DAEWOO Electronics Co., Ltd. Operational Description of 15inch LCD Monitor L510B (Please, refer to a block diagram attached) 1. Power The part, power supplier of SMPS type, is make DC voltage 3.3V, 5Vs, 5Va, 5Vd, 6.2V, 12V to operate a main board and a inverter from input voltage AC 100~240V of mains network. The DC3.3V & the 6.2V are supply to main board as soon as applied AC 100~240V to this board. And others is supply to a main board after to be detected on-signal from a micro controller. - DC 3.3V is supply into a scaling IC(ASI320)and LCD(LM151M-2)panel. - DC 5Vs is supply into 8-bits micro controller(MTV212MV64U). - DC 5Va is supply into a analog part of ADC IC(TDA8752B). - DC 5Vd is supply into a digital part of ADC IC(TDA8752B). - DC 6.2V is to switch ON-OFF of 3.3V supplied into LCD(LM151M-2) panel. - DC 12V is to generate a AC high voltage to light 4-back light lamp of LCD panel on a inverter. 2. Video Processing (Analog-Digital Converting) The part, ADC IC(TDA 8752B) and around circuit, is convert an analog R, G, B signals applied from a video source into a digital R, G, B data, 8bits each used by a scaling IC(ASI320). A dot clock of the ADC IC, applies to a scalier IC, is max 80MHz, but it is change according to a video resolution and a vertical refresh rate. 3. Video processing (image process) The part, scaling IC(ASI320) and around circuit, is change a resolution applied from a video source into 1024*768 and R, G, B data, 8bits each to display on LCD panel. LCD panel only supports a resolution 1024*768 and vertical refresh, 60Hz~75Hz to display. And then if applied other resolutions, the IC changes a resolution to 1024*768 and controls a frame size to fit a LCD’s needs. 14.318MHz from a crystal and a pixel clock from ADC IC are applied to operate the IC. A panel output interface of the IC is all 48bits wide low voltage TTL type, R, G, B data, 8bits(even-odd) each, And supplies Hsyn(Horizontal frequency), Vsyn(Vertical frequency), Data Enable clock, and pixel clock depending to vertical refresh to LCD panel. 4. Inverter The part only is invert DC 12V to AC 650V to light 4-back light lamp of LCD panel. And, excluding DC 12V from power supplier, supplies On- Off (active high, 5V), and brightness control signal(DC 0V~3V) from a main board. During operating to invert, transformer is switching about 50kHz to generate a AC high voltage. DAEWOO Electronics Co., Ltd. 5. 8-bits micro controller(MTV212MV64U) The part, a micro controller(MTV212MV64U) and around circuit, is control a digital level in the ADC IC, an image scaling in the scaling IC, and power functions as ON-OFF, DPMS by program. And the controller has an I 2 C(SCL, SDA) interface to communicate with ADC IC and a direct- bus to communicate with scaling IC. And an operating clock of the controller is a 12MHz.
