Technical Field of the Invention The present invention relates to a display device and a brightness adjustment method, and in particular, to a display device capable of improving the brightness unevenness caused by black insertion technology and Brightness adjustment method. [Prior Art] 0 Liquid Crystal Display (LCD) gradually replaced the conventional cathode ray tube display (CRT) and became the mainstream display. The display principle of the liquid crystal display utilizes a voltage to control the deflection angle of the liquid crystal molecules, so that the light emitted by the backlight passes through the liquid crystal molecules to generate different gray levels through different deflection angles. In addition to the different illumination principles, liquid crystal displays and cathode ray tube displays are also driven differently. The conventional cathode ray tube is an impulse type driving method, and the liquid crystal display is a holding type (h〇w o type) driving method. Due to different driving methods, liquid crystal displays are more prone to dynamic blur than cathode ray tube displays when playing back motion pictures. In the prior art, the Simulated Puh Driving method is commonly used to solve the dynamic image sticking problem of liquid crystal displays. Please refer to the figure - '图-' for the purpose of the analog pulse driving method of the prior art. As shown in Figure -, the horizontal axis is time t and the vertical axis is the voltage V that drives the busy source input. When the analog pulse driving method is not used, the driving signal 1 maintains a voltage for the first time, that is, the driving of the 201044355 source is at f; the input voltage is within a time T1. On the other hand, when the analog pulse driving method is used, the source is input in the second time T2, and the remaining time Τ3 is input into the black data. Therefore, the actual face data input time is only one Β, and Τ 2° due to this method. Compared with the driving method of the original liquid (four) display device, it is closer to the pulse driving method used in the cathode ray tube, and therefore the method can effectively improve the (4) image product f to avoid the condition of the moving image. However, the 'nuclear pulse driving method will cause the brightness of the liquid crystal panel to be uneven. Referring to Fig. 2', Fig. 2 shows the prior art liquid crystal display panel. As shown in FIG. 2, the liquid crystal display panel 2 includes scan lines G1 to G480 arranged in order on the panel. Please note that for the sake of simplicity, the figure is drawn only by tf. The traces represent all the scan lines, and the distance between each scan line and the adjacent scan lines is substantially the same. The surface data can be self-scanned, G1 scans to scan line G48q sequentially, and # data signal scans to scan line G360. The black information number can be scanned from the scan line (1). In the prior art, the liquid crystal display panel 2 is also provided with a blanking area, which is also an area represented by G481 to G525 of Fig. 2 . After scanning the data signal to the scanning line G480, it can enter the blanking area, and scan from the scanning line G481 to the scanning line G525 and then back to the scanning line G1 for re-scanning. Since the occlusion area is not a physical display area, when the scan to the occlusion area, the drive 1C does not perform polarity and data conversion (ie, stop inputting the data signal), so the drive 1C can have a longer charging time. And a larger thrust to wheel in the black information number, which will cause the human eye to feel that this area (G122~G163) is blacker than other areas. In summary, although the analog pulse method can improve the residual image of the liquid crystal display 5 201044355 phenomenon, however, this method also causes the disadvantage of uneven brightness of the overall surface. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a display device which can improve the problem of uneven brightness of the kneading surface caused by the analog pulse driving method.

The clock generator can generate N trigger signals and one blanking signal in a written C) cycle, where both M and N are natural numbers. In this embodiment, the control module can receive the [S] trigger signal, and when it receives one of the N trigger signals, the control module can selectively input the first black input signal to N One of the liquid crystal cells. In addition, the control module can also receive M blanking signals, and when receiving one of the black insertion signals, the control module can input the first black insertion signal to one of the liquid crystal display units. Please note that the first black signal is different from the second black signal. Another aspect of the present invention is to provide a brightness adjustment method which can be used to solve the problem of uneven brightness of a liquid crystal display caused by an analog pulse driving method.

