Problems solved by technology

[0016] As mentioned above, the display unit driving method of the conventional mobile communication terminal is to use the method of displaying line by line from the upper left end of the display unit to the bottom end, so there is a problem that if the screen data is displayed by using the transmission rate control method of allocating bits, then , the beginning part, i.e., the upper left part, has enough bits allocated, so the image quality is good, but the middle area and the lower part are relatively low in quality due to insufficient bits, which cannot maintain the image quality of the more visually sensitive middle area. In the best state, so the perceived picture quality is relatively low

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] FIG. 4 is a conceptual diagram showing an output sequence of a row drive unit in an embodiment of the present invention by dotted lines on a display unit. As shown in the figure, the first displayed line is the center line of the display unit, and two lines are sequentially driven simultaneously to output an image frame.

[0027] In the 176×240 display screen, a dual scanning method in which two rows are provided to the column driver in the vertical direction of the central area in each horizontal period, and the row driver simultaneously drives the two rows will be described below.

[0028] That is, in one scan performed by the row driver, the row address is shifted from 78H to 00H, and in the other scan, the row address is shifted from 79H to EFH.

[0029] At this time, instead of merely changing the output of the row driver for allowing displa...

Abstract

A method for driving a display unit of a mobile communication terminal is provided to improve image quality by supplying screen data to a middle region of a screen in advance. According to the method for driving a display unit of a mobile communication terminal with a column driver and a row driver in order to display screen data in case of transmission rate control, screen data having bit allocation priority in a screen middle region is provided to the column driver by two lines up and down from a screen center line. An output pulse of the row driver is output to two lines up and down from a display unit center line to coincide with the provided screen data.

Description

technical field [0001] The present invention relates to a method for driving a display part of a mobile communication terminal. When the image quality of a display image fluctuates due to transmission rate control, an image frame is displayed from a visually sensitive middle area of ​​the display part to improve the image quality of the middle area of ​​the display part, thereby Can visually improve picture quality. Background technique [0002] With the rapid popularization of mobile communication terminals, mobile communication terminals adopting new functions are continuously introduced, and mobile communication terminals have become comprehensive entertainment devices with more functions added. [0003] Mobile communication terminals have moved away from the concept of communication terminals used for simple phone calls, and are increasingly used as information devices using various wireless data, and even browse various contents in real time using the wireless Internet....
