1. Precautions and Safety Notices

1. Appropriate Operation (1) (2) (3) (4) (5) (6) (7) (8) (9) Turn off the product before cleaning. Use only a dry soft cloth when cleaning the LCD panel surface. Use a soft cloth soaked with mild detergent to clean the display housing. Disconnect the power plug from AC outlet if the product is not used for a long period of time. If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off. Do not touch the LCD panel surface with sharp or hard objects. Do not place heavy objects on the LCD display, video cable, or power cord. Do not use abrasive cleaners, waxes or solvents for your cleaning. Do not operate the product under the following conditions: - Extremely hot, cold or humid environment. - Areas susceptible to excessive dust and dirt. - Near any appliance generating a strong magnetic field. - Place in direct sunlight.

2. Caution No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly familiar with all of the following safety checks and servicing guidelines. 3. Safety Check Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage is exposed in such areas as the associated transformer circuits. 4. Power Supply Requirements The external AC power operating range shall be from 90 to 264Vac 5. LCD Module Handling Precautions 5.1. Handling Precautions (1) Since front polarizer is easily damaged, pay attention not to scratch it. (2) Be sure to turn off power supply when inserting or disconnecting from input connector. (3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots. (4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth. (5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. (6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth when handling. (7) Do not open nor modify the Module Assembly. (8) Do not press the reflector sheet at the back of the module to any directions. (9) In case if a Module has to be put back into the packing container slot after once it was taken out from the container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may be damaged. (10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the Interface Connector of the TFT Module. (11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may be damaged. (12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local ordinances or regulations for disposal. (13) Small amount of materials having no flammability grade is used in the LCD module. The LCD module should be supplied by power complied with requirements of Limited Power Source (IEC60950 or UL1950), or be applied exemption. (14) The LCD module is designed so that the CFL in it is supplied by Limited Current

The sync-processor can deal with Separate-Sync, Composite-Sync, and Sync-On-Green. And the PLL can generate very low jitter clock from HS to sample the analog signal to digital data. Input data is latched within a capture window defined in registers refer to VS and HS leading edge. RTD also has 2 ADC input, we can switch these 2 input to choose which input we want to present on RTD embedded LCD monitor. RTD has a YPbPr input, we can connect DVD or some devices that has YPbPr input, YPbPr input can be 1st or 2nd ADC pins. TMDS Input RTD integrates high-speed single link receiver function. It can operate up to 165 M at long cable. RTD integrates an equalizer to enhance the cable loss weakness in long cable application and the advanced tracking algorithm to have better performance in DVI RX. Display Output Timing The display output port sends single/double pixel data transfer and synchronized display timing to an external device. The display port also support display panel with 6-bit per color, turn on the dithering function to enhance color depth. In single pixel output mode, single pixel data (24-bit RGB) is transferred to display port A on each active edge of DCLK, the rate of DCLK is also equal to display pixel clock. The sync & enable signals are also sent to display port on each active edge of DCLK. In double pixel output mode, double pixel data (48-bit RGB) is transferred to display port A & B on each active edge of DCLK and the rate of DCLK is equal to half display pixel clock at this moment. The sync & enable signals are also sent to display port on each active edge of DCLK. Color Processing Digital color R & G & B independent channel sRGB, contrast, brightness, gamma, dithering controls are built in RTD. sRGB compliance function is provided with 9 multipliers. The contrast control is performed a multiply value from 0 to 2 for each R/G/B channel. The brightness control is used to set an offset value from ­512 to +511 also for each R/G/B channel. Also RTD provided 10 bit gamma and a high performance dithering function. Build-In OSD The detailed function-description of build-in OSD, please refer to the application note for RTD embedded OSD. Color LUT & Overlay Port The following diagram presents the data flow among the gamma correction, dithering, overlay MUX, OSD LUT and output format conversion blocks. Auto-Adjustment There are two main independent auto-adjustment functions supported by RTD, including auto-position & auto-tracking. The operation procedure is as following;

