It would have been obvious to a person of ordinary skill in the art to modify the teachings of the display device of Wu et al. and the driving currents of Yu et al. with the driving method of Chang et al. The motivation to modify the teachings of Wu et al. and Yu et al. with the teachings of Chang et al. is to enhance the quality of a dynamic image displayed, as taught by Chang et al. (Paragraph 14).
Response to Arguments
Regarding the first argument, in which the applicant asserts that Yu et al. fails to disclose “wherein the one of the at least one edge light-emitting element has a driving current smaller than a driving current of the second light-emitting element” of at least Claim 1. The applicant argues that Yu et al. does not discloses that the edge light-emitting element emits light of the same color as the light-emitting element not adjacent to the edge. The examiner notes that Yu et al. is not relied upon to teach this limitation. Instead, Wu et al. discloses “In addition, each light-emitting area 91 includes at least one red LED 41, at least one green LED 42, and at least one blue LED 43 (Paragraph 66. Emphasis Added).” Yu et al. discloses “As shown in FIGS. 4 and 5, the light bar 432 includes a plurality of LED lamp beads 4321, and the plurality of LED lamp beads are divided into a number N of lamp groups 45, and the N lamp groups 45 provide backlights for the N backlight subareas in a one-to-one correspondence. As shown in FIG. 5, the display device 11 further includes a circuit chip 46, and the circuit chip 46 is used to control the driving current of the LED lamp beads 4321. (Paragraph 73. Emphasis added).” Yu et al. further discloses “In this example, as shown in FIG. 7, when the display device is in the normal display mode, the driving current of the LED lamp beads 4321 in the N lamp groups 45 is shown by the second curve 72, and the equation for the second curve 72 is the second curve equation above. The driving current of the LED lamp beads 4321 in the lamp group 452 with a sequence number 8 is the same as the driving current of the LED lamp beads 4321 in the lamp group 453 with a sequence number 9 in the first direction F1, and both are a first driving current I1. In the first direction F1, the driving current of the LED lamp beads 4321 in the lamp group 451 with a sequence number 1 is the same as the driving current of the LED lamp beads 4321 in the lamp group 454 with a sequence number 16, and both are a third driving current I3, where the third driving current I3 is higher than the first driving current I1 (Paragraph 82. Emphasis Added).” Wu et al. teach the light emitting area with the color LED’s and Yu et al. teach the different LED driving voltages being used across the display. Therefore Wu et al., as modified by Yu et al. teach the above limitation with the argued color LED’s. The Office is unmoved by the applicant’s argument and the rejection is maintained.
All other arguments are found moot in light of the above rejection and/or the response to the first argument.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Uno et al. (U.S. PG Pub 2018/0210129) teaches a display device that contains LEDs to emit different colors across a back light.
Qin et al. (U.S. PG Pub 2022/0413342) teaches light structure of smaller sizes on the peripheral of a backlight.
