Display device, control method of display device and electronic apparatus
View Patent ↗A display device includes: a display unit in which pixels including memories are arranged; a memory unit holding data; and a control unit rewriting the contents held by memories concerning pixels belonging to a partial area of the display unit based on data held by the memory unit in accordance with instructions given from the outside.
1. A display device comprising:
a display unit in which pixels including memories are arranged;
a memory unit holding data;
a control unit rewriting the contents held by memories concerning pixels belonging to a partial area of the display unit based on data held by the memory unit in accordance with instructions given from the outside,
wherein the data and the instructions are given in time series in the order of data and the instructions,
the instructions include area information concerning the partial area, and
the instructions include rewrite instruction information indicating rewriting in the partial area; and
a discrimination circuit discriminating the instructions,
wherein the discrimination circuit holds the area information included in the instructions in an area memory and holds the rewrite instruction information included in the instructions in a register.
2. The display device according to claim 1 ,
wherein the control unit performs rewriting control of the partial area based on the area information held by the area memory.
3. The display device according to claim 1 ,
wherein the control unit starts rewriting control of the partial area when receiving the rewrite instruction information held by the register.
4. The display device according to claim 1 , further comprising:
a vertical driver capable of arbitrary selecting respective pixels in the display unit on a pixel row basis.
5. The display device according to claim 4 ,
wherein the vertical driver is configured by a decoder selecting pixel rows belonging to the partial area based on the area information held in the area memory.
6. A control method of a display device including a display unit in which pixels including memories are arranged, and a memory unit holding data, the method comprising:
rewriting the contents held by memories concerning pixels belonging to a partial area of the display unit based on data held by the memory unit in accordance with instructions given from the outside,
wherein the data and the instructions are given in time series in the order of data and the instructions,
the instructions include area information concerning the partial area, and
the instructions include rewrite instruction information indicating rewriting in the partial area; and
discriminating the instructions, wherein the discriminating includes holding the area information included in the instructions in an area memory and holding the rewrite instruction information included in the instructions in a register.
7. An electronic apparatus comprising:
a display device including
a display unit in which pixels including memories are arranged,
a memory unit holding data, and
a control unit rewriting the contents held by memories concerning pixels belonging to a partial area of the display unit based on data held by the memory unit in accordance with instructions given from the outside,
wherein the data and the instructions are given in time series in the order of data and the instructions,
the instructions include area information concerning the partial area, and
the instructions include rewrite instruction information indicating rewriting in the partial area; and
a discrimination circuit discriminating the instructions,
wherein the discrimination circuit holds the area information included in the instructions in an area memory and holds the rewrite instruction information included in the instructions in a register.
8. The display device according to claim 1 , wherein the data is inputted from the outside in an asynchronous state with respect to a vertical synchronization signal.
9. The display device according to claim 1 , wherein the data is to be rewritten concerning pixels belonging to the partial area.
10. The electronic apparatus according to claim 7 , wherein the data is inputted from the outside in an asynchronous state with respect to a vertical synchronization signal.
11. The electronic apparatus according to claim 7 , wherein the data is to be rewritten concerning pixels belonging to the partial area.
12. The electronic apparatus according to claim 7 , wherein the control unit performs rewriting control of the partial area based on the area information held by the area memory.
13. The electronic apparatus according to claim 7 , wherein the control unit starts rewriting control of the partial area when receiving the rewrite instruction information held by the register.
14. The electronic apparatus according to claim 7 , further comprising:
a vertical driver capable of arbitrary selecting respective pixels in the display unit on a pixel row basis.
15. The electronic apparatus according to claim 14 , wherein the vertical driver is configured by a decoder selecting pixel rows belonging to the partial area based on the area information held in the area memory.
16. The method according to claim 6 , wherein the data is inputted from the outside in an asynchronous state with respect to a vertical synchronization signal.
17. The method according to claim 6 , wherein the data is to be rewritten concerning pixels belonging to the partial area.
18. The method according to claim 6 , wherein the rewriting of the contents comprises a rewriting control of the partial area based on the area information held by the area memory.
19. The method according to claim 6 , wherein the rewriting of the contents comprises a rewriting control of the partial area when receiving the rewrite instruction information held by the register.
20. The method according to claim 6 , further comprising:
arbitrarily selecting, by a vertical driver, respective pixels in the display unit on a pixel row basis, wherein the vertical driver is configured by a decoder selecting pixel rows belonging to the partial area based on the area information held in the area memory.
