The meaning of the landlord's post is actually not straightforward. The pixels of z3s and z4x are actually how they return. Why use diamond-shaped pixels to arrange them? It's more complicated than it really is. I'll be a simple science man.
First of all, let's take a look at the number of arrays of this 0.45 chip. The official data is 1140912. It's very odd, so compulsively point-to-point, I'm sorry, 1280800 is absolutely impossible.
Then, let's take a look at the pixel problem. This is the focus of the debate. Why does the landlord say 640,480? In fact, the landlord understands simplification, because we have been talking about the calculation of the diamond pixel plus difference, but it is not The principle of simple half of real resolution is reduced by half.
I now use cad to simply rank the 16:10 resolution ratio.
As shown in the figure, a white rectangle rotated 45 degrees is a diamond-shaped pixel point, a green circle is an odd-numbered row center point, a red circle is an even-numbered row center point, and a yellow extension line is a resolution.
This is very clear, in fact, we use the number of pixels is 810, and we get the resolution is 1610, half the pixels to save the effect. . .
Finally, we take a look at the schematic of the official dlp4500 chip technical documentation!
General Features
Stable Quality & High Reliability
Starlight Battery is well-known for its stable and reliable performance.Starlight batteries are easy to maintain; thus,permitting a safe and proper operation of theequipment that the battery powers. The battery can withstand overcharge, over discharge,vibration, and shock.It is also capable of extended storage.
Sealed Construction
Starligh's unique construction and sealing technique guarantees that no electrolyte leakage can occur from the terminals or case of any Starlight's battery. Thisfeature insures safe and efficient operation of our batteries in any position. our batteries are classified as "Non-Spillable" and will meet all requirements of the International Air Transportation Association.
Long Service Life, Float or Cyclic
The Starlight Vrla Battery has a long life in float or cyclic service. The expected life of float service is 18 years @ 25℃.
Maintenance-Free Operation
During the expected float service life of Starlight batteries, there is no need to check the specific gravity of the electrolyte, or add water. In fact, there is no provision for these maintenance functions.
Low Pressure Venting System
Starlight batteries are equipped with a safe low pressure venting system,which operates from 1 psi to 6 psi.The venting system is designed to release excess gas in the event that the gas pressure rises to a level above the normal rate.Afterwards,the venting system automatically re-seals itself when the gas pressure level returns its normal rate.This feature prevents excessive build up of gas in the batteries. This low pressure venting system, coupled with the extraordinarily high recombination efficiency, make Starlight batteries the safest VRLA Batteries available.
Heavy Duty Grids
The heavy-duty lead calcium-alloy grids in Starlight batteries provide an extra margin of performance and service life in both float and cyclic applications, even in conditions of deep discharge.
Low Self Discharge
Because of the use of Lead Calcium grids alloy, Starlight VRLA battery can be stored for long periods of time without recharge.
