Description
Technical Field
The present invention relates to a display device, and more particularly, to a display device having a driving protection mechanism and a driving protection method thereof.
Background
With the development of display technology, many display devices with light weight, thinness and power saving features have been widely used in daily life, such as liquid crystal display devices, electronic paper display devices, etc. In general, different types of display devices typically employ different display media to produce images. Taking an electronic paper display device as an example, a display medium layer of the electronic paper display device mainly comprises an electrophoretic liquid, and charged white particles and black particles. By applying voltage to the display medium layer of the electronic paper display device, the white particles and the black particles can move to specific positions to display black, white or different gray-scale images.
In the related art, the electronic paper display device drives the electronic paper display panel by directly outputting an image signal using a display driver. However, some information that needs to be kept secret (e.g., waveform control signals of the display panel) in the image signal may be analyzed and copied for use without permission. Therefore, the conventional electronic paper display device cannot provide a security measure for the image signal.
Disclosure of Invention
The invention provides a display device and a drive protection method thereof, which can carry out encryption protection on information needing to be kept secret in an image signal.
An embodiment of the invention provides a display device. The display device includes a timing controller and a source driver. The time schedule controller is used for encrypting the verification data to generate a first encryption signal. The source driver is coupled to the timing controller. And is arranged to receive the first encrypted signal. The source driver decrypts the first encrypted signal to obtain first decrypted data, and encrypts the first decrypted data to generate a second encrypted signal. The source driver outputs a second encryption signal to the timing controller. The time schedule controller decrypts the second encrypted signal to obtain second decrypted data. When the time schedule controller judges that the second decryption data is matched with the verification data, the time schedule controller enables the source driver to carry out display driving.
Another embodiment of the present invention provides a driving protection method for a display device, which includes a timing controller and a source driver. The drive protection method comprises the following steps: encrypting the verification data through a timing controller to generate a first encrypted signal; receiving the first encrypted signal through a source driver, and decrypting the first encrypted signal to obtain first decrypted data; encrypting the first decrypted data through the source driver to generate a second encrypted signal, and outputting the second encrypted signal to the timing controller; decrypting the second encrypted signal through the timing controller to obtain second decrypted data; and enabling the source driver to perform display driving through the time sequence controller when the time sequence controller judges that the second decrypted data is matched with the verification data.
Based on the above, the display device according to the embodiments of the invention includes the timing controller and the source driver. The timing controller may perform a verification operation on the source driver to determine whether the current source driver is a valid display driver. When the current source driver is determined to be a legal display driver, the timing controller enables the source driver to perform display driving. Therefore, the display device of the embodiments of the invention can perfectly protect some information (for example, the waveform control signal of the display panel) needing to be kept secret in the image signal. In addition, the timing controller and the source driver according to embodiments of the present invention have an encryption protection function, so that it is possible to ensure that the authentication signal transmitted between the timing controller and the source driver is not read by an external device when performing the authentication operation.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, characteristics and effects of the present invention will be made with reference to the accompanying drawings and preferred embodiments.
Several examples are set forth below to illustrate the invention. The invention is not limited to the illustrated embodiments. Suitable combinations between the embodiments are also allowed. The term "coupled" as used throughout this specification, including the claims, may refer to any direct or indirect connection means. For example, a first device coupled to a second device may be interpreted as being directly connected to the second device or indirectly connected to the second device through some other device or connection. Furthermore, the term "signal" may refer to at least one current, voltage, charge, temperature, data, electromagnetic wave, or any other signal or signals.
Fig. 1 is a schematic diagram of a display device according to an embodiment of the invention. Referring to fig. 1, a display device 100 of the present embodiment includes a timing controller 110 and a source driver 120. The timing controller 110 may provide a driving control signal suitable for the display device 100 to the source driver 120. The source driver 120 is coupled to the timing controller 110. The source driver 120 may receive the driving control signal and perform display driving according to the driving control signal.