In this embodiment, the brightness adjustment method may include the following steps: The control module receives one of the N trigger signals, and selectively inputs the first black insertion signal to the N liquid crystal units according to the trigger signal. And the control module receives one of the two blanking signals, and inputs the second black signal to one of the liquid crystal displays according to the blanking signal. Among them, the first black insertion signal is different from the second black insertion signal. The advantages and spirit of the present invention will be further understood from the following detailed description of the invention. [Embodiment] Referring to FIG. 3A and FIG. 3 together, FIG. 3 is a functional block diagram of a display device 3 according to an embodiment of the present invention, and FIG. 3B is a display of FIG. A schematic view of the appearance of the device 3. As shown in FIG. 3A, the display device 3 includes n liquid crystal cells 3, a clock generator 32, and a control module 34. The control module 34 can be electrically connected to the clock generator 32 and each liquid crystal cell%. In this embodiment, the clock generator 32 sequentially generates N trigger signals and a blanking signal in a frame period, wherein M and N are consecutive numbers. Please note that in practice, M and N may be determined according to the user or the heart, and are not limited to the specific embodiments listed in the present specification. For example, t, Ν can be set to ·, PCT can be set to shirt, 7 201044355 = The designed display has a weight scan line, and the 481th to 525th scan lines are the occlusion area, please no area is not a display device The entity display area of 3, but the virtual area set for the needs of the symbol. As shown in FIG. 3B, the display 3 〇 is the display area and the scan lines G481, GG525, 2 can be triggered according to the trigger generated by the clock generator 32; the 枓 枓 枓 描 描 , , , , , , Ο ❹. And at the same time, when the control module 34 == / signal, the input data signal is stopped. N liquid crystals can be compared with each other, and the scanning lines of the display area, in other words, the display device in practice = scan the G1, ~G· according to the f scan, the program is to sequentially control each liquid crystal cell 30 The deflection of the liquid crystal molecules (not shown) contained therein.啧,,,,, for the sake of simplicity of the drawing, Figure 3B only shows a number of scans ^ to represent all scan lines. In order to improve the image sticking phenomenon of the display device 3, it can be set to start from the scanning line of the first (G1,) when the display device 3 reads the scanning line to the 360th scanning line (ie, G360) by the material signal. The black signal is scanned. The above-mentioned black insertion signal can be scanned according to the timing or the designer's request. In the case of ^, the designer can design to scan the data signal to the second part. In the present embodiment, the face period refers to the time taken by the clock generator 32 to generate N trigger signals and M mask signals, and one face period may present a frame frame. Please refer to FIG. 3B. FIG. 3C is a detailed schematic diagram of the display device 3 of FIG. 3A. As shown in FIG. c 8 201044355, the control module 34 can further include a source driving circuit, a gate driving circuit 342, and a timing controller 344. The trigger signal and the blanking signal sequentially generated by the clock generator % can be received by the control module 34. When the control module 34 receives the trigger signal, the timing controller 344 can control the gate driving circuit 342 to select the liquid crystal according to the trigger signal. One of the cells 3 is wheeled with a gate voltage. According to an embodiment, if the clock generator 32 generates the first trigger signal in a buffer cycle, the timing controller 344 controls the gate driving circuit 342 to the first liquid crystal cell according to the first 触发 trigger signal. 3〇 (in the present embodiment, the first liquid crystal cell 3〇 corresponds to the scan line G1), the gate voltage is input. In other words, when the first liquid crystal cell 30 receives the gate voltage, the transistor of the liquid crystal cell is in an on state. In addition, the timing controller 344 can also control the source driving circuit 340 to input the first source signal to the liquid crystal cell according to the first trigger signal. The gate voltage and the first source voltage may constitute a first black insertion signal in this embodiment. In addition, in the specific embodiment, when the timing controller 344 receives the blanking signal generated by the temple generator 32, the timing controller 344 can control the gate driving circuit 342 to input one of the liquid crystal cells 3 Gate voltage: At the same time, the source driving circuit 340 can control the input of the second source voltage to the liquid crystal cell 3, and in practice, the gate voltage and the second source voltage can constitute a second black insertion signal. . As shown in the color, when the pulse generator generates the trigger signal, the timing controller can control the source driving circuit and the gate driving circuit to generate and input one of the first black insertion signals to the liquid crystal unit. In addition, the timing generator produces 9 201044355 Ο 遮 遮 / 又 又 ' ' ' 时序 时序 时序 时序 时序 时序 时序 时序 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 时序The first insertion of HeiXin County is different from the second black signal. For example, when the display device scans the scan line to the scan line in the display area by the data signal, the control module inputs the first black signal from the first scan line and scans down the first black line. Moreover, when #时脉产 produces a masking ^, (4) modulo m black 峨 replaces the first - insert black signal continues to Ί 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生During the simple scan, the (4) module replaces the second black insertion signal with the first black insertion signal to continue scanning. Since the shop 1C (4) Chengsheng n does not perform polarity or data conversion when it is discriminating, in the section where the clock generator generates the blanking signal, the charging _ used to provide the black signal is generated and the thrust is generated by the clock. The device generates a trigger when calling for the township. In this frequency, if you only insert a black signal with a black plug, for example, the first black signal, the first field will have a darker color. However, this section replaces the first-inset black nickname with the second black-out signal, which can solve the problem of uneven brightness of the device. According to the second embodiment of the second black signal, the pressure system is smaller than the first source included in the first black signal, and the clock is produced in the clock. Raise the excessive charging time and the thrust to insert the black signal to cause the display decoration = the color of the segment lion (that is, the 'low brightness'). Please note; t the second source voltage in the practice of blood - the ratio of the heart to the voltage can be based on the user's ten, and in general, the design is based on the general eye 201044355 ',,, negative The brightness of the device may be uneven.

