Abstract
A mobile information communication apparatus includes a data processing device for sending plotting command/data to a display control device that controls the pixels of a display panel belonging to the mobile information communication apparatus. An interface device is provided which receives the plotting command/data generated by the data processing device and sends, based on plotting command/data, an external display signal to the external display device. The data processing device and the interface device are configured to send, from the interface device, a higher-resolution external display signal.
Claims10
A mobile information processing apparatus, comprising:
- a display means including a display panel having a screen on which an image is displayed as a result of an activation of pixels, and a display control means which controls the activation of the pixels of the screen of the display panel;
- an interface means capable of being connected to a peripheral device, the peripheral device including an external display means or the peripheral device being connected to the external display means;
- and
- a data processing means which (i) processes image data and (ii) performs at least one of (a) a first function of generating a first digital display signal based on the processed image data, and sending the first digital display signal to the display control means, the first digital display signal having a same resolution as a resolution of the screen of the display panel and (b) a second function of generating a second digital display signal based on the processed image data, and sending the second digital display signal to the interface means, the second digital display signal having a higher resolution than the resolution of the screen of the display panel.
A mobile information processing apparatus, comprising:
- a display means including a display panel having a screen on which an image is displayed as a result of an activation of pixels, and a display control means which controls the activation of the pixels of the screen of the display panel;
- an interface means capable of being connected to a peripheral device, the peripheral device including an external display means or the peripheral device being connected to the external display means;
- and
- a data processing means including a central processing circuit which processes image data, and a graphic controller which writes bit-mapped data to a single VRAM based on the processed image data,
- wherein the graphic controller performs at least one of (i) a first function of reading first bit-mapped data of an image having a same resolution as a resolution of the screen of the display panel from the VRAM, generating a first digital display signal that conveys the read first bit-mapped data, and sending the first digital display signal to the display control means, and (ii) a second function of reading second bit-mapped data of an image having a higher resolution than the resolution of the screen of the display panel from the VRAM, generating a second digital display signal that conveys the read second bit-mapped data, and sending the second digital display signal to the interface means.
A graphic controller which is installed in an information processing apparatus including (i) a display means including a display panel having a screen on which an image is displayed as a result of an activation of pixels, and a display control means which controls the activation of the pixels of the screen of the display panel, (ii) an interface means capable of being connected to a peripheral device, the peripheral device including an external display means or the peripheral device being connected to the external display means, and (iii) a data processing means including a central processing circuit which processes image data,
- wherein the graphic controller writes bit-mapped data to a single VRAM based on the image data processed by the data processing means, and
- wherein the graphic controller performs at least one of (i) a first function of reading first bit-mapped data of an image having a same resolution as a resolution of the screen of the display panel from the VRAM, generating a first digital display signal that conveys the read first bit-mapped data, and sending the first digital display signal to the display control means, and (ii) a second function of reading second bit-mapped data of an image having a higher resolution than the resolution of the screen of the display panel from the VRAM, generating a second digital display signal that conveys the read second bit-mapped data, and sending the second digital display signal to the interface means.
