22) RESOLUTION SETTING (TRES) (R61 H )

This command defines resolution setting.

HRES[9:3]:

Horizontal Display Resolution (Value range: 01h ~ 64h)

VRES[9:0]:

Vertical Display Resolution (Value range: 001h ~ 258h)

Active channel calculation, assuming HST[9:0]=0, VST[9:0]=0:

Gate:

First active gate = G0;

Last active gate = VRES[9:0]

1

Source: First active source = S0;

Last active source = HRES[9:3]*8

1

Example: 128 (source) x 272 (gate), assuming HST[9:0]=0, VST[9:0]=0

Gate:

First active gate = G0,

Last active gate = G271; (VRES[9:0] = 272, 272

1= 271)

Source: First active source = S0,

Last active source = S127; (HRES[9:3]=16, 16*8

1 = 127)

23) GATE /SOURCE START SETTING (GSST) (R65 H )

This command defines resolution start gate/source position.

HST[9:3]:

Horizontal Display Start Position (Source). (Value range: 00h ~ 63h)

VST[9:0]:

Vertical Display Start Position (Gate). (Value range: 000h ~ 257h)

Example : For 128(Source) x 240(Gate)

HST[9:3] = 4 (HST[9:0] = 4*8 = 32),

VST[9:0] = 32

Gate:

First active gate = G32 (VST[9:0] = 32),

Last active gate = G271 (VRES[9:0] = 240, VST[9:0] = 32, 240-1+32=271)

Source: First active source = S32 (HST[9:0]= 32),

Last active source = S239 (HRES[9:0] = 128, HST[9:0] = 32,128-1+32=239)
