Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim status
Claims 1-4, 6-11 and 13-22 are pending; claims 1, 8 and 15 are independent. Claims 5 and 12 have been cancelled.
Response to Arguments
Applicant's arguments filed 08/06/2025 have been fully considered but they are not persuasive.
In response to applicant’s argument that Nho does not disclose or teach “calculating, using a line subtractor, a data voltage transition between each line of pixel of a plurality of lines of pixels to determine a spatial interpolated voltage transition calculation”, as recited in claims 1, 8 and 15.
However, the examiner respectfully disagrees, Nho clearly taught fig. 121 and Para 0476, wherein the scaling factor may be determined in a calibration of the display panel to determine an output of each channel in response to an aggressor image/injected signal to determine channel properties to determine a common-mode error between channels. In Paras 0483-0484, the scaling factor may be determined in a calibration of the display panel to determine an output of each channel in response to an aggressor image/injected signal to determine channel properties to determine a common-mode error between channels. In Para 0307, Conversion of the correction map may be undertaken via interpolation (e.g., Gaussian, linear, cubic, or the like), extrapolation (e.g., linear, polynomial, or the like), or other conversion techniques being applied to the data of the correction map. This may allow for accounting of, for example, boundary conditions of the correction map and may yield compensation driving data that may be applied to raw display content (e.g., image data) so as to generate compensated image data 352 that is transmitted to the pixels 366.
For the same reasons rejection to claims 2-4, 6-7, 9-11, 13-14 and 16-22 still stands.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-4, 6-11 and 13-22 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nho (US 2018/0075798).
Regarding claims 1, 8 and 15, Nho teaches an electronic apparatus (fig. 108, a display 18), a computer-implemented method of operating an electronic apparatus (figs 120, 122 and 124) and one or more non-transitory computer readable media comprising computer-executable instructions (fig. 108 and Paras 0450-0451) that, when executed by one or more processors of an electronic apparatus, cause the electronic apparatus to perform operations comprising:
a memory comprising computer-executable instructions (fig. 108, a memory 1962 and Par 0451); and
a display driver integrated circuit configured to access the memory and execute the computer-executable instructions to perform operations (fig. 108, a source driver 1934 and Para 0450) comprising:
receiving an input signal frame comprising lines of pixels (fig. 108, a source driver 1934 and Para 0445, wherein the source driver 1934 may receive image data that indicates desired luminance of one or more display pixels 1940 for displaying the image frame);
calculating, using a line subtractor, a data voltage transition between each line of pixel of a plurality of lines of pixels to determine a spatial interpolated voltage transition calculation (figs 120-121 and Para 0474-0476, wherein in a sensing channel of a display, a current is sensed through the sensing channel from a target current is driven from a current source (block 2122). The current sensed on the observation channel is scaled based on a scaling factor determined during calibration (block 2126). the calibration may be repeated prior to each sensing operation to ensure accuracy of the calculations using the scaling factor. The scaled current is then subtracted from the current found in the sensed channel to determine a compensated output (block 2128);
averaging a voltage across each column within each line of pixel of the plurality of lines of pixels to determine in a group average voltage (Para 0486, wherein calibration measurements may be conducted multiple times to average the results to improve a signal-to-noise ratio of the outputs);
calculating an aggressor value for a scan phase using, as inputs, the spatial interpolated voltage transition calculation and the group average voltage (fig. 121 and Para 0476, wherein the scaling factor may be determined in a calibration of the display panel to determine an output of each channel in response to an aggressor image/injected signal to determine channel properties to determine a common-mode error between channels. In Paras 0483-0484, the scaling factor may be determined in a calibration of the display panel to determine an output of each channel in response to an aggressor image/injected signal to determine channel properties to determine a common-mode error between channels. In Para 0307, Conversion of the correction map may be undertaken via interpolation (e.g., Gaussian, linear, cubic, or the like), extrapolation (e.g., linear, polynomial, or the like), or other conversion techniques being applied to the data of the correction map. This may allow for accounting of, for example, boundary conditions of the correction map and may yield compensation driving data that may be applied to raw display content (e.g., image data) so as to generate compensated image data 352 that is transmitted to the pixels 366);
compensating per the scan phase by correcting using the aggressor value and an input sub-pixel value by aligning with a corresponding first-in first-out (FIFO) buffer to determine compensation correction voltage values (fig. 122, wherein the scaled current sense is subtracted from the sensed channel to determine a compensated output (block 2176). The compensated output is used to drive compensation operations of the display (block 2178, see also figs 124-125 and Paras 0483);
summing the compensation correction voltage values with the input signal frame to determine a compensated output image frame (fig. 123 and Para 0481, wherein a sensed observation current 2202 is scaled at scaling circuitry 2204 and subtracted from a sensed current 2206 at summing circuitry 2208 to generate a compensated output 2210 indicative of current through the sensing channel 2186 substantially attributable to the current provided by the current source 2182); and
a display panel (fig. 108, a display panel 1932) configured to display the compensated output image frame (fig. 122 and Para 0478, wherein the compensated output is used to drive compensation operations of the display (block 2178).
