psone lcd screen repair made in china

China, we’re told, can make anything. If you need some PCBs in a few weeks, there are a few factories in China that will do it. If you need a nuclear reactor, yep, there’s probably a factory in China that’ll do it because nuclear reactors are listed as one of the items facing new tariffs when imported into the United States. No, I am not kidding. What about LCDs? What about old-school character LCDs? Is it possible to find a factory in China that will make you the LCD you want? That’s what [Robert Baruch] will find out, because he’s repairing an old computer with new parts.

The object of this repair and restomod is a TRS-80 Pocket Computer (PC-1), otherwise known as the Sharp PC-1211. It looks like a calculator, but no, it’s a legitimate computer you can program in BASIC. [Robert] bought this computer for a bit more than $5 on eBay ‘for repair’, which means the zinc-air battery was dead, and unfortunately, the LCD was shot. The LCD technically works, but it just doesn’t look good. Sometime in the last thirty years, moisture got in between the layers of glass, polarizing film, and liquid crystal. This is not unique to [Robert]’s unit — a lot of these PC-1s have the same problem, many of these broken seals rendering the computers themselves useless.

This is an ancient computer, and replacements for this LCD are impossible to find, but because the Sharp PC-1211 is well documented, it is possible to find the datasheet for the original display. With that, it’s just a question of finding an LCD manufacturer that will do it. So far, the costs look good — $800 USD ($300 for tooling and 10 samples, $500 for another 200 LCDs) is what it’ll take to get a few units. [Robert] already has a few people interested in repairing their own Pocket Computers. You can follow the eevblog thread here, or check out the video below.

Soul Reaver’s soundtrack often gets a lot of acclaim. Even though it could have been simple to include pre-recorded CD audio on a PlayStation game, Soul Reaver actually uses a high-quality sequenced audio (similar to the SNES) that could dynamically altered and shifted based on what is happening on the screen. The Crystal Dynamics team was able to create a soundtrack of phenomenal quality while taking up very little storage space on the disc.  DF Retro’s 36 minute Soul Reaver video digs into some of these.

For Crash 2, the team at Naughty Dog rewrote approximately 80% of the game engine and tool code based on the lessons they learned and the bottlenecks they saw in the first game. In the end, Crash 2 aimed for twice as much on the screen while maintaining the 30 frames per second. It also added more effects such as Z-buffer-like water effects, weather, reflections, particles, talking hologram heads, etc.

On top of the already impressive game, Driver also featured a Director Mode that let the player shoot and cut their own mini car chase movie with a simple, freeform camera system. Most modern games have a similar camera, but it’s mostly for internal purposes of taking media screenshots and trailers. However, touches like this showed that the team at Reflections had a real passion for creativity, maxing out the hardware, and making people take notice.

In a shmup, you ideally want to see as much detailed destruction on your screen as possible, without any slowdown. Einhander delivers on those dreams in full polygonal glory. (This shooter has polygons, but the environment is not fully 3D and the gameplay is still true to the 2D roots) Einhander, for the most part, flies by at a solid 60 frames per second, however there are some minor slowdown issues once things get hectic with 20+ enemies on the screen at once.

Alone in the Dark the New Nightmare – While having some dark and gloomy atmosphere, the game shows some innovation with its flashlight’s aesthetic effect. As the game’s environments are prerendered 2D paintings, their being lit in real-time seems rather confounding. Darkworks used a technique called “meshing” to render the environments. Meshing entails rendering two versions of each environment–one lit and one unlit. When a character shines the flashlight on any particular part of the environment, the lit version of that fraction is displayed. It’s very neat to behold, and the effect is quite impressive–you’d swear it was all done in real-time. The animation is spot on, with some lovely lighting effects and tremendous detail given the ailing PSOne hardware. The colour is surprisingly rich too, unlike other survival/horror games where an absence of life usually means an absence of detail.

Regarding Wipeout 3, at least the SE European version has another ace up its sleeve: it’s one of only about two PS1 games to feature simultaneous spilt-screen and link capability for four players. That was a lot of fun!

When video is interlaced every single frame consists of two fields to being displayed on analog CRT tv screen – odd and even. And every single field needs exactly 1Hz (one refresh of a tv screen). So If a game runs at 50 or 60 fps WITH intrlaced resolution it needs 100Hz or 120Hz tv for even being able to be displayed as 1 fps needs exactly 2Hz. And 99% of tv set back than (late 90’s, early 00) has only 50Hz (PAL) or 60Hz (NTSC).

That’s why the simplest way to imagine how interlaced signal works is that within single frame it only displays one field of lines (odd) and that’s all. Next, within second frame it displays a field of even lines. Since first set of lines, I mean first field, is still on the screen it “meets” the second set of lines from the next frame. That’s why every frame in interlaced video consist of two fields which always come from two different native frames generated by console.
