Control Explanation

Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion. Press the [2] button to obtain a sharper image.NOTE: Auto Image Adjust works with most common video cards. If this function does not work on your LCD display, then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.

Contrast adjusts the difference between the image background (black level) and the foreground (white level).

Brightness adjusts background black level of the screen image.

Input Select toggles between inputs if you have more than one computer connected to the LCD Display.

Color Adjust provides several color adjustment modes, including preset color temperatures and a User Color mode which allows independent adjustment of red (R), green (G), and blue (B). The factory setting for this product is 6500K (6500 Kelvin).

sRGB-This is quickly becoming the industry standard for color management, with support being included in many of the latest applications. Enabling this setting allows the LCD display to more accurately display colors the way they were originally intended. Enabling the sRGB setting will cause the Contrast and Brightness adjustments to be disabled.

9300K-Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting).

(a) Circuit operations: In analog signal input to scaling IC, the operation theory is to convert the analog

signals of Red, Green and Blue to the digital signals of Red, Green and Blue. The scaling IC has the internal A/D converter that converts analog signals to digital data.

The scaling IC has OSD and auto detecting input timing functions. OSD offers adjustable functions to the end-users. Auto detecting timing function can detect change modes. It outputs the digital R-G-B data, pixel clock and control signal to TCON of the LCD module. A MCU, build in scaling IC (Genesis GM5862H-LF), is responsible for the system processing. There are two external storing units, one is 24C16 to store the OSD function data and user preset timings and HDCP key content, the other one is flash ROM (25LV040) to store the


22

firmware code. Others, the scalar IC has a I/O port to detect Pivot device whether its level change, once

I/O port level change, the scalar will auto make OSD Menu window disappear. Moreover, when input timing VS over 75Hz, the scalar will along with external SDRAM

memory to do FRC function, and make image can work normally.

(b) IC introduction: 1.) Genesis GM5862H-LF SCALER IC:

Genesis GM5862H with analog (RGB), DVI and HDCP function, and support resolution up to WUXGA. The gm5862H leverages Genesis patented advanced image-processing technology, as well as a proven integrated ADC/PLL and an Ultra-Reliable DVI® compliant digital receiver to deliver a high-quality solution for mainstream dual input monitors. The gm5862H also includes an ITU656 video input port with color space converter that makes it an attractive solution for low cost MFM and TV applications. The output section contains a 24-bit TTL output interface and a dual channel LVDS transmitter for direct interfacing of commercially available LVDS LCD panel modules. In addition, GM5862H includes an integrated X86 OCM with SPI compatible interface, advanced color control features, a multicolor proportional font OSD engine, and a number of system I/O components.

2.) EEPROM: Use 24C16 EEPROM to store monitor user data and user preset timings and

HDCP key. There are 10 user timing modes are automatically saved in it. Each timing mode is allocated with 22 bytes of memory space for information such as Sync frequencies, polarities… etc. PC can access the EEPROM data indirectly through the SDA and SCL channels of DVI and D-sub (IIC communication). The digital and analog DDC data are stored in two 24C02s EEPROM.

3.) Flash: Use 25LV040 flash rom to save firmware program in order that the scalar IC GM5862H can access code from it and deal with it by CPU engine within the scalar.

A-5.) Buck Converter(MCU, USB, Audio, Panel Power section)

Fig.A

Fig.A shows the typical Buck Converter circuit. Q2 s a switching device, and Q1, Q4 are the totem pole which get enough ability to drive P-MOS. When the Gtae of Q2 is low level, Q2 turns on. At high level, Q2 turns off. The pulse waveform will appear at D-terminal of Q2. L1, C5, C6, and D1 will transfer the pulse to stable DC level. The feedback circuit is composed of two resistors R5 and R11, and feedback the DC level 1.25V with error signal. C8 is a compensation capacitor.

A-6.) PWM IC (TL1451)

Fig. 2

The Tl1451AC incorporates on a single monolithic chip all the functions required in the construction of two pulse-width modulation control circuits. Designed primarily for power supply control, the TL1451AC contains an on-chip 2.5V regulator two error amplifiers, an adjustable oscillator, two dead-time comparators, under-voltage lockout circuitry, and dual common-emitter output transistor circuits. The uncommitted output transistors provide common-emitter output capability for each controller. The internal amplifiers exhibit a common-mode voltage range from 1.04V to 1.45V. The dead-time control comparator has no offset unless externally altered and can provide 0% to 100% dead time. The on-chip oscillator can be operated by modulating RT and CT. During low Vcc conditions, the under-voltage lockout control circuit feature locks the outputs off until the internal circuitry is operational.

3. USB Test Procedure A. Introduction

The CATC UHT USB Hub Tester is a modular unit designed for use on the production line to test USB Hubs for proper functionality according to the USB specifications. The UHT tester performs the following tests: 1. hub enumeration 2. hub reset, suspend, and resume operation 3. connection and enumeration of a low-speed device(on each downstream port) 4. data loop-back integrity test with a low-speed device(on each downstream port) 5. connection and enumeration of a full-speed device(on each downstream port) 6. data look-back integrity test with a full-speed device(on each downstream port) 7. individual port suspend and resume operations(on each downstream port) 8. remote wakeup detection and propagation from each of the downstream ports 9. hub-initiated remote wakeup on connect/disconnect events 10. hub over current detection and reporting to the host 11. over current protection(gang or per-port configuration) 12. downstream current restoration(over current removed)

B. System Setup

Position the CATC UHT box on the test bench, near the USB hub to be evaluated. Connect the DC plug of the AC to 5V DC@1000mA power converter to the +5V power receptacle of the CATC UHT box. To activate the unit, plug the AC to DC converter into an appropriate AC power outlet. In the USB test system, connect the CATC UHT box as follow: 1. Connect a USB cable between the upstream port of the USB hub under test and the USB

port of the host PC. 2. Connect a USB cable between the first downstream port to be tested and the USB

connect to labeled “CH1”. 3. Repeat step B for the next ports to be tested, connecting to “CH2”, “CH3”, “CH4” in

sequence. C. Software Installation

Make a copy of the CATC diskette for backup, then copy its contents to the hard drive of the USB-capable PC to be used as the test system host. The UHT software program (usb_uht.exe) is a DOS application and must be run under the DOS operating system. It supports both UHCI and OHCI USB host controller implementations. To run the program, at the DOS prompt, type USB_UHT and press “Enter” key. The program will clear the monitor screen and begin execution. During the test, the program displays the test results on the monitor screen. To terminate the program and get back to the DOS prompt, press any key.
