Description
Technical field
The present invention relates to a kind of framework, refer to a kind of test structure of testing for the display of various variety classeses, size especially with signal generator test display.
Background technology
Existing with LCD MODULE (LIquid Crystal Module; Hereinafter to be referred as LCM) the framework system of signal generator test LCM is as shown in Figure 2, it is to connect LCM signal generator 82 with a control computer 81, connect tested LCM83 by LCM signal generator 82 again, and transfer to LCM signal generator 82 by the image of control computer 81 selected tests, and by built-in image standard signal format library 821 (as: digital image interface DVI, the monitor data communication DDC of LCM signal generator 82 ... Deng) the middle transmission interface of selecting to be fit to tested LCM83, to export adaptive signal tested LCM83 is carried out image test.
Yet, existing LCM signal generator 82 built-in image standard signal forms 821 all are confined on large-sized LCM, and do not support 80/68, action industry processor interface (MIPI) data transmission and RGB interface (Interface) data transmission, more inapplicable for the LCM of colored small-medium size.
Because its module model of the LCM of colored small-medium size is of a great variety, and the input signal of its drive IC of the LCM of different vendor or model (Driver), control buffer, address area are not quite similar, before testing, must then need write initialize routine if use traditional tool to do the LCM test prior to loading required driver in the LCM signal generator 82 by the professional.Existing mode with LCM signal generator test LCM is inconvenience completely, and especially for the manufacturer of the various colored small-medium size LCM of professional production, therefore trouble has in addition improved necessity especially.
Summary of the invention
The purpose of this invention is to provide a kind of more full of elasticity and convenient framework that uses with signal generator test display.
For achieving the above object, the present invention takes following design proposal: a kind of framework with signal generator test display, it has a control computer, be provided with a signal software interface in this control computer, but have the control of the flow process in proper order rule of initialization display drive IC in this signal software interface, send via this control computer to provide various test datas by this signal software interface; This control computer is connected with a signal generator, have a database with driver of different driving IC in this signal generator, mourn selected corresponding driver after this signal generator receives the test data of this control computer transmission, and this signal generator is connected with the transport interface of different size, is connected with signal generator with the display that the different size kind is provided and tests
Advantage of the present invention is: can supply the display of various variety classeses, size to test easily.

Embodiment
As shown in Figure 1, the present invention is with LCD MODULE (Liquid Crystal Module with the framework of signal generator test display; Hereinafter to be referred as LCM) be the example explanation, this framework has a control computer 1, be provided with a signal software interface 11 in this control computer 1, but have the control of the flow process in proper order rule of initialization LCM drive IC in this signal software interface 11, so that the test data of required image, color and resolution of test to be provided by this signal software interface 11, in order to do sending various test datas by this control computer 1.
This control computer 1 is to connect a LCM signal generator 2, have a database 21 with driver of different driving IC in this LCM signal generator 2, and this LCM signal generator 2 is connected with different size transport interface 22, the specification of this transport interface 22 comprises 80/60, MIPI, parallel port (ParallelInterface), I2C, SPI and rgb interface (RGB Interface) etc. are for the LCM3A of different size kind, the 3B interface format is connected with LCM signal generator 2 via transmission interface 22 and tests in order to do receive after the test data that this control computer 1 sends selected corresponding driver in this LCM signal generator 2.
See also Fig. 3, it is the window picture of signal software interface used in the present invention, and the method for operating of this signal software interface is as follows:
1. the user comes the specification file of opening module model according to display module to be measured, the signal software interface automatic introducing of meeting " driving type ", " resolution " reach the setting value of " number of colours ", the user just can open the image or the photo archive of test afterwards, carries out " transmission " again and tests.
2. PC is independent to be tested by signal generator if will break away from, and please select " program updates " that driving data is downloaded in the database in the instrument.
3. the user is tested if will set up new module model, then can comply with and insert initialized register values of IC (Register Value) and time delay (DelayValue) and configure " driving type ", " resolution " and [number of colours] according to the drive IC Spec. of this module to be measured, after finishing input, the user can carry out the demonstration test of R, G, the transmission of B color, can carry out " storing module model in addition " as if testing successfully this specification setting value is stored, so that direct in the future opening module model specification file is tested.
Because the specification of the LCM of colored small-medium size, can simply be divided into driver (Pure Driver), driving and controller (Driver ﹠amp according to the difference of drive integrated circult (Driver IC); Controller) two kinds, the specification of driver wherein (Pure Driver) has CIF, QVGA, VGA, XVGA, SVGA ..., its color-resolution depends on the signal of peripheral control unit (External Controller) and general standard signal generator; And drive and controller (Driver ﹠amp; Controller) specification then has 128 * 128,120 * 160,132 * 132,96 * 64,132 * 176 ... Deng the integrated circuit (IC) of supporting different chromatic filters (color filter) structure, wherein can be divided into again: 256 looks, 4K look, 65K look, 262K look etc., add the difference of different vendor's design, make that the specification of LCM of colored small-medium size is various, the contained real one size fits all that is difficult to of framework of testing LCM with the built-in image standard signal form of LCM signal generator in the prior art.
The present invention is directed to the various problem of LCM specification of colored small-medium size, be the transport interface 22 that will connect LCM signal generator 2 is designed to comprise 80/60, the transmission interface of parallel port (Parallel Interface), I2C, SPI, MIPI and rgb interface different sizes such as (RGB Interface), for being connected with the LCM of various different sizes, and cooperate the built-in driver database 21 of LCM signal generator 2, make LCM signal generator 2 can produce the test signal that adapts to tested LCM, so that test.
Moreover, for can Validity Test the function of LCM of all size, for example: its color of LCM, the resolution that drive with Pure Driver are the signal that depends on the standard signal generator, therefore the present invention is provided with signal software interface 11 in control computer 1, this signal software interface 11 has a piece of wood serving as a brake to halt a carriage body update functions, so that the test data of required image, color and the resolution of test to be provided, and can carry out Full Featured test to various LCM.
In sum, the present invention can reach easily the effect that the LCM for various colored small-medium sizes tests with the framework of LCM signal generator test LCM.
Certainly, the present invention is with the framework of signal generator test display, except as described above example applies to the LCM, also can apply on the organic light emitting display (OLED), and can reach the effect identical with previous embodiment.
