Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1, 8, 9, 11, 12 and 14-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cho et al (U.S. Patent Pub.

No. 2017/0061875; hereinafter referenced as Cho’875). Regarding claim 1, Cho discloses a display device (1), (fig. 1, [0058]), comprising: a first pixel (PX2) including a first organic light emitting diode (OLED); a second pixel (PX1) including a second organic light emitting diode (OLED); a third pixel (PX3) including a third organic light emitting diode (OLED), (fig. 27, [0145]); an initialization voltage generator (display driver 32 and transistors TB) configured to generate a first initialization voltage (Vaint1) and a second initialization voltage (Vaint2), supply the first initialization voltage (Vaint1) to the first organic light emitting diode (i.e. OLED of pixel PX2), supply the second initialization voltage (Vaint2) to the third organic light emitting diode (i.e. OLED of pixel PX3) and supply one of the second initialization voltage (Vaint2) to the second organic light emitting diode (i.e. OLED of pixel PX1), in response to a select signal (i.e. scan signals GB controls initialization transistor TB for transmitting initialization voltages Vaint1 or Vaint2 to the pixels PX1-PX3), (figs. 2 and 27, [0073, 0084 and 0145]), wherein the initialization voltage generator includes: a first transistor (transistor TB of PX2) connected to a first anode of the first organic light emitting diode (OLED of PX2); and a second transistor (transistor TB of PX1) connected between the second anode (i.e. anode of OLED of PX1) and a third anode of the third organic light emitting diode (i.e. anode of OLED of PX3) through transistor TB of PX3, (fig. 27, [0145]). However, Cho does not mention a first transistor connected between a first anode of the first organic light emitting diode and a second anode of the second organic light emitting diode.

Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Cho, by specifically providing the first transistor connected between the first and second EL, as taught by Lee, for the purpose of preventing image quality deterioration due to a ripple of a pixel ground voltage supply voltage, [0008]. However, Cho in view of Lee does not mention wherein the first transistor and the second transistor are complementary transistors that cooperate to selectively connect the second anode to the first initialization voltage or the second initialization voltage. In a similar field of endeavor, Cho’875 teaches wherein the initialization voltage generator (160) includes: wherein the first transistor (MS1) and the second transistor (MS2) are complementary transistors that cooperate to selectively connect the second anode (i.e. anode of the OLED of pixel 140) to the first initialization voltage (Vint1) or the second initialization voltage (Vint2) through transistor M7, (figs. 2-3, [0072, 0079 and 0081]). Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Cho in view of Lee, by specifically providing the first and second transistor are complementary transistors that cooperate to selectively connect the anode of the OLED to the first or second initialization voltage, as taught by Cho’875 for the purpose of improving display quality, [0011].

However, Cho in view of Lee does not mention wherein the first transistor and the second transistor are complementary transistors that cooperate to selectively connect the second anode to the first initialization voltage or the second initialization voltage. In a similar field of endeavor, Cho’875 teaches wherein the initialization voltage generator (160) includes: wherein the first transistor (MS1) and the second transistor (MS2) are complementary transistors that cooperate to selectively connect the second anode (i.e. anode of the OLED of pixel 140) to the first initialization voltage (Vint1) or the second initialization voltage (Vint2) through transistor M7, (figs. 2-3, [0072, 0079 and 0081]).

Regarding claim 12, Cho discloses wherein the first transistor is a P- type transistor (i.e. transistor TB of PX2 is p-type), (fig. 28, [0158]).

In a similar field of endeavor, Lee teaches the second transistor (i.e. switch element M02 of left pixel) is an N-type transistor (n-channel oxide TFTs), (fig. 8, [0070]). Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Cho, by specifically providing the first transistor connected between the first and second EL, as taught by Lee, for the purpose of preventing image quality deterioration due to a ripple of a pixel ground voltage supply voltage, [0008].

However, Cho does not mention a first transistor connected between a first anode of the first organic light emitting diode and a second anode of the second organic light emitting diode. In a similar field of endeavor, Lee teaches the switching circuit comprises: a first transistor (i.e. switch element M02 of middle pixel) connected between a first anode of the first organic light emitting diode (i.e. anode of middle EL) and a second anode of the second organic light emitting diode (i.e. anode of left EL) through transistor M02 of left pixel; and a second transistor (i.e. switch element M02 of left pixel) connected between the second anode (i.e. anode of left EL) and a third anode of the third organic light emitting diode (i.e. anode of right EL) through transistor M02 of the right pixel, (fig. 8, [0075, 0078 and 0106]).

Regarding claim 5, Cho discloses wherein the first transistor is a P- type transistor (i.e. transistor TB of PX2 is p-type), (fig. 27, [0158]).

In a similar field of endeavor, Lee teaches the second transistor (i.e. switch element M02 of left pixel) is an N-type transistor (n-channel oxide TFTs), (fig. 8, [0070]). Therefore, it would have been obvious to one of ordinary skills in the art at the effective filing date of the claimed invention to modify Cho, by specifically providing the first transistor connected between the first and second EL, as taught by Lee, for the purpose of preventing image quality deterioration due to a ripple of a pixel ground voltage supply voltage, [0008].

However, Cho in view of Lee in view of Cho’875 in view of Kim and in view of Kim’117 does not mention when the select signal turns on the second transistor, the second initialization voltage is supplied to the first anode of the first organic light emitting diode.

Regarding claim 16, Cho in view of Lee and in view of Cho’875 discloses everything as specified above in claim 15. However, Cho in view of Lee and in view of Cho’875 does not mention the first transistor is activated in response to a first level of the select signal and the second transistor is activated in response to a second level of the select signal. In a similar field of endeavor, Liu teaches wherein the first transistor (Ms1) is activated in response to a first level of the select signal (EM) and a second transistor (Ms2) that is activated in response to a second level of the select signal (i.e. phase inverted signal XEM of the control signal EM), (fig. 8b, [0114-0118]).

Response to Arguments Applicant’s arguments with respect to claim(s) 1, 8 and 15 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. In view of amendment, the reference of Cho’875 has been added for new grounds of rejection.
