been charged with the Tokyo District Court against the company owned by Sharp's four patents related to liquid crystal display technology, in addition to requirements related to Sharp stopped selling the infringing products manufactured and beyond , Sharp also made claims for damages.
    AUO and Sharp is not the first 1 court for patent infringement in 2004, TECO LCD TV by Sharp in Japan against infringement, Sharp was used for TECO LCD TV panels, AUO, AUO to protect customers, TECO interests 2005, reached an agreement with Sharp, AUO, the two sides to expand cross-licensing, followed by Teco violations also ended with the Sharp.
    Analysts believe that this, in the past more than for personal use Sharp panels, but the heavy volume of 10 Generation plant capacity, may present an over-supply, it must be exported to downstream plants, the Sharp, AUO against infringement by the way, can be interpreted as AUO to force about a reconciliation, and secondly also hope before the end of the settlement or litigation, grab AUO downstream order.
