1. A method of displaying image data, the method comprising:
- reading first layer data;
reading partial data of second layer data;
blending the first layer data and the partial data of the second layer data to generate blended data; and
displaying the blended data,wherein the second layer data comprises valid data and invalid data,wherein reading the partial data of the second layer data comprises reading the valid data of the second layer data not the invalid data of the second layer data, andwherein the second layer data is divided into a plurality of data blocks, each block being validated or invalidated independently.

Abstract
Provided are an image display method and an image display device. The method includes: reading first layer data; reading partial data of second layer data; and blending the read first layer data and the read partial data of the second layer data and displaying the blended data. The image display device includes: a processing unit generating first and second layer data and storing the generated first and second layer data in a storage unit; and a display unit reading the first layer data and partial data of the second layer data from the storage unit, blending the read first layer data and the read partial data of the second layer data, and displaying the blended data.

10. A method of displaying an image, the method comprising:
-
reading first layer data and second layer data from an image display device data storage unit; detecting invalid data in the second layer data; storing, in a display buffer, information corresponding to the invalid data in the second layer data; adjusting the second layer data responsive to the invalid data of the second layer data not the first layer data; generating a display frame by blending the first layer data and adjusted second layer data; and displaying the display frame generated by blending the first layer data and the adjusted second layer data. - View Dependent Claims (11)

12. An image display device comprising:
-
a processing unit that is configured to generate first layer data and second layer data and to store the generated first layer data and the generated second layer data in a storage unit; and a display unit that is configured to read the first layer data and partial data of the second layer data from the storage unit, to blend the first layer data and the partial data of the second layer data to generate blended data, and to display the blended data, wherein the display unit comprises a display buffer that is configured to store information about valid data and invalid data in the second layer data and to read the valid data in the second layer data from the storage unit based on the information stored in the display buffer without reading the invalid data in the second layer data, wherein the second layer data is divided into a plurality of data blocks;
the plurality of data blocks correspond to a plurality of bits of the display buffer, respectively; and
according to whether a specific data block among the plurality of data blocks includes a valid pixel value or not, setting a corresponding bit of the plurality of bits of the display buffer as a first logic value or a second logic value, andwherein, when the second layer data are updated, the processing unit is configured to activate a reset signal and the display unit is configured to reset the plurality of bits of the display buffer as the first logic value in response to the activated reset signal. - View Dependent Claims (13)

14. An image display device comprising:
-
a processing unit that is configured to generate first layer data and second layer data and to store the generated first layer data and the generated second layer data in a storage unit; and a display unit that is configured to read the first layer data and partial data of the second layer data from the storage unit, to blend the first layer data and the partial data of the second layer data to generate blended data, and to display the blended data, wherein the processing unit is further configured to store third layer data in the storage unit, wherein the display unit is further configured to read the first layer data, the partial data of the second layer data, and partial data of the third layer data from the storage unit, to blend the first layer data, the partial data of the second layer data, and the partial data of the third layer data, and to display the blended data, wherein the display unit comprises; a first display buffer that is configured to store information about valid data and invalid data in the second layer data; and a second display buffer that is configured to store information about valid data and invalid data in the third layer data, wherein the display unit is configured to read valid data in the second layer data from the storage unit based on the information stored in the first display buffer and to read valid data in the third layer data from the storage unit based on the information stored in the second display buffer. - View Dependent Claims (15)
