Description

Technical Field

[0001] The utility model relates to the technical field of visual debugging structures, in particular to a visual debugging structure for a VCOM value. Background Art

[0002] The existing TFT liquid crystal display is an active matrix liquid crystal display driven by an AC signal. The voltage polarity needs to be switched between positive and negative when each frame is switched to avoid liquid crystal polarization. When the positive and negative voltages applied to both ends of the liquid crystal are inconsistent, the efficiency of liquid crystal light transmission is different, resulting in flicker. In order to improve the flicker problem, it is necessary to optimize the positive and negative voltages at both ends of the liquid crystal to be consistent. This process is called finding the optimal VCOM value in the industry.

[0003] At present, the existing devices for finding the best VCOM value are mostly displayed through the indicator lights on the PG dot screen fixture when in use. This method adjusts the output value according to the number of indicator light responses during measurement, so as to perform measurement. This method is inconvenient for displaying the measurement process when in use, and cannot display the VOCM algorithm more intuitively, which easily leads to fuzzy measured VOCM values, resulting in data errors and affecting experimental efficiency.

[0023] In view of the problems existing in the prior art, the utility model provides a visual debugging structure of a VCOM value, wherein a fixed card block 11 is fixedly installed on the rear side end of the mounting base 1; a card slot 13 is fixedly installed on the side end of the fixed bottom plate 12, and the mounting base 1 part is slidably mounted on the fixed bottom plate 12 through the cooperation of the fixed card block 11 and the card slot 13; a linkage slot 18 is provided on the side end of the dust cover 17, and by installing a PC computer 14 part in the mounting base 1, and cooperating with the fixed card block 11 and the card slot 13 part, the PC computer 14 part can be quickly installed and fixed.

[0024] Two rotating columns 19 are fixedly installed at the lower end of the dust cover 17; the dust cover 17 is rotatably installed by cooperating with the rotating columns 19 and the openings on the front side of the mounting base 1, and a display panel 15 is fixedly installed on the front side of the PC 14; a control board 16 is fixedly installed on the front side of the PC 14, and the rotating columns 19 installed below the dust cover 17 and the holes opened on the front side of the mounting base 1 can achieve the effect of protecting the PC 14 when not in use.

[0025] Connecting plugs 23 are fixedly installed on both sides of the transmission line 24, and a connecting groove 21 is opened at the upper end of the PG dot screen fixture 2; the transmission line 24 is connected and installed with the PC computer 14 and the PG dot screen fixture 2 through two connecting plugs 23, and the PG dot screen fixture 2, the connecting plug 23, and the transmission line 24 are connected together, so that the device can be quickly disassembled for easy storage and carrying.

[0026] Working principle:

[0027] The first step is that when the user is in use, the device is placed on a horizontal surface, the user picks up the mounting base 1, installs the fixed card block 11 at the rear of the mounting base 1, then installs the PC 14 inside the fixed card block 11, then installs the display panel 15 at the side of the PC 14, and then installs the control board 16 on the same side of the PC 14 where the display panel 15 is installed, then the user picks up the dust cover 17, installs two rotating columns 19 under the dust cover 17, then picks up the fixed bottom plate 12, installs the card slot 13 at the side of the fixed bottom plate 12, then the user picks up the transmission line 24, and installs the connecting plugs 23 on both sides of the transmission line 24 , then pick up the PG dot screen fixture 2, install the indicator 22 on the side end of the PG dot screen fixture 2, and then the user fixes the fixed base plate 12 part along the side end opening at the specified position, and then pick up the mounting base 1 part and match it with the fixing block 11 and the card slot 13 to assemble the mounting base 1 part with the fixed base plate 12 part, and then pick up the dust cover 17, and install it along the rotating column 19 and the front opening of the mounting base 1, and then the user picks up the transmission line 24 part and installs it above the PC computer 14 along the connecting plug 23, and then installs the connecting plug 23 on the other side of the transmission line 24 into the connecting slot 21 opened in the PG dot screen fixture 2.

[0028] In the second step, when the user needs to use the device, the user picks up a new transmission line 24, inserts it into the position below the PG dot screen fixture 2, and then connects the other side to the display device. Then the user pulls the linkage slot 18, thereby driving the dust cover 17 to rotate along the rotating column 19, and rotates it downward from the front side of the mounting base 1. Then the user divides the display panel 15 interface into four areas through the operation control panel 16, namely the parameter setting area, the test data display area, the chart generation area, and the status area. Then the operation control panel 16 starts the PC computer 14 to start the test. In the parameter setting area, the VCOM value range to be found needs to be set, including the maximum value (VCOMmax) and the minimum value (VCOMmin), and the F li cker picture for finding the best VCOM is set; the test data display area is used to display the currently tested VCOM value and the corresponding F li cker value measured (negative value, unit is dB, the smaller this value is, the better the display screen flickering state is); the chart generation area generates the corresponding chart curve according to the test data, which is convenient for intuitively confirming the F li cker value and VCOM value; the status area is used to display the communication status of the PC 14 connected to the PG dot screen fixture 2 through the transmission line 24, and can also be displayed through the indicator 22 installed on the front side of the PG dot screen fixture 2. The PC 14 obtains VCOMmax, VCOMmin and F li cker images according to the settings in the parameter setting area, and then the PC 14 sends a communication instruction containing the VCOM setting value and F li cker image information to the PG dot screen fixture 2 through the transmission line 24. After receiving the instruction, the PG dot screen fixture 2 sends the measured corresponding VCOM value back to the PC 14, and then displays it on the display panel 15.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
