HX8347-D(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver6. Display Data GRAMDATA SHEET Preliminary V01The display data RAM stores display dots and consists of 1,382,400 bits (240x18x320bits). There is no restriction on access to the RAM even when the display data on thesame address is loaded to DAC. There will be no abnormal visible effect on thedisplay when there is a simultaneous Panel Read and Interface Read or Write to thesame location of the Frame Memory.6.1 Display data GRAM mappingEvery pixel (18-bit) data in GRAM is located by a (Page, Column) address (Y, X). Byspecifying the arbitrary window address SC, EC bits and SP, EP bits, it is possible toaccess the GRAM by setting RAMWR or RAMRD commands from start positions ofthe window address.(00,00)H (00,01)H (00,02)H --------- (00,EC)H (00,ED)H (00,EE)H (00,EF)H(01,00)H (01,01)H (01,02)H --------- (01,EC)H (01,ED)H (01,EE)H (01,EF)H(02,00)H (02,01)H (02,02)H --------- (02,EC)H (02,ED)H (02,EE)H (02,EF)H(03,00)H (03,01)H (03,02)H --------- (03,EC)H (03,ED)H (03,EE)H (03,EF)H(04,00)H (04,01)H (04,02)H --------- (04,EC)H (04,ED)H (04,EE)H (04,EF)H(05,00)H (05,01)H (05,02)H --------- (05,EC)H (05,ED)H (05,EE)H (05,EF)H---------------------------------(13A,00)H (13A,01)H (13A,02)H --------- (13A,EC)H (13A,ED)H (13A,EE)H (13A,EF)H(13B,00)H (13B,01)H (13B,02)H --------- (13B,EC)H (13B,ED)H (13B,EE)H (13B,EF)H(13C,00)H (13C,01)H (13C,02)H --------- (13C,EC)H (13C,ED)H (13C,EE)H (13C,EF)H(13D,00)H (13D,01)H (13D,02)H --------- (13D,EC)H (13DED)H (13D17E)H (13D,EF)H(13E,00)H (13E,01)H (13E,02)H --------- (13E,EC)H (13E,ED)H (13E,EE)H (13E,EF)H(13F,00)H (13F,01)H (13F,02)H --------- (13F,EC)H (13F,ED)H (13F,EE)H (13F,EF)H----------------Table 6.1 GRAM address for display panel position----------------Himax ConfidentialThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.53-March, 2009
