6.3.1.4.4 Multiple Pulse Heights to Increase Bit Depth
With the TPS99000-Q1, up to four sets of photo feedback threshold settings are supported within a given sequence. This is useful in a discontinuous operation to create smaller sub-LSB bits (bits that are smaller than the normal LSB).
The LED_SEL(3:0) lines are encoded to include group information as well as color selection (and blanking current selection).
Each group can be defined to determine different behaviors for specific color bits. For example, Group 0 can be used for LSB, and Group 1 can be used to create LSB-1.
| LED_SEL(3:0) | NAME | ACTION |
|---|---|---|
| "0000" | OFF | Driver Disabled Mode S_EN1 forced high RGB selects low |
| "0100" | R BLANKING | LED_SEL(1:0) - "00"=blanking LED_SEL(3:2): "01"=red "10"=green "11"=blue |
| "1000" | G BLANKING | |
| "1100" | B BLANKING | |
| "0001" | GRP0 RED | Driver Enabled Mode: LED_SEL(3:2) - Define Group: '00' - Group 0 '01' - Group 1 '10' - Group 2 '11' - Group 3 LED_SEL(1:0): "01" - red "10" - green "11" - blue |
| "0010" | GRP0 GREEN | |
| "0011" | GRP0 BLUE | |
| "0101" | GRP1 RED | |
| "0110" | GRP1 GREEN | |
| "0111" | GRP1 BLUE | |
| "1001" | GRP2 RED | |
| "1010" | GRP2 GREEN | |
| "1011" | GRP2 BLUE | |
| "1101" | GRP3 RED | |
| "1110" | GRP3 GREEN | |
| "1111" | GRP3 BLUE |
The group1-3 RGB selections may be used to create fractional LSBs in the sequence, as illustrated in Figure 6-23.
Figure 6-23 Extended LSB Bit Depth in Discontinuous OperationThis feature, combined with the ability to make smaller absolute-size light pulses, provides a method to extend the practical bit depth limit from the typical 6 bits per color, as is the case in legacy systems, to 7 or 8 bits with TPS99000-Q1/DLPC23x-Q1 second-generation systems.
