Description

LCD module flicker Burning device

technical field

The utility model relates to a Flicker burning device for a liquid crystal module.

Background technique

During the production process of LCD modules, there will generally be some display differences. The specific phenomenon is that the flicker ratio is different, and some will flicker severely, making the display of the LCD module blurred and affecting the display effect. In order to solve the above problems, it is necessary to adjust the LCD The module performs Flicker programming. At present, the probe is usually placed directly on the LCD module when performing Flicker programming. Because the probe itself has a certain weight, when the probe is pressed on the LCD module, it is easy to make the probe and the LCD module The contact part of the group turns white, so that the burning effect is not good. Another method is to place the probe horizontally upward. When burning, turn the probe vertically and place the probe above the LCD module. Facing the liquid crystal module, when using this method, because the probe is easy to accumulate dust when the probe is placed horizontally upward, the burning effect is not good.

Utility model content

The technical problem to be solved by the utility model is to provide a Flicker burning device for liquid crystal modules with high burning quality.

In order to solve the above-mentioned technical problems, the liquid crystal module Flicker programming device provided by the utility model includes:

A base, the upper surface of the base is provided with a groove for placing the backlight source and the liquid crystal module;

A display drive box for lighting the liquid crystal module;

A horizontally rotatable probe box arranged on the base, on which is provided an optical probe for detecting the flicker value of the liquid crystal module and a display for displaying the programmed value and the corresponding flicker value screen, the optical probe is located at the bottom of the probe box, the probe box can be rotated horizontally to switch between the first state and the second state, when the probe box is in the first state, the optical probe is located above the groove, and the probe box is in the second state , the probe box moves out of the top of the groove.

Preferably, the probe box is provided with an indicator light for flashing during programming and to stop flashing after the programming is completed.

Preferably, the base is provided with a fixed seat, and when the probe box is rotated to a position against the fixed seat, the optical probe is located above the groove.

After adopting the above structure, the utility model has the following advantages compared with the prior art:

In the utility model, the probe box adopts the method of horizontal rotation. When burning is required, the backlight source is placed in the groove, and then the liquid crystal module is placed on the backlight source, and then the display drive box is connected to the liquid crystal module. Connect it so that the display driver box lights up the LCD module, then turn the probe box horizontally so that the optical probe is placed above the LCD module, and then start burning. After the burning is completed, the burnt Burning value and corresponding Flicker flicker value; after adopting the LCD module Flicker burning device of the present utility model, since the probe is not directly placed on the LCD module, the LCD module will not be whitened, and the probe box adopts horizontal rotation In this way, the optical probe is always located at the bottom of the probe box, so that it is not easy to accumulate dust on the optical probe, which makes the measurement of the flicker value of the liquid crystal module by the optical probe more accurate, thus making the programming quality higher.

Description of drawings

Fig. 1 is a structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in FIG. 1 , the Flicker burning device for liquid crystal module of the present invention includes a base 1 , a display drive box 4 for lighting the liquid crystal module, and a probe box 3 arranged on the base 1 which can rotate horizontally.

The upper surface of the base 1 is provided with a groove 101 for placing the backlight and the liquid crystal module. When burning, the backlight is placed in the groove 101, and then the liquid crystal module is placed on the backlight. Then the liquid crystal module is turned on through the display drive box 4 .

The probe box 3 is provided with an optical probe for detecting the flicker value of the liquid crystal module and a display screen 303 for displaying the programmed value and the corresponding flicker value. The programmed value is the VCOM of the liquid crystal module. Voltage, the optical probe is located at the bottom of the probe box 3, the probe box 3 can be rotated horizontally to switch between the first state and the second state, when the probe box 3 is in the first state, the optical probe is located above the groove 101, the probe box 3 When it is in the second state, the probe box 3 moves out of the groove 101. At this time, it is more convenient to place the backlight and the liquid crystal module in the groove 101.

The burning process is as follows: real-time detection of the flicker value of the liquid crystal module by an optical probe, and then adjusting the VCOM voltage of the liquid crystal module. When the VCOM voltage is adjusted, the flicker value of the flicker changes in real time. When the value is set, the VCOM voltage at this time is burned into the liquid crystal module, so that the display effect of the liquid crystal module is better.

Described probe box 3 is provided with an indicator light 302 that is used to flicker when burning and stops flickering after finishing burning, and probe box 3 is provided with drive plate 301, and drive plate 301 is connected with optical probe, indicator light 302 respectively. It is connected with the display screen 303 , and the driving board 301 is used to control the operation of the optical probe, the indicator light 302 and the display screen 303 .

The base 1 is provided with a fixed seat 2. When the probe box 3 is rotated to a position against the fixed seat 2, the optical probe is located above the groove 101. In this way, when programming is required, only the probe box needs to be 3 Just turn it to the position where it is in contact with the fixed seat 2, so that it is convenient to position the probe box 3, so that the probe box 3 can be rotated to the desired position more conveniently.

The above is only a description of the preferred examples of the application of the utility model, but it should not be understood as a limitation on the claims. The structure of the utility model can have other changes and is not limited to the above structure. In a word, all the various changes made within the scope of protection of the independent claims of the utility model are within the scope of protection of the utility model.
