Claims (24)

A display apparatus for displaying hieroglyphs and / or graphic information such as alphanumeric characters and / or Asian languages including Chinese, Korean, and Thai language, includes a radio receiver circuit for receiving a radio message in which a character and / or graphic image to be displayed is encoded. And at least one display for displaying the received text and / or graphic images, and a processing circuit for receiving the radio message as an N-bit message data word in the receiving circuit. Extending the total number of displayable characters and / or graphic images to at least 2 ^N using at least one of 2 ^N (powers of 2) possible data words to alter the conversion and / or usage used to occur. Characters and / or graphics that display data words in the same way A display device, characterized in that it can be converted to a. 2. A display device according to claim 1, wherein a predetermined number X, less than 2 ^N of the possible 2 ^N combinations, is used to address the characters in the predetermined character table. The display device of claim 2, wherein X is equal to 12 and M is about 4000. 4. Claim 1 wherein, in the 2 or 3 wherein two of the 2 ^N of possible combinations of ^{the N} is less than, the number of scheduled and Y is (a) retained its image data is stored in the read / write memory, or (b) a plurality A display device used for accessing characters stored in one of the preset tables of the table, wherein the table being used is changeable by the processing circuit The display apparatus according to claim 4, wherein the image data of the alternative (a) or the table in use of the alternative (b) can be set by the command data received as part of the radio call message. A display device as claimed in claim 4 or 5, wherein Y is about 32. Claim 1 to according to any one of 6 Compounds, of one of the 2 ^N of the possible combinations, 2 ^N pieces smaller than, the number of scheduled and Z is the processing circuit is the memory of the code to translate to multiple characters to display a message or a portion thereof And a display device which is used to address the sequence of the sequence. 8. A display device according to claim 7, wherein Z is about 63. 9. A display apparatus according to claim 7 or 8, wherein the stored order can be set by command data received as part of a radio call message. 10. The processing circuit according to any one of claims 1 to 9, wherein the processing circuit is adapted to one of 2 ^N combinations received as a message word that treats one or more of the following words as bit-image data for generating a graphic image. And respond to the display device. The display device includes a wireless receiving circuit for receiving a wireless message, at least one display for displaying the received wireless message as such characters and / or graphic images, and a character and / or graphic for displaying a data word of the received message. Means for storing a value of at least one variable used by the circuitry of the apparatus for defining the characteristic of the operation between the processing circuit for converting to the image and the wireless message by the wireless receiving circuit, and at least And means for responding to at least one instruction encoded in the received message to set one such variable to the required value. 12. The device of claim 11, wherein the device is a wireless calling device, and at least one variable includes an identification code used by the circuitry of the device to determine whether a particular received wireless calling message is addressed to the device. Display device, characterized in that. Claim 1 to 10 in accordance with any one of the radio calling device complex according to claim 11 or 12. 14. Display apparatus according to any one of the preceding claims, comprising control means arranged so that the message to be displayed can be scanned in the forward or reverse direction. 15. The display apparatus according to claim 14, wherein the control means is arranged so that each message can be examined one frame when the length of the message exceeds the single frame display capacity. The display apparatus according to claim 14 or 15, wherein the control means is arranged so that the memorized message or a part thereof can be repeatedly displayed. 17. A display apparatus according to any one of claims 14 to 16, wherein the control means is arranged such that all stored messages or selected messages can be erased. 18. Display device according to any one of the preceding claims, comprising memory means capable of storing codes for at least 1000 Asian characters, in particular Chinese characters. 19. The display apparatus according to claim 18, wherein said memory means is capable of storing at least 1500 alphanumeric characters. A portable pager incorporating a wireless call circuit for receiving a radio call message and a display device according to any one of the preceding claims for displaying a received message. 21.