VX2235wm-3

Auto-Position 1. Define the RGB color noise margin: When the value of color channel R or G or B is greater than these noise margins, a valid pixel is found. 2. Define the threshold-pixel for vertical boundary search 3. Define the boundary window of searching for horizontal boundary search. 4. Start auto-function. 5. The result can be read from register. Auto-Tracking 1. Setting the control-registers for the function (auto-phase, auto-balance) according to the Control-Table. 2. Define the Threshold 3. Define the boundary window of searching for tracking window. 4. Start auto-function. 5. The result can be read from register PLL System Inside the RTD, there are four PLL systems for display clock and ADC sample clock (PLL1, PLL2,M2PLL, DPLL ). DCLK PLL DPLL frequency = F_IN * DPM / DPN * Divider. F_IN is input crystal frequency. DPM and DPN is in DPLL_M and DPLL_N. DPLL_N, and it divide PLL frequency by 1, 2, 4 or 8. According to parameter DPN, you must set LPF Mode in DPLL_WD. If LPF Mode is 1, the charge pump current, Ich, must be DPM/17.6, while Ich must be DPM/1.67 if LPF Mode is 0. The charge pump current Ich is in DPLL_CRNT. Spread-Spectrum function is also build in DCLK to reduce EMI. You can control the SSP_I, SSP_W, and FMDIV to fine-tune the EMI. M2PLL is a PLL used to power-on reset, FIFO clock and Internal crystal clock. After power-on reset, M2PLL output 10 times frequency of crystal clock. According to crystal frequency, set M2PLL to keep FIFO clock frequency between 240MHz and 250MHz. ADC Pixel Sampling PLL The input pixel sampling PLL of RTD compose of PLL1 and PLL2 and DDS, the hybrid PLL system inherently has a process-independent advantages comparing with pure analog PLL, DDS synthesizer is in charge of the phase-frequency control, PLL1 provided a high frequency to get a larger bandwidth letting the system fast locking, PLL2 finally synthesize the desired pixel sampling clock. The block diagram shown below describes our high-performance tracking system. Host Interface Parallel/Serial Port Determination: After RESET end, the status of pin 5 (TMDS_TST) can be sensed to determine the interface mode: high for parallel port, low, low for serial port. Host Interface Location Determination: After the falling edge of RESET signal, the status of pin 3 can be sensed to determine the host interface location: high for 112-115,118,119, and low for 52-57 Reset Output We have the RESET_OUT function, and also reserve the RESET_IN function. By the bounding of internal pins we can select two kinds of reset function. First of all is only reset-out, we can output the reset signal to MCU, and the MCU can reset the RTD by firmware. The second is RTD output reset and also reset itself. Notice that the reset output is positive polarity, besides, the reset output is open-drain pin, please don't forget to attach a pull-up resistor (10K). The reset function for 3.3V operating voltage detection is determined by 33VRST_REF voltage, No matter 5V or 3.3V MCU is been used, divider the input voltage on 33VRST_REF to 2.2V for internal power sensing circuit detecting, the divider resistor should be 10K level avoiding current leakage. The Programmable Schmitt Trigger of HSYNC To get better waveform of the input HSYNC, we have a programmable Schmitt Trigger circuit. For different HSYNC amplitude and polarity, we can select different setting of the threshold voltage. The Vt + and the Vt - can be selected by register CR97 We can select the old mode or the new mode. When using the new mode we can directly determine the positive threshold voltage (1.4V, 1.6V... 2.6V), and we can choose the hysterias from the Vt + to determine the Vt - (0.6V, 0.8V, 1.0V, 1.2V). We also can finely tune the voltage by minus 0.1V. For application, we can select different threshold voltage by the polarity of the HSYNC. The control register is CR97

Improvements to previous generation devices include: dc volume con-trol, lower supply current, lower noise loor ,higher efficiency, smaller packaging, and fewer external components. Most notably, a new filter-free class-D modulation technique allows the TPA2008D2 to directly drive the speakers, without needing a low-pass output filter consisting of two inductors and three capacitors per channel. Eliminating this output filter saves approximately 30% in system cost and 75% in PCB area. The improvements and functionality make this device ideal for LCD projectors, LCD on itors ,powered speakers, and other applications that demand more battery life, reduced board space, and functionality that surpasses currently available class-D devices. A chip-level shutdown control limits total supply current to 1 µA, making the device ideal for batTery powered applications. Protection circuitry in-creases device reliability: thermal and short circuit. Under voltage shutdown saves battery power for more essential devices when battery voltage drops to low leve.
