Embodiment Construction

[0027] Usually, the size of the picture depends on the resolution and color depth. Resolution is the total number of pixels, which is the product of the image height in pixels and the image length. Also, color depth is the number of colors displayed in an image, and it depends on the number of bits per pixel. Thus, for a given number of bits b per pixel, the color depth can be calculated as 2b. As an example, for a black and white image, the number of bits per pixel is 1, so the resulting number of colors is 2. With an increase in bits per pixel, true color with a color depth of 224 (approximately 16 million) can be achieved with 24 bits per pixel.

[0028] The size of the image can then be calculated as the product of the number of bits per pixel and the number of pixels. For example, a QVGA display with a resolution of 240·320 pixels and a color depth of 18 would have a RAM size of 240·320·18 = 1382400 bits corresponding to 172.8 kilobytes.

Abstract

The invention relates to a display for a mobile terminal for wireless communication comprising a first display area (2) with a high colour depth and a second display area (3) with a low colour depth. The invention further relates to a method for a display for a mobile terminal for wireless communication.

Description

technical field [0001] The invention relates to a display of a mobile terminal for wireless communication. The invention also relates to a method for a display of a mobile terminal for wireless communication. In particular, the invention relates to the problem of displaying images on source constrained devices such as mobile terminals. Background technique [0002] Displays in mobile terminals used for wireless communications, such as mobile phones, pagers, personal digital assistants, electronic organizers (organisers), smartphones, etc., sometimes have associated memory (RAM) to store images displayed on the display . The size of the image and therefore the size of the RAM depends especially on the color depth of the image. Therefore, in order to display an image with a high color depth, a large RAM must be implemented in the mobile terminal for the display, so there is a large enough RAM to store the displayed image. [0003] A disadvantage of adapting the size of RAM...
