General Description

This LCD TV monitor using FL-1 platform. It can support PC analog signal ( via 15 pin D-Sub input ) and TV signal. It support PIP

function that is TV picture on PC graphic or TV picture on DVI /HDCP. It’s output resolution is up to 1366X768 75Hz for WXGA panel.

It can support DVI HDCP digital signal input and also support TV (RF) , CVBS/ RG B signal ( from SCART1 I/O for Europe model ) , CVBS / YC ( from SCART2 I/O for Europe model ) , CVBS/YPbPr ( from Cinch I/O for Non-Europe model ) , CVBS/YC ( from Cinch and S terminal I/O for Non-Europe model ) , and also have side I/O , support CVBS/YC and Headphone for User easy used .

And It can also support Y Pb Pr signal input (from Cinch I/O) for 480I, 480P, 720P, 1080i 60Hz and 576I, 576P, 720P, 1080I 50Hz HDTV format input.

Note : For Chinch I/O model two components input is provided one for 480I,480P and 576I, 576P the other for the 480I, 480P, 720P,

1080i 60Hz and 576I, 576P, 720P, 1080I 50Hz HDTV format input.

It also have PVR output function , support and monitor all the CVBS signal output with L/R sound.

This LCD monitor TV use MST51512 as Scaler engine, which has embedded Analog D-sub, digital DVI decoder, scaling input signal for panel, OSD and simple 3D de-interlace. The extra SDRAM is to accomplish video frame rate conversion and PIP function.

The external CPU can be used for back light control, RC receiver, keypad input, I/O switch control , IIC communication and TV tuning control, MSP34XX sound decoder control, SAA7119 video decoder control , Columbus IC ( 3D- comb filter ) control , and Audio AMP TPA3004D sound control .

Video decoder SAA7119 is used for TV video processing and convert it with CCIR 601/16bits or 656/8bits digital format and send to Columbus IC for 3D comb filter processing and noise reduction processing , after that then send to Scaler for de-interlace process.

One audio decoder MSP34XXG is used for TV sound processing, and output to Class D audio amplifier TPA3004D , then we can have 2 X10W audio output .

In Nafta model CC,V-chip data is decoded in SAA7119 and the scaler OSD display the CC information. The V-Chip is decode by SAA7119 and control via the MCU. In Europe model "Teletext display". Data decode is done by SAA5360, output RGB/FB is to video decoder input for text overlapping. In non-text model( Nafta. Etc.), this chip is Not used .

Go to cover page

MM tuner is used to receive RF wave and output CVBS and 2nd IF signal. CVBS is to video decoder (SAA7119) for color process, 2nd IF is to sound decoder (MSP34x5) for audio process. The tuner control is via IIC ex. channel tuning. For different TV system, tuner and sound decoder have diversity as above. Standard TV input (Tuner, S-video, CVBS, SCART) is processed by SAA7119, But YPbPr, SDTV and HDTV(480i, 576i, 480p,576p,720p,1080i), is done by scaler MST51512L/502L ADC. But the signal is still link to SAA7119 if PIP (video in graph) function is requested. Then all YPbPr signal processed by SAA7119 could be the PIP video source. (* May use down sampling in HD0) MV protect is decoded by scaler. Video decoder SAA7119, is in charge of color decoding, could support PAL, NTSC and SECAM world wide system. Compare to SAA7118, SAA7119 improve some picture quality, like V-chip CC I2C read-back, LTI, CTI, skin tone correction(see task A), also the HD0 is supported, so if F1 need PIP function then the The Teltext function is for WE model, need a extra IC SAA5360. CVBS input, R/G/B, FB, out. Due to the SAA5360 request input signal 1Vrms and only one input channel, so the CVBS input source is from SAA7119 AOUT (CVBS out with 1Vrms). The R/G/B FB output into SAA7119 by AI22/AI32/AI42, and AI44 could overlay on any video source. Sound decoder MSP3415/45 is responsible to sound decode of tuner 2nd IF. It has one 2nd IF, two selectable audio sources input. And one loudspeaker, one scart out. Due to the input port limitation, a MUX is added for AV source select( PC audio in is fix in SC1). If the post audio amplifier is gain fixed type then the volume adjust will be on MSP34x5. Scaler MST51502L/51512L besides scaling function, PIP, 3D de-interlacer, color enhance are major feature. Even de-interlacer is not so good but for static picture is enough to avoid image sticking. In America market, to avoid patent issue, two SDRAM is necessary for graph frame buffer. But in else region one SDRAM is enough. Of course, if no PC mode in spec, then one SDRAM for all model. The scaler structure limitation, the PIP source only from video port,8bitsor16bits. The sub window /PIP size can enlarge to half screen. MCU, NT68F632AL, is 128K flash ROM inside. Power control, RC5 I/O, and key function all done by here. All chip communication is by IIC (SDA/SCL), and ISP is via DDCIIC, but if PC mode un-supported, then a reserved 6pin connector is for same application.

LCD Monitor Quality and Pixel Policy

The TFT monitor uses high-precision technology, manufactured according to HP standards, to guarantee

trouble-free performance. Nevertheless, the display may have cosmetic imperfections that appear as small

bright or dark spots.

This is common to all LCD displays used in products supplied by all vendors and is not specific to the HP LCD.

These imperfections are caused by one or more defective pixels or sub-pixels.

1. A pixel consists of one red, one green, and one blue sub-pixel.

2. A defective whole pixel is always turned on (a bright spot on a dark background), or it is always off (a dark spot

on a bright background). The first is the more visible of the two.3. A defective sub-pixel (dot defect) is less

2. visible than a defective whole pixeland is small and only visible on a specific background.The HP display does

not have more than:

4. bright dots.

5. dark dots.

6. total bright and dark dots.

7. No more than two adjacent (less than 2.5 mm edge-to-edge) defective pixels. To locate defective pixels, the monitor

should be viewed under normal operating conditions, in normal operating mode at a supported resolution and

refresh rate, from a distance of approximately 50 cm (16 in.).HP expects that, over time, the industry will continue to

improve its ability to produce LCDs with fewer cosmetic imperfections And HP will adjust guidelines as

improvements are made.

DDC Instructions

Configuration and procedure

There is no Hardware DDC (DDC IC) anymore. Main EEPROM stores

all factory settings and DDC data (EDID code) which is also called Software DDC. The following section describes the connection and procedure for Software DDC application. The main EEPROM can be reprogrammed by enabling '' factory memory data write'' function on the DDC program (EDID46.EXE).

Initialize alignment box

In order to avoid that monitor entering power saving mode due

to sync will cut off by alignment box, it is necessary to initialize

alignment box before running programming software

(EDID46.EXE). Following steps show you the procedures and

connection.
