https://www.reddit.com/r/PSP/comments/cyfuod/psp_lcd_comparison_and_some_stuff_about_the/

I wonder why no one did this before. All of this is simply based on looking up the actual datasheets instead of just going with side-by-side comparison. Also, this is my first time writing a long post on reddit, so my apologies if I messed up the formatting.

So I took apart all the different PSPs I own and wrote down the model numbers of the LCD panels. Here is a list of the LCD panels used:

PSP 1000: Sharp LQ043T3DX01 to ...03 (Datasheet: https://www.sparkfun.com/datasheets/LCD/LCD-08335-1.pdf)
PSP 2000: Sharp LS043T3PX01 or ...02
PSP 3000: Sharp LQ043T3LX01 to ...03 (Datasheet: http://www.beyondinfinite.com/lcd/Library/Sharp/LQ043T3LX02.pdf)
PSP N1000: Sharp LQ038T3LX01
PSP E1000: AUO A043FW05 v8 (Datasheet: https://datasheet4u.com/datasheet-pdf-file/933222/AUO/A043FW05-V8/1)

I wrote down the most important stuff:

MISCELLANEA:

The panels used in the 1000, 3000 and E1000 series seem to be off-the-shelf parts that have also been used in many other devices (even touchscreen versions of these exist, for example for use in a GPS navigation system). The panels used in the 2000 and N1000 (PSP Go) series seem to be exclusive to the PSP, so you can't find datasheets for these.

Other versions of the PSP 1000 panel exist (up to ...07), but they have a differently specced backlight which uses higher current while operating at a lower voltage, so you can't simply put them into a PSP.

Other versions of the PSP E1000 panel exist as well (v0-v7), but these are also different in several aspects (touchscreen, different connector etc).

The PSP Go Panel seems to be exclusive to the PSP Go (so no datasheet is available), but the model number is exactly the same to the 3000 display besides the 38 instead of 43, which just describes the screen size (3.8 inches instead of 4.3 inches), thus making it very likely to have the same specs as the PSP 3000 panel in every other aspect. It also uses the exact same T-CON IC (sharp LR388GI, see below).

The Sharp LQ-panels are normally white, while the LS-panel from the PSP 2000 is normally black, going by sharps nomenclature used for their other panels. The AUO Panel is normally white.

The PSP 1000 uses parallel communication (40 pins) to the LCD; it doesn't seem to have a dedicated T-CON IC.
The PSP 2000 and 3000 screens have a serial connection (that's why the flex cable is much smaller and has less pins) and use a sharp T-CON IC (which is also shown with some schematics in the LQ043T3LX0 datasheet)(LR388A0 in the 2000, LR388G1 in PSP 3000 and Go).
The PSP E1000 screen uses a parallel connection (45 pins) again. There is some proprietary OKI IC on the board to drive it. The flex cable might be thin, but it has two rows of pins.

CONTRAST:
Pretty simple list here.

PSP 1000: 400:1
PSP 2000: ? (most likely similar to 1000)
PSP 3000 (and most likely also Go): 1500:1 (!)
PSP E1000: 400:1 (just like the 1000)

BRIGHTNESS:
Pretty simple list here again.

PSP 1000: 165 cd/m² when backlight is driven with 18mA
PSP 2000: ? (seems similar to the E1000, noticeable brighter than 3000 or 1000)
PSP 3000 (and most likely also Go): 200 cd/m² (with 18mA)
PSP E1000: 600 cd/m² (when driven with 20mA (!), which the PSP probably does not do )

The PSP 1000 official specs say up to 200 cd/m² (or 180 on battery) , since the PSP can drive the backlight with more than 18mA. However, by looking at the brightness at a specific current, you can easily compare between panels.

Color space:

PSP 3000: 85% of the NTSC color space
PSP E1000: 50% of the NTSC color space

Sadly, the other datasheets don't have any specs for this. I assume that PSP Go has the same color space as the 3000 and that 1000 and 2000 have a comparable color space to the E1000.

REACTION TIME:

PSP 1000: 30ms rise, 30ms decay --> 60ms black to black
PSP 2000: ? (most likely similar to 1000)
PSP 3000 (and most likely also Go): 16ms rise, 8ms decay --> 24ms black to black
PSP E1000: 15ms rise, 20ms decay --> 35ms black to black

The PSP 3000 display is by far the fastest display here.

Please note that black to black is different from the grey to grey time you find on most modern screens. Grey to grey is always lower than black to black, which is why it is used for advertising nowadays. There is no way to convert between black to black and grey to grey.

SUBPIXEL ALIGNMENT and "INTERLACING"/"SCANLINES":
The panels found in 1000, 2000 and E1000 have the subpixels horizontal to each other, so you get a vertical stripe of same-colored subpixels from top to bottom.
The panels found in 3000 and Go have the subpixels vertical to each other, so you get a HORIZONTAL stripe of same-colored subpixels.

Please note that this is (other than stated in many places) definitely NOT the only reason for the infamous "interlacing" effect, since the other models would have "vertical interlacing" in that case, which they don't.

IN FACT, when capturing the PSP 1000 screen or just looking close enough, you can see the interlacing effect there as well. It's just not as noticeable, mostly due to the lower contrast and slower reaction times "blurring" the effect to being almost invisible, which would mean that sony was right when they called the effect on 3000 a "feature".

Also, on PSP 3000 and Go, when looking at a still image while moving your head up and down, you can also see "interlacing lines" wandering over the screen from top to bottom. And a very similar effect can be achieved on many Nintendo devices using almost the same panels, like many DS lite. These have a potentiometer for each screen, and rotating it just a little bit in any direction causes the exact same "interlacing" effect.

I want to cite a post from shmups.system11.org:

"An LCD pixel element rotates between 0 degrees and 90 degrees, with one side representing full opacity and another full transparency (which being a property of the polarizer orientation). However, similar to any object that is repeatedly bent in one direction, it can get a little "stuck" towards a position it has been rotated towards a lot (I think because of capacitance, but the exact reason is beyond my understanding). To mitigate this, nearly every active-matrix LCD actually inverts the rotation direction every other refresh.

So, on frame 1, it'd be a swing from 0 to 90 degrees.
On frame 2, though, it'd be from 0 to -90 degrees.

The end result for both sides is actually the same, since it's just gating light. However, this is a precise task, perfectly inverting the swing of the rotation. Without this swing, "ghosting" effects can take place, as the crystal element gets a bias towards a rotation. [...] The GBA and GBC LCDs invert by line. Many small TFTs use this pattern. When you adjust that balance potentiometer, an effect that looks much like interlacing takes place, as the effects of the misbalance become visible on a per-line basis, and it changes between even and odd lines every frame. In this situation, the contrast can become a bit worse, too." (source: https://shmups.system11.org/viewtopic.php?f=6&t=63748)

The same is also true for the PSP. However, it doesn't have a potentiometer to adjust this. Instead, this effect just becomes VERY noticeable due to the high contrast and fast reaction times (and probably because it's not individually adjusted to each console due to the lack of a potentiometer). All of this is probably done by the sharp LR388* IC and was beyond sony's control.

PSP 1000 and 2000 just have too slow and low-contrast panels, which hide that effect. PSP E1000 also has a lower contrast and slightly slower reaction time and probably also just has smaller tolerances due to it being a newer device, which might explain why this effect is absent from here. This leaves the PSP 3000 and the PSP Go, however, the effect is less noticeable on the latter because the screen is simply smaller.

Feel free to look for errors or to search for the PSP 2000 and PSP Go display data sheets.
