In addition, the rotary pattern inspection apparatus for LCD further comprises an LCD display 240, and a switch 250.

The presentation control unit 150 is also applicable to the samples having the state of the LCD folder assembly, LCD SMD assembly, and FPC assembly.

The rotary data interface 100 transfers data at high speed by driving a presentation driver program including a RAM 210 for downloading a graphic pattern presentation driver from the parallel port 12 and storing the graphic pattern. Provide data boundaries.

In addition, the presentation control unit 150 of the mobile phone LCD commands the graphic pattern received from the rotary data interface 100 to drive the presentation driver as data and control signals, and the commanded graphic pattern signal is a normal signal. Feedback to the rotary data interface 100 is returned.

In addition, between the CPU 200 and the rotary data interface 100, under the control of the presentation control unit 150 of the mobile phone, amplified signal data of a continuous variable through an operational amplifier (not shown) is converted into an amplified graphic pattern and outputted.

Next, with reference to Figure 2 will be described the operation principle in consideration of the role that the mobile phone functions as a substitute for this equipment.

2 is a flowchart partially showing an operation part of the method using the rotary device for inspecting the LCD pattern according to the present invention.

In the rotary method using the LCD pattern inspection rotary device of the present invention, when the terminal is plugged into the pattern generation program through the parallel port 12 from the PC 10 at the final presentation or inspection line of the LCD used in the mobile phone, the power supply is turned on. In the standby state (S 10). In the standby state S 10, the switch 250 is also turned on to set the LCD power, the pattern generation driver type, and the I / O setting.

Thereafter, the graphic pattern presentation driver is downloaded from the user with respect to the pattern generating program, and it is determined whether the tuning or the demo test event is provided through the rotary data interface 100 (S 12).

At this time, in the event providing determination step (S 12, when the graphic pattern presentation driver is downloaded, the PC 10 transmits data (S 11) to return to the standby state, and downloads the graphic pattern presentation driver. When receiving, if the user's event does not exist, the downloaded data is repeatedly performed. Meanwhile, if it is determined that there is an event of the next user who downloads the graphic pattern presentation driver, the start signal is transmitted to perform the tuning or demo test event. 200).

If the tuning or demo test event is started (S 12), the LCD is initialized to form a data path for transferring data downloaded from the PC 10 (S 14).

In the initializing step (S 14), the LCD is turned on using a Hitachi driver or another driver, and the frame size, synchronization (Sync and Pochi), and frame frequency of the horizontal / vertical / RGB are set.

After the initialization (S 14), by operating the graphic pattern presentation driver to form a data path to operate the rotary operation circuit 50 to mechanically rotate the rotary device up and down left and right at the same time rotate the rotary device up and down A command to make a command to the data interface 100 as data and a control signal (S16).

Here, the rotation of the rotary device rotates or rotates at a speed of 120 rpm up and down, left and right, and stops for about 1 second at a maximum angle of 80 degrees and then proceeds again. In addition, the still image is initialized when the switch 250 is turned on as described above, and about 20 still images are sequentially processed.

Thereafter, it is determined whether the graphic pattern signal operated by the CPU 200 in the step S16 is arranged at a predetermined front center position (S18).

If the switch 250 is operated by the switch 250 in the front position determination step (S18), the regulator 26 outputs the LCD presentation outside the allowable range commanded by the presentation controller 50 under the control of the CPU 200. Adjust the parameters of the pattern by deriving the allowable value through the determination. At this time, if it is determined that the reset switching to the reset operation in the front center position to feed back the event of the normal signal by the rotary data interface 100. On the other hand, if it is determined that it is not located in the front center (NO), it is fed back to the rotation and still image processing step (S16). And the rotary operation circuit 50 is VCC. By the regulator 26 to keep the load voltage within the allowable range. Adjust the VCI voltage.

In addition, if it is determined in the front position determination step (S18) is located in the front center (YES), by receiving a control signal from the rotary data interface 100 by a central processing unit (CPU, 200) to convert into a digital graphic pattern signal The video pattern is executed by processing the graphic pattern encoded from the output AD converter 22, that is, by operating the rotary operation circuit 50 to fix the rotary device at a predetermined position and simultaneously fix the rotary device (S). 20).

At this time, it is determined by the rotary data interface 100 whether the rotary operation circuit 50 waits for a predetermined timing time limit, for example, 10 seconds (S 22).

In this case, if the switching to the reset after 10 seconds has elapsed in the timing limit time determination step (S 22), it feeds back by the rotary data interface 100 to have an event again. In addition, if it is determined that the timing time limit is not within 10 seconds, the control unit feeds back to the exact position video processing step (S20).

On the other hand, when it is determined that the time limit is within 10 seconds in the timing limit time determining step (S 22), the rotary operation circuit 50 receives a control signal from the rotary data interface 100 by a central processing unit (CPU, 200). Stop) and executes the next image waiting for the still image (S24). At this time, the still image execution step (S 24) is repeatedly performed to determine the event of the user (S 12).

 Meanwhile, the logic function circuit 30 directly connects the CPU and the rotary operation circuit 50 equipped with the cellular phone LCD and the data bus buffer 32 to connect the RAM 210 and the ROM ( 221 and the EEPROM 230 are connected to the CPU to output a bypass signal of buzzer sound, vibration, and sound, and to receive a control command of the CPU 200 and to pattern the presentation controller 150. LCD display showing the driving state of the display.

As the above processes are continuously and sequentially and collectively, automation is possible.

Therefore, as described in detail above, the LCD device for inspecting the rotary pattern and the method of the present invention are provided with an LCD driver installed on the PC to present the image pattern of the LCD of the cellular phone, and the LCD presentation generated by the rotary data interface. The pattern can be detected in the right and left or up and down directions so that the viewing angle can be checked in any direction, to perform presentation tuning or demonstration, to eliminate the possibility that the viewing angle of the LCD pattern is distorted or further damaged, and to operate the rotary operation circuit. It is automatically rotated by the LCD pattern generation program, so the presentation is excellent at any viewing angle according to the model change.

In addition, the rotary device for inspecting the LCD pattern and the method automatically present the LCD pattern through the interaction of the CPU and the rotary data interface according to the result value detected from the presentation pattern. The measurement maintains the allowable pressure range to maintain uniformity of quality.

In addition, the rotary device for inspecting the LCD pattern and the method thereof do not change any presentation model required for each LCD pattern by a mechanical method when a parameter is changed by a driver that drives the LCD pattern of the mobile phone.
