Problems solved by technology

[0010] However, in such a conventional display device, the use of an EEPROM separate from the microcontroller unit to store color data causes a decrease in update operation speed while increasing cost
[0011] In addition, when the built-in RAM (or separate RAM) of the micro control unit is used in the display device, the RAM is divided into the general-purpose RAM area 110a for general data processing and the color data area 110b, which may cause other required processing. not enough space
[0012] Therefore, since the flash ROMs 100a and 100b in the MCU are not used to store color data, the execution speed of color adjustment is reduced

Abstract

A display apparatus includes a display unit to display an image, an image processing unit to apply an image signal to the display unit, a nonvolatile memory having a data area to adjust a display state of the image displayed on the display unit, a correction data area to store predetermined correction data, and a program code area to store program codes, and a micro control unit to control the image based on the program codes and to change the correction data such that a data checksum value of the data area and the correction data area is conserved as a predetermined reference data checksum value when data stored in the data area are changed.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2005-0076714 filed with the Korean Intellectual Property Office on Aug. 22, 2005, the contents of which are incorporated herein by reference. technical field [0002] The general inventive concept of the present invention relates to a display device and a control method thereof, and more particularly, to a display device in which color data stored in a color data area of ​​a nonvolatile memory provided in a micro control unit is When changing, the checksum value of all data in the non-volatile memory can also be saved, and the invention also relates to a control method of the display device. Background technique [0003] Generally, a display device processes an image signal with a predefined color mode (such as gray mode, RGB mode or CYMK mode) transmitted from a signal source (information processing device, such as a computer) so as to provide visual images to users. The display device adjusts the g...
