During the use of high brightness display screens in storefronts, sometimes there may be missing or blurry graphics, which seriously affects the effectiveness of the display screen. So, what are the reasons for this phenomenon and how can we solve it? Below, the editor will analyze for everyone.
The product's garbled characters are divided into partial and full screen, and the left and right directions of the text are misaligned or skewed. The most common reasons are:
1. It may be caused by interference
2. It may be due to the DSP's suspension
3. If the film selection is reversed, first check whether the selection order of the film is correct. This is determined by following up on the product drawings and the interface of the product itself. Half of the products will indicate the first and last pins.
When encountering local and full screen garbled characters, first check if there is external communication. If there is, it must be eliminated. If not, we need to check if there is a 232245 circuit connected and remove these circuits, as they may cause interference and affect our product.
Secondly, it is also possible that the software timing is inconsistent with the enable angle of our window display. Some can install a 4H14 delay circuit on the timing lighting to delay processing on the enable angle.
Finally, for those external high-frequency interferences, we can perform some shielding processing on the display data line.
The above is the analysis of the reasons for garbled characters during the use of high brightness displays in storefronts introduced by the editor, hoping to provide reference and assistance to everyone.
