Description

[Technical Field] The present invention relates to a picture detecting device and a detecting method thereof, and more particularly to a flat panel display (FPD) face detecting device and a detecting method thereof. [Prior Art] With the wide application of flat panel displays, users' requirements for video quality are also increasing. High-definition and high-performance flat panel displays must accurately handle the various input and output signals. Currently, in order to achieve higher video standards, the picture performance of a flat panel display needs to be detected by a pattern generator. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the structure of a face detecting device of a prior art liquid crystal display. The product pre-detected by the face detecting device i 0 is a liquid crystal display module 15. The liquid crystal display module 15 includes a driving integrated circuit (Drive

Integrated Circuit 151 and one of the liquid crystal display panels 152 driven by the drive integrated circuit 15ι. The face detecting device 1A includes an external power source U, and a pattern generator 13' which supplies an operating voltage to the pattern generator 13. The graphic generator 13 provides a test signal to the liquid crystal display module 15. The picture generator 13 of the picture detecting device 1 includes a power conversion device 131, a memory 132, a micro processing unit 133, an input/round interface 134, and a control interface I%. The power conversion device ι31 converts the voltage from the external power source 11 into the operating voltage required by the pattern generator 13 and the liquid crystal display module 15. The memory 132 stores a liquid crystal display 6 1315150 screen detection program. The program includes graphics generation and timing output. = Accurate μ displays the operation of the color and position information required for each pixel. The control interface 135 is composed of a plurality of complexes, and the memory 132 stores the parameter values of the program for the row to operate. The micro processing unit 133 accurately transmits the signal data required by the liquid crystal display module 15 according to the memory storage program and the parameter value input by the control interface 135, and the (4) (four) ^

The input/output interface 134 is transferred to the body circuit 151 of the liquid crystal display module 15. During the detection of the m, the micro processing unit 133 calculates the signal data for driving the liquid panel 152 according to the stored value of the memory 132 and the parameter value input by the control interface 135, and then via the input/output interface 134. The signal data is transmitted to the driving integrated circuit i5i so that the liquid crystal display panel 152 displays the surface, and the surface performance of the liquid crystal display module 15 is detected by the display screen. φ However, at the time of detection, the user 胄 manually adjusts the knob of the control interface 135 of the graphic generation H 13 to set the test item and the parameter value. Moreover, when adjusting, the adjustable range of the knowledge is limited. For example, when the common image generator 13 adjusts the width of the public line and the number of gray levels, it can only achieve a certain number of bus widths (the setting is aging) and gray. The number of classes (usually set to 1 〇), and when setting the color cedar, only the eight colors of the combination of red, blue, and green ternary colors are output. Therefore, when the test item and the parameter value are set by manually adjusting the knob, the test item detection (4) of the set is small, the high-precision detection requirement cannot be realized, and the set parameter value also has a certain error with the ideal parameter value. , 7