In the embodiment of fig. 1, the display device 100 may be, for example, an electronic paper display device. In order to protect the driving control signals of the display apparatus 100, the timing controller 110 may perform a verification operation on the source driver 120 to determine whether the source driver 120 is a legal display driver. When the source driver 120 is determined to be a valid display driver, the timing controller 110 enables the source driver 120.
The manner in which the timing controller 110 performs the verification operation may refer to the embodiment of fig. 2. Fig. 2 is a schematic diagram illustrating a driving protection method according to an embodiment of the invention. Referring to fig. 1 and 2, the timing controller 110 may determine whether the source driver 120 is a valid display driver by using the verification data. In addition, to improve the security of signal transmission, the timing controller 110 may encrypt the authentication data to generate a first encryption signal in step S210. The verification data may be, for example, time parameters, random number data, or a combination of time parameters and random number data stored in the timing controller 110.
In step S220, the source driver 120 may receive the first encrypted signal and decrypt the first encrypted signal to obtain the first decrypted data. To improve the security of signal transmission, the source driver 120 may encrypt the first decrypted data to generate a second encrypted signal and output the second encrypted signal to the timing controller 110 in step S230.
In the above embodiments, the timing controller 110 and the source driver 120 may respectively output the first encrypted signal and the second encrypted signal by different encryption transmission methods, so as to improve the difficulty of decryption. For example, if the timing controller 110 outputs the first encrypted signal to the source driver 120 by parallel transmission, the source driver 120 may output the second encrypted signal to the timing controller 110 by serial transmission.
On the other hand, if the timing controller 110 outputs the first encrypted signal to the source driver 120 in a serial transmission manner, the source driver 120 may output the second encrypted signal to the timing controller 110 in a parallel transmission manner. In this way, even if the first encrypted signal and the second encrypted signal are obtained by an unauthorized device during transmission, the unauthorized device cannot know the content of the verification data.
Referring to fig. 1 and fig. 2 again, the timing controller 110 may decrypt the second encrypted signal in step S240 to obtain second decrypted data. The timing controller 110 may also compare the second decrypted data with the verification data to determine whether the second decrypted data matches the verification signal data. In step S250, when the timing controller 110 determines that the second decrypted data matches the verification data, the timing controller 110 may enable the source driver 120 to perform display driving. Accordingly, the present invention can protect the driving control signal of the display device 100 through the above-described verification operation manner.
Fig. 3 is a schematic view showing a display device according to another embodiment of the present invention. Referring to fig. 3, the display device 300 includes a timing controller 310, a source driver 320, and a display array 330. In the embodiment of fig. 3, the display device 300 may be, for example, an electronic paper display device, and the display device 300 has a driving protection mechanism. The timing controller 310 may perform a verification operation on the source driver 320 to determine whether the source driver 320 is a valid display driver. When the source driver 320 is determined to be a valid display driver, the timing controller 310 will enable the source driver 320 to drive the display array 330 to generate an image frame.
In the embodiment of fig. 3, the timing controller 310 includes an encoder 311, a decoder 312, a random number generator 313, a register 314, a comparator 315, a waveform control unit 316, and a time counter 317. The source driver 320 includes a decoder 321 and an encoder 322. The timing controller 310 may generate a time parameter according to the real-time information by using the time counter 317, and provide the time parameter to the random number generator 313. Timing controller 310 may use random number generator 313 to generate a set of random number data. The random number generator 313 may encode the time parameter and the random number data to generate the verification data VD, and store the verification data VD in the register 314. For example, the timing controller 310 may combine the time parameter with 24 bytes (Byte) and the random number data with 128 bytes, for example, to generate the verification data VD with 152 bytes. The timing controller 310 may, for example, improve data encryption strength by encoding according to an order of a portion of the time parameter having 12 bytes, a portion of the random number data having 64 bytes, another portion of the time parameter having another 12 bytes, and another portion of the random number data having another 64 bytes, but the present invention is not limited thereto. In one embodiment, the timing controller 310 may use other specific encoding methods to generate the verification data VD according to user design. Next, in order to improve the security of the verification process, the timing controller 310 may transmit the verification data VD generated by the random number generator 313 to the encoder 311. The encoder 311 may perform an encryption operation on the verification data VD to generate the first encryption signal FE, and output the first encryption signal FE to the source driver 320. In another embodiment, the random number generator 313 may generate a set of random number data directly as the verification data VD (may not include a time parameter).
