Otherwise the TFT Module may be damaged. (10) At the insertion or removal of the Signal Interface Connector. press at the far ends of the CFL Reflector edge softly.Do Not Copy 2 VG2021m-1 . (11) After installation of the TFT Module into an enclosure (LCD monitor housing. (13) The LCD module contains a small amount of materials having no flammability grade. be sure not to rotate or tilt the Interface Connector of the TFT Module. for example). The LCD module should be supplied with power that complies with the requirements of Limited Power Source (IEC60950 or UL1950). do not twist or bend the TFT Module even momentarily. it should be taken into consideration that no bending/twisting forces may be applied to the TFT Module from outside. or an exemption should be applied for. Instead. When designing the enclosure. Otherwise the TFT Module may be damaged. (12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. (14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950 or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit ViewSonic Corporation Confidential . Incorrect Methods : Surface of the panel is pressed by fingers & this may cause “ MURA “ Take out the monitor with cushion Take out the monitor by grasping the LCD panel. Place the monitor on foreign objects . That could scratch the surface of panel ViewSonic Corporation Confidential .Correct methods : Only touch the metal-frame of the panel or the front cover of the monitor. That may cause “ MURA“.

Resolution Notice allows the user to enable or disable this notice. To further reduce system costs. a high quality display processing engine. The oversampling ADC samples the input RGB signals at a frequency that is much higher than the signal source pixel rate. This can preserve details in the video signal that ordinarily would be lost due to input signal jitter or bandwidth limitations in non-oversampled systems. while eliminating the output end of frame short-line. It is configured with a high-speed integrated triple-ADC/PLL. an integrated DVI receiver.Do Not Copy 13 VG2021m-1 . The TSUM57AK incorporates the world’s first coherent oversampled RGB graphics ADC in a monitor controller system. ViewSonic Corporation Confidential . the TSUM57AK also integrates intelligent power management control capability for green-mode requirements and spread.4.spectrum support for EMI management. and an integrated output display interface that can support RSDS panel interface format. Circuit Description The TSUM57AK is total solution graphics processing IC for LCD monitors with panel resolutions up to SXGA. The TSUM57AK also incorporates a new Dynamic Frame Rate (DFR) generator for the digital output video to the display panel that preserves the advantages of a fixed output clock rate.
