Detailed Description
In order to make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Along with the rising of display device demand day by day, the module developer is also higher and higher to display module's detection technology, in order to reduce check-out time and cost, often need detect the multi-disc display module simultaneously, in order audio-visual performance testing result, need distinguish the demonstration to show that the module that the testing result is ineligible and other normal modules is directly perceived to embody bad module.
In order to solve the above problem, an embodiment of the present application provides a device for identifying a state of a module to be displayed, where the device sends a first image to the module to be displayed when receiving first state information of the module to be displayed, so that the module to be displayed displays the first image;

wherein the first image is different from the second image;
in some embodiments, the first image is an image of an embedded character; the second image is an image in which no character is embedded.
For example, when the module to be displayed is detected as an unqualified module, the device sends an image embedded with characters to the module to remind a detector that the detected module is an unqualified product. The device can improve the detection quality of the display module, and the hardware structure of the equipment is simple and easy to realize.
It should be noted that the specific content of the character in the image of the embedded character can be set at will, and the embedded character only serves as a mark.
Before an image is sent to a module to be displayed, in order to better match the display module, a series of processing is generally required to be performed on the image, and therefore, in some embodiments, as shown in fig. 1, the apparatus for identifying the state of the module to be displayed further includes: the image processing device comprises a bus control unit, a first image processing unit, a second image processing unit and an image output unit.
The bus control unit controls the first image processing unit, the second image processing unit and the image output unit to work according to the received state information of the module to be displayed, the resolution ratio of the display module and other information.
For example, when the module to be displayed in fig. 1 is detected as an unqualified product, the bus control unit controls the first image processing unit to perform matching processing on the image size of the first image, the size of the embedded character and the resolution of the image according to information such as the resolution information of the module to be displayed and the screen display size of the display module, and the information is output to the module to be displayed through the image output unit to be displayed.
When the module to be displayed in fig. 1 is detected as a qualified product, the bus control unit controls the second image processing unit to perform matching processing on the second image, and then the second image is output to the module to be displayed through the image output unit to be displayed.
When the image processed by the image unit is displayed on the display module, the image can be clearly displayed, and the state of the module can be conveniently recorded by detection personnel.
To implement the processing procedure for the image in the foregoing example, in some embodiments, as shown in fig. 2, the first image processing unit includes: the device comprises a first image reading module, an image compression module, an image cache module, a character processing module and an image amplification module;
the work flow of the first image processing unit is as follows:
the first image reading module reads a first image in an external memory and sends the read first image to the image compression module;
the image compression module performs image compression processing on the received first image and sends the compressed first image to the image cache module for caching;
the character processing module is used for amplifying or zooming the characters embedded in the first image stored in the image cache module;
the image amplification module performs image amplification processing on the first image stored in the image cache module.
It should be noted that, in the present application, the first image and the second image are generated according to information such as resolution of the display module, a size of a screen (a size of a screen), and the like, and have reached a requirement suitable for displaying in the display module before being processed by the image processing unit, the first image needs to be reprocessed according to factors such as a size of a character to be displayed in the display module due to the embedded character, the image compression module stores the compressed first image in an image cache module of the device itself, which is convenient for the character processing module to retrieve, and meanwhile, the compressed image is more convenient for the character processing module to process characters in the first image, and the image amplification module restores the compressed image to a state before compression.
Since the detected modules to be displayed are detected by a plurality of display modules simultaneously, as shown in fig. 3, in some embodiments of the present application, the second image processing unit includes:
the device comprises a second image reading module and a time sequence generating module.

the second image reading module reads a second image in the external memory;
the time sequence generating module generates a time sequence signal corresponding to the display position of the module to be displayed and associates the generated time sequence signal with the second image to realize the display on a specific display module piece.
For example, as shown in fig. 3, when it is detected that the detection results of the to-be-displayed modules 1, 2, and 3 are qualified, since the single display module is a qualified product, the 3 display modules all need to display the second images, and therefore, the timing generation module generates the corresponding timing signals according to the attribute information of the 3 display modules and associates the timing signals with the 3 second images respectively, so as to ensure that the 3 images can be displayed at the corresponding positions.
It should be noted that, when the first image is displayed at the position of the specific module to be displayed, the first image may also be associated by loading a timing generation module in the device, but it should be clear to those skilled in the art that after the second images are generated and displayed at the specific position of the module to be displayed, the module which does not display the image should display the first image, that is, by using an exclusion method, the module to be displayed which does not display the image after excluding the module piece which displays the second image in the module to be displayed displays the first image is displayed.
In order to further simplify hardware equipment, the device for identifying the module to be displayed can be realized by burning a corresponding program on an FPGA chip.

A Field Programmable Gate Array (FPGA) is a programmable device that has a different structure than traditional logic circuits and gate arrays (such as PAL, GAL and CPLD devices). The FPGA utilizes small lookup tables (16 × 1RAM) to realize combinational logic, each lookup table is connected to the input end of a D flip-flop, and the flip-flops drive other logic circuits or drive I/O (input/output) circuits, so that basic logic unit modules capable of realizing both combinational logic functions and sequential logic functions are formed, and the modules are connected with each other or connected to an I/O (input/output) module by utilizing metal connecting wires. The logic of the FPGA is implemented by loading programming data into the internal static memory cells, the values stored in the memory cells determine the logic function of the logic cells and the way of the connections between the modules or between the modules and the I/O and finally the functions that can be implemented by the FPGA, which allows an unlimited number of programming.
