Claims (7)

A display device comprising a display area in which a plurality of pixels are arranged, and for controlling each of the plurality of pixels to be turned on or off for each of a plurality of subfields obtained by dividing one field,
A plurality of compression tables are stored, and each of the plurality of compression tables stores a gradation to be displayed and a compression code pattern obtained by compressing a code pattern instructing turning on or off for each of the plurality of subfields. Table storage means for
Compression table selection means for selecting a compression table stored in the table storage means;
Decompression means for decompressing the compressed code pattern of the table selected by the table selection means to generate a restoration table that associates the code pattern with a gradation to be displayed;
Data conversion means for generating a code pattern corresponding to the gradation to be displayed with reference to the restored table based on the image signal indicating the gradation to be displayed;
Display control means for displaying an image in the display area based on the code pattern generated by the data conversion means ,
The code pattern includes a code pattern for designating lighting or extinction for all the corresponding subfields, and a code pattern for designating mixed lighting or extinction for the corresponding subfields.
A display device characterized by that . The code pattern is
A first code part that specifies lighting for all of the corresponding subfields, and the number of corresponding subfields is variable;
A second code part in which corresponding subfields are specified to be lit or extinguished, and the number of corresponding subfields is fixed;
The display device according to claim 1, further comprising: a third code portion that designates turning off for all of the corresponding subfields, and the number of the corresponding subfields is variable. The compressed code pattern is:
A part representing the number of subfields corresponding to the first code part or the third code part in binary number;
The display device according to claim 2, further comprising: a subfield corresponding to the second code portion including a portion in which lighting or extinguishing is represented by a binary number. Temperature acquisition means for acquiring the temperature of the display area;
Each of the plurality of compression tables is associated with a temperature,
The display device according to any one of claims 1 to 3, wherein the selection unit selects a compression table corresponding to the temperature acquired by the temperature acquisition unit. The selection means selects at least two compression tables;
The decompression means decompresses at least two selected compression tables to generate at least two restoration tables;
The data conversion means selects one of the at least two restoration tables according to a predetermined rule, and displays the selected restoration table with reference to the selected restoration table based on an image signal indicating a gradation to be displayed. The display device according to any one of claims 1 to 3, wherein a code pattern corresponding to a power gradation is generated.   The display device according to claim 1, wherein the plurality of subfields are obtained by equally dividing the one field in terms of time.   An electronic apparatus comprising the display device according to claim 1.