When the source driver 320 receives the first encrypted signal FE, the source driver 320 may use the decoder 321 to decrypt the first encrypted signal FE to obtain the first decrypted data FD. At this time, if the source driver 320 directly returns the first decryption data FD to the timing controller 310, there may be a risk of data theft. Therefore, the decoder 321 can transmit the first decrypted data FD to the encoder 322, and perform an encryption operation on the first decrypted data FD through the encoder 322 to obtain the second encrypted signal SE. After the encoder 322 generates the second encryption signal SE, the source driver 320 may output the second encryption signal SE to the timing controller 310 for identity verification of the source driver 320.
In the embodiment of fig. 3, the timing controller 310 outputs the first encryption signal FE to the source driver 320 by parallel transmission, and the source driver 320 outputs the second encryption signal SE to the timing controller 310 by serial transmission. In other embodiments, the timing controller 310 may output the first encryption signal FE to the source driver 320 by serial transmission, and the source driver 320 may output the second encryption signal SE to the timing controller 310 by parallel transmission.
Referring to fig. 3 again, after the timing controller 310 receives the second encrypted signal SE, the timing controller 310 may use the decoder 312 to decrypt the second encrypted signal SE to obtain the second decrypted data SD, and output the second decrypted data SD to the comparator 315. The timing controller 310 may use the comparator 315 to read the verification data VD stored in the temporary storage 314 to compare whether the verification data VD matches the second decrypted data SD. If the comparator 315 determines that the verification data VD matches the second decryption data SD, the comparator 315 may notify the waveform control unit 316 to output the waveform control signal WAV. It is noted that the time parameter generated by the time counter 317 is not repetitive, since the time counter 317 may have a function of permanently counting without power-off. That is, the encryption strength of the first encryption signal FE generated by encrypting the verification data VD generated by combining the time parameter generated by the time counter 317 and the random number data generated by the random number generator 313 is better than that of the encryption signal generated by only the random number data of the random number generator 313.
In the present embodiment, the source driver 320 is coupled to the output end of the waveform control unit 316 to receive the waveform control signal WAV. In this way, the source driver 320 can drive the display array 330 according to the waveform control signal WAV to generate the image frame. Therefore, the present invention can protect the waveform control signal WAV output from the timing controller 310 by the verification operation manner described above.
FIG. 4 is a diagram illustrating an encryption operation and a decryption operation according to an embodiment of the present invention. Referring to fig. 3 and 4, when the timing controller 310 performs the verification operation on the source driver 320, the timing controller 310 may transmit the verification data VD generated by the random number generator 313 to the encoder 311. The encoder 311 may perform an encryption operation on the verification data VD to generate the first encryption signal FE. The encoder 311 may employ the encrypted array data 410 of fig. 4 as the first encrypted signal FE.
As shown in fig. 4, the encrypted array data 410 may include a plurality of bytes. For example: the position of number 1 represents byte 410 \u1, the position of number 20 represents byte 410 \u20, and so on. Thus, the encrypted array data 410 of FIG. 4 has 20 bytes. However, in other embodiments, the encrypted array data 410 may include a greater number of bytes. Referring again to fig. 4, the encrypted array data 410 includes one byte corresponding to the trigger data TD, at least one byte corresponding to the verification data 420 (i.e., the verification data VD of fig. 3), and at least one byte of the invalid data. For example, if the verification data 420 has 152 bytes as in the above embodiments, the encrypted array data 410 may be, for example, 400 bytes of array data having 20 rows and 20 columns.
In this embodiment, the encoder 311 of the timing controller 310 may preset the byte 410_1 as the trigger data TD. The trigger data TD is used to decide whether to perform a decryption operation. The encoder 311 may also convert 3 sub data D1, D2, D3 in the verification data 420 into corresponding 3 bytes 410 \u7, 410 \u14, 410 \u17. Accordingly, the encoder 311 may blend the byte 410 _1with the bytes 410_7, 410_14, 410 _17in a particular permutation order (referred to herein as a first permutation order) in the invalid bytes (i.e., the positions numbered 2-6, 8-13, 15-16, 18-20 in FIG. 4) to form the encrypted array data 410.
