Abstract
A display control apparatus that controls first and second modulation sections optically connected in series includes a storage unit and a control unit. The storage unit stores information to specify a defective pixel of the first modulation section. The control unit controls the second modulation section in response to a defect of the defective pixel being stored in the storage unit.
Claims11
A display control apparatus that controls first and second modulation sections optically connected in series, the display control apparatus comprising:
- a storage unit that stores information to specify a defective pixel of the first modulation section;
- and
- a control unit that controls the second modulation section in response to a defect of the defective pixel being stored in the storage unit, the second modulation section including at least one of a plurality of color panels and a luminance panel,
- wherein the control unit varies the amount of control responsive to the defective pixel step by step in response to the positional relationship between the defective pixel of the first modulation section and a plurality of pixels of the at least one of the plurality of color panels and the luminance panel, and controls the plurality of pixels which the second modulation section has at a position corresponding to the defective pixel being stored in the storage unit and at positions adjacent to the corresponding position, and
- a state of the defective pixel is not changed prior to or during the compensation;
- the first modulation section including three panels respectively corresponding to different colors;
- the second modulation section includes the luminance panel module modulating the luminances of all wavelength ranges;
- and
- pixels corresponding to the defective pixel included in non-defective panels and the luminance panel compensate for the defective pixel by an amount of compensation determined according to an amount of defect.
A display control method of controlling first and second modulation sections optically connected in series, the method comprising:
- using a storage unit that stores information to specify a defective pixel of the first modulation section;
- controlling the second modulation section in response to a defect of the defective pixel being stored in the storage unit, the second modulation section including at least one of a plurality of color panels and a luminance panel;
- and
- varying the amount of controlling responsive to the defective pixel step by step in response to the positional relationship between the defective pixel of the first modulation section and a plurality of pixels of the at least one of the plurality of color panels and the luminance panel, and controlling the plurality of pixels which the second modulation section has at a position corresponding to the defective pixel being stored in the storage unit and at positions adjacent to the corresponding position,
- wherein a state of the defective pixel is not changed prior to or during the compensation;
- the first modulation section including three panels respectively corresponding to different colors;
- the second modulation section includes the luminance panel module modulating the luminances of all wavelength ranges;
- and
- pixels corresponding to the defective pixel included in non-defective panels and the luminance panel compensate for the defective pixel by an amount of compensation determined according to an amount of defect.
