The adjustment of sequence controller 16 trigger pulse corresponding with the sub- viewing area of the more late reception scanning signal is believed Phase of the phase of number TP earlier than start pulse signal TP corresponding with the more early sub- viewing area for receiving the scanning signal.Second The time that the time viewing area A1 than first that sub- viewing area A2 receives the scanning signal receives the scanning signal is late, and the The time that the time viewing area A2 than second that three sub- viewing area A3 receive the scanning signal receives the scanning signal is late.Cause This, as shown in Fig. 2, the phase of the adjustment of the sequence controller 16 start pulse signal TP corresponding with the described second sub- viewing area A2 Phase of the position earlier than start pulse signal TP corresponding with the described first sub- viewing area A1, and adjust and the sub- viewing area of the third Phase of the phase of the corresponding start pulse signal TP of A3 earlier than start pulse signal TP corresponding with the described second sub- viewing area A2 Position, can increase the charging time of the pixel 18 of the described second sub- viewing area A2 and the picture of the sub- viewing area A3 of the third whereby The charging time of element 18.

It will be described below how calculating the phase of the corresponding start pulse signal TP in different sub- viewing areas.Assuming that described first The goal-setting of the charging time T_chargetop of gate lines G 1 is 1 microsecond (microsecond, μ s), is located at the display The goal-setting of the charging time T_chargemid of gate lines G 1080 among area 10 is 1.3 μ s, the last item grid The goal-setting of the charging time T_chargebtm of line G2160 is 1.5 μ s.The clock frequency Fclk of the display device is 74.26 megahertzs (MegaHertz, MHz), clock cycle Tclk (Tclk=1/Fclk) be 13.466 nanoseconds (nanosecond, ns)。

Assuming that the initial value of the phase of start pulse signal TP corresponding with first gate lines G 1 is 200, represent The source drive unit 12 is started counting receiving the start pulse signal TP that the sequence controller 16 is transmitted, and is being counted The pixel 18 that data-signal write-in is electrical connected with first article of gate lines G 1 when the 200th pulse of number.

Grid line between first gate lines G 1 and the gate lines G 1080 (being located among the viewing area 10) The phase calculation of the start pulse signal TP_up (n) of (upper half of the i.e. described viewing area 10) is as follows.It is found out first every several Grid line adjusts the phase of a pulse of start pulse signal TP:

TP_up_c=grid line line number/((T_chargemid-T_chargetop)/Tclk)

=1080/ ((1.3 μ s-1 μ s)/13.466ns)=48.47 ≈ 48

That is, every 48 grid lines adjust the phase of a pulse.Therefore, the trigger pulse letter of line n grid line Number phase TP_up (n) can be calculated by following formula:

TP_up (n)=initial value-(n-1)/TP_up_c=200- (n-1)/48

The charging time T_up_charge (n) of the pixel 18 of line n grid line can be calculated by following formula:

T_up_charge (n)=T_chargetop+ (TP_up (n)-initial value) × Tclk

=1.0+ (TP_up (n) -200) × Tclk

Similarly, the grid between the gate lines G 1081 (being located among the viewing area 10) and the gate lines G 2160 The phase calculation of the start pulse signal TP_down (n) of polar curve (lower half of the i.e. described viewing area 10) is as follows.It finds out first every Every the phase of a pulse of several grid line adjustment start pulse signal TP:

TP_down_c=grid line line number/((T_chargebtm-T_chargemid)/Tclk)

=1080/ ((1.5 μ s-1.3 μ s)/13.466ns)=72.7 ≈ 73

That is, every 73 grid lines adjust the phase of a pulse.Therefore, the trigger pulse letter of line n grid line Number phase TP_down (n) can be calculated by following formula:

TP_down (n)=TP_up (1080)-(n-1080)/TP_down_c

=177- (n-1080)/73

The charging time T_down_charge (n) of the pixel 18 of line n grid line can be calculated by following formula:

T_down_charge (n)=T_chargetop+ (TP_down (n)-initial value) × Tclk

=1.0+ (TP_down (n) -200) × Tclk
