Imagine you were dragging on a rubber sheet instead of the LCD screen. The sheet would stretch out a bit behind the stick and bunch up slightly in front. The pattern would look exactly like what you're seeing on the LCD. A LCD screen works by changing the polarization of light as it passes through a very narrow gap between 2 plastic sheets. This gap must be ...

https://en.m.wikipedia.org/wiki/LED-backlit_LCD LCD transmissive displays are either diffused edge-lit or back lit. The edge lit are spot LEDs on 1 or 2 sides constrained into the edge of the glass by U metal brackets with diffusion plastic layers between glass and crystal layer to spread the backlight evenly. For large LCD screens they use large diffused ...

An LCD doesn't emit light. It either has a reflector behind it, or a separate light source (backlight). The backlight may be controllable on any scale from a monolithic whole to a pixel. The LCD selectively blocks light. In a color LCD, each pixel will have 3 segments which correspond to red, blue, and green filters. Color is achieved by blocking these ...

Usually, these type are soldered to pcb directly.Standart FPC/FFC do not have Vias on the gold fingers. These are soldered directly to a matching footprint on the pcb. You have the following options: Ask Manufacturer for mating connector Try to cut the pcb to match a standart connector Buy a standart 14-pin cable assembly and solder it on the pcb, then ...

It's also to do with supply chain. A component you buy on digikey or RS etc has a very significant price overhead attached to it. You are paying for the convenience of the supplier (digikey or RS) cataloguing items, packing, shipping, A finished LCD monitor as product can benefit from all the advantages of volume production and the efficiency that comes ...

Looking at the timing diagrams for the two devices: Horizontal HSYNC0 appears to equate to the front porch timing. HSYNC1 is the total time for for HSYNC and HSYNC will be driven low for HSYNC1 - HSYNC0. For your display (which wants a single clock) this means that HSYNC1 should be HSYNC0 + 1. HCYCLE appears to be the number of clocks for a complete ...

If you have a COG (chip on glass) LCD controller, then it is no way even possible to guess the controller. If you have the original product as well from where the LCDs were savaged, you can plan to use a logic bus analyser to monitor the waveforms. Even there it will be impossible to decode the signals into useful information. If the original circuit has the ...