Therefore, the section of the clock generator that produces the obscuration signal has a scent. Although the 1C provides more charging and the thrust to the second blackout, the first black signal duration is shorter than the first black signal. The two positive body k into the black effect is similar. Similarly, in practice, the second output, the interval between the first and the first time can be determined according to the needs of the rider or the designer. Generally, §, the design is substantially indistinguishable from the brightness of the overall display device. The phenomenon can be. In practice, the brightness of the first black input signal and the second black input signal are affected by the source voltage and the input time. Therefore, according to another embodiment, the control module can control the first black insertion signal. The product value obtained by multiplying the source voltage by the first output time corresponding to the gate voltage is substantially equal to the second source voltage of the second black insertion signal multiplied by the second output time corresponding to the gate voltage thereof. The product value obtained. The product values of the first black insertion signal and the source voltage of the second black insertion signal and the gate voltage input time are substantially equal, such that the brightness exhibited by the two on the display device is substantially the same as that of the 201044355. = Fig. 4 is a flow chart showing the steps of the method according to an embodiment of the present invention. The brightness adjustment method of the present embodiment can be applied to the apparatus of the above (4) embodiment, and as described in the above specific embodiment, the display device can include N liquid crystal cells, a clock generator, and a control module. Please note that the display device and its internal components have been disclosed in the above specific embodiments, and thus will not be described again. As shown in FIG. 4, the brightness adjustment method of this embodiment includes the following steps. In step S4G', the control group is multiplexed to generate the N-side signal of the rider, and the first black-out signal is selectively inserted into one of the N liquid crystal cells according to the received signal. In addition, in step S42, the control module receives one of the occlusion signals generated by the clock generator, and inputs the first black insertion signal to one of the liquid crystal units according to the received occlusion signal. One. Please note that the first black insertion signal is different from the second black insertion signal. ❹ Since the clock generator sequentially generates one trigger signal and μ blanking signals, the sequence of steps in the specific embodiment is followed by step S42 following step S40. In addition, after generating the M occlusion signals, the clock generator can sequentially generate N trigger signals and M occlusion signals, that is, generate N trigger signals and M occlusion numbers in the next frame period. The display device is caused to display the next face. As described above, according to another embodiment, the step S4 of the brightness adjusting method of the present invention and the step S42 are alternately performed to continuously adjust the brightness of the face. In the method for adjusting the intensity of the specific embodiment, the control module can control the product of the 12th 201044355 black input signal and the second black input signal source voltage and the gate voltage output 2, or control the multiplication of the two. They are roughly equal to improve the problem of unevenness in the picture. Regarding the control when the black signal is generated by the clock generator to generate different signals (trigger signals or blanking signals), the foregoing specific embodiments have been fully disclosed, and thus will not be further described herein. Referring to FIG. 5, FIG. 5 is a flow chart showing the steps of a method for adjusting the degree of shell according to another embodiment of the present invention. As shown in Fig. 5, the method for adjusting the shell degree of the specific example includes the following steps. In step s5, the control module receives one of the N trigger signals, inputs a data signal to one of the N liquid crystal cells according to the received trigger signal, and selectively inserts the first black signal. To the other of the N liquid crystal cells. In step S52, the control module receives one of the M occlusion signals, stops inputting the data signal according to the received occlusion signal, and inputs the second black insertion signal to one of the N liquid crystal cells. In this embodiment, the control module can sequentially input the data signal to the liquid crystal unit according to the trigger signal generated by the clock generator to display the surface, and when the one trigger signal is generated, the control module pairs the liquid crystal unit. Enter the first black signal. In addition, when the clock generator generates the blanking signal, the control module has input to the last liquid crystal unit and stops inputting the data signal, and the control module replaces the first black input signal with the second black input signal to the liquid crystal unit. By the difference between the second black insertion signal and the first black insertion signal, the display device can adjust the black degree of the black signal inserted in the picture to improve the uneven brightness of the kneading surface. Compared with the prior art, the display device and the brightness 13 201044355 provided by the present invention are based on the fact that the _IC does not perform the polarity and the rotation (four) to adjust the black degree of the black signal to improve the analog pulse driving method. Degree: The problem is that the black signal can be adjusted by adjusting the source voltage, the opening voltage input time or the product value of the two, so that the ic is caused by more thrust and charging_inputting the black signal. The area is adjusted to the degree of blackness to improve the unevenness of the brightness of the picture. r The details of the specific embodiment 'are hoping to be more clear and ambiguous' and not limited by the preferred instructions disclosed above. Conversely, the purpose is within the scope of the patent scope.