Referring to fig. 3 and 4, during the verification operation, the encoder 311 of the timing controller 310 may transmit the first encryption signal FE including the encrypted array data 410 to the decoder 321 of the source driver 320. The decoder 321 first detects the encrypted array data 410 to determine whether the encrypted array data 410 has the byte 410 \u1 corresponding to the trigger data TD. The decoder 321 will perform the decryption operation if the decoder 321 detects the byte 410_1 corresponding to the trigger data TD in the encrypted array data 410.
When the decoder 321 performs the decryption operation, the decoder 321 may designate at least one byte in the encrypted array data 410 to obtain the first decrypted data 430 (i.e., the first decrypted data FD of fig. 3). For example: the decoder 321 may specify the byte 410 \u7 in the encrypted array data 410 to retrieve the sub-data D1' in the first decrypted data 430. The decoder 321 may also specify the byte 410 _14in the encrypted array data 410 to retrieve the sub-data D2' in the first decrypted data 430. The decoder 321 may also specify the byte 410 \u17 in the encrypted array data 410 to retrieve the sub data D3' in the first decrypted data 430. In addition, if the decoder 321 does not detect the byte 410 \u1 corresponding to the trigger data TD in the encrypted array data 410, the decoder 321 does not perform the decryption operation.
The source driver 320 in fig. 3 performs the encryption operation by using the encoder 322 and the timing controller 310 performs the decryption operation by using the decoder 312 in a manner similar to that of the embodiment in fig. 4, and thus the description thereof is omitted.
Fig. 5 is a schematic diagram illustrating a driving protection method according to an embodiment of the invention. The driving protection method of the present embodiment can be at least applied to the display device 300 of the embodiment of fig. 3. Referring to fig. 3 and 5, in step S510, the time counter 317 of the timing controller 310 may generate a time parameter. In step S520, the random number generator 313 of the timing controller 310 may generate random number data, and encode the time parameter and the random number data to generate the verification data VD. The timing controller 310 may store the verification data VD in the temporary memory 314. In step S530, the encoder 311 of the timing controller 310 may generate the first encryption signal FE including the verification data VD and output the first encryption signal FE to the source driver 320. In step S540, the decoder 321 of the source driver 320 may decrypt the first encrypted signal FE to obtain the first decrypted data FD.
In step S550, the encoder 322 of the source driver 320 may encrypt the first decrypted data FD to obtain the second encrypted signal SE, and output the second encrypted signal SE to the timing controller 310. In step S560, the decoder 312 of the timing controller 310 may decrypt the second encrypted signal SE to obtain the second decrypted data SD, and output the second decrypted data SD to the comparator 315.
When the comparator 315 receives the second decrypted data SD, the comparator 315 of the timing controller 310 may read the verification data VD stored in the register 314 in step S570 to compare whether the verification data VD matches the second decrypted data SD. If the verification data VD matches the second decryption data SD, the timing controller 310 may enable the waveform control unit 316 to output the waveform control signal WAV in step S580. In addition, if the verification data VD does not match the second decryption data SD, the timing controller 310 may disable the waveform control unit 316 in step S590. Therefore, the present invention can protect the waveform control signal WAV by the above-described verification operation manner.
In summary, the display device according to the embodiments of the invention includes a timing controller and a source driver. The timing controller may perform a verification operation on the source driver to determine whether the current source driver is a valid display driver. When the current source driver is determined to be a legal display driver, the timing controller enables the source driver to perform display driving. Therefore, the display device of the embodiments of the invention can perfectly protect some information (for example, the waveform control signal of the display panel) needing to be kept secret in the image signal. In addition, the timing controller and the source driver according to embodiments of the present invention have an encryption protection function, so that it is possible to ensure that the authentication signal transmitted between the timing controller and the source driver is not read by an external device when performing the authentication operation.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
