Νέα οθόνη 4” LTPS LCD της Toshiba, ξεπερνά τη Retina Display! Φήμες για χρήση σε μελλοντικά iPhone! [Update]

Από εχτές έχει ξεκινήσει η έκθεση SID 2011 (Society for Information Display) από την οποία θα πάρουμε μια γεύση για τις οθόνες του όχι και τόσο μακρινού μέλλοντος.

Toshiba Retina Display

Ισχυρή παρουσία είχε η Toshiba με τις νέες της οθόνες για smartphones, όλες τεχνολογίας LTPS LCD (low temperature polycrystalline silicon), με μεγέθη από 3.3” έως 4”, με την τελευταία να ξεπερνά σε ανάλυση και πυκνότητα τη Retina Display της Apple!

Συγκεκριμένα, η νέα οθόνη 4” της Toshiba αποδίδει 367ppi (pixels per inch) και ανάλυση 1280 x 720 (720p) με αντίθεση 1500:1, ενώ η Retina Display 326ppi και ανάλυση 960 x 640 με αντίθεση 800:1!

Ακόμη, η Toshiba παρουσίασε μια νέα τεχνική για καλύτερη απόδοση τρισδιάστατης εικόνας, σε οθόνες 3” (400 x 240) και 8” (800 x 480) για smartphones και tablets, η οποία ονομάζεται Time Sequential 3D και χρησιμοποιεί οπισθοφωτισμό με γρήγορη εναλλαγή του φακού από το αριστερό στο δεξί μάτι, έτσι ώστε να δημιουργεί εφέ glasses-free 3D διατηρώντας παράλληλα ζωντανή την εικόνα.

Σε αυτό το σημείο πρέπει να αναφέρουμε ότι η Apple χρησιμοποιεί οθόνες της Samsung στα προϊόντα της, αλλά φήμες λένε ότι η Toshiba ετοιμάζει νέα μονάδα παραγωγής αποκλειστικά για τα νέα iPhone, από το 2012 και έπειτα….

LOS ANGELES, Calif., May 16, 2011 – Toshiba America Electronic Components, Inc. (TAEC)*, a committed industry leader that collaborates with customers to create breakthrough designs, will exhibit next-generation displays and technologies developed by Toshiba Mobile Display Co., Ltd. (TMD)** for mobile phones and portable electronics, automotive applications, industrial markets and 3D applications in booth #1119 at the 2011 Society for Information Display (SID) International Symposium, Seminar & Exhibition, May 17 to 19, 2011.
Featured developments in TAEC’s booth this year include two different 3D technology demonstrations, new displays for high-resolution handheld mobile applications, high-resolution and high-reliability automotive displays and industrial LCD displays with replaceable LED backlights capable of 100,000 hours MTBF1. Displays with Low Temperature Poly-Silicon (LTPS), Optically Compensated Bend (OCB), System-on-Glass (SOG), LED backlighting, and other advanced technologies can be viewed in five demonstration areas: mobile, automotive, industrial, 3D, and SOG in-cell technology.
“We are excited to exhibit several new and innovative products and technologies aimed at mobile, automotive and industrial applications. Our advancements in system-on-glass in-cell technology and our approaches to 3D will enable future growth in new markets and applications,” said Clayton Bond, senior vice president, Display Devices and Components Business Unit for TAEC.

3D Technology
TAEC will demonstrate two 3D technologies. The first approach, Integral Imaging 3D, combines an ultra-high resolution display and a lenticular lens sheet to enable “Multi-view” natural viewing without 3D glasses, so the same image can be seen from multiple viewing points. Integral Imaging will be shown in a 21.0-inch Wide-XGA (1280 x 800) and 12.1-inch 466×350 technology demonstration. The second approach, Time Sequential, will be shown on two displays – a 3.0-inch Wide-QVGA (400 x 240) and an 8.0-inch Wide-VGA (800 x 480) 3D OCB panels – utilizing a backlight system incorporating a bi-directional lens sheet. The displays synchronize LED switching with left- and right-eye images to achieve stereoscopic (twin-eye 3D) viewing without special glasses while maintaining a fast response time and a wide viewing angle. This approach is 2D/3D switchable, and enables a thin, easy-to-assemble LCD panel utilizing its full native resolution without compromise.

In-cell Technology
TAEC will demonstrate two novel in-cell technologies enabled by LTPS technology. The first technology, in-cell touch, is based on capacitive coupling between the user’s finger and the detection electrode on the TFT substrate at a given point. This approach utilizes LTPS to integrate the capacitive sensors into multiple locations in the cell, and enables multi-touch operation with no touch force. The in-cell capacitive touch technology will be shown in a 7.0-inch Wide SVGA (1024 x 600) technology demonstration, and discussed in Seminar 43.4 on Thursday, May 19 at 10:00am in Petree Hall D. The second technology, in-cell write-erasable, is based on the integration of memory circuits and photo sensors into the display cell. This in-cell, write-erasable technology will be shown in a 7.0-inch QVGA (320 x 240) technology demonstration, and discussed in Seminar 50.3 on Thursday, May 19 at 11:20am in Petree Hall D.

Displays for Mobile Phones and Portable Electronics
The mobile section of the booth will feature high-resolution LTPS displays, up to 367ppi (pixels per inch) resolution density, in sizes ranging from 3.3-inch to 4.0-inch with resolution formats ranging from Wide VGA (480 x 864) to HD (720 x 1280). In addition, these displays will demonstrate advanced technologies such as high-contrast (up to 1,500:1), high-color (up to 92% NTSC), and wide viewing angle (up to H/V 176º/176º). The displays are just a few representative examples of TMD’s broad line of thin and light displays for mobile smartphones and other portable electronic devices.

Displays for Automotive Applications
Innovative displays for automotive center information, navigation and entertainment applications are also featured this year. A high-resolution 9.0-inch Wide XGA (1280 x 720) TFT module for HDTV automotive entertainment applications is featured, along with a 7.0-inch Wide VGA (800 x 480) TFT module with wide viewing angle for center information or navigation applications will be shown. Also, three other displays – a 5.0-inch Wide QVGA (480×240), a 4.2-inch Wide-QVGA (400 x 240) and a 3.5-inch QVGA (240 x 320) – designed for high-reliability instrument cluster applications will be demonstrated. Lastly, a 3.3-inch Wide-QVGA display, designed for rearview mirror application, will be shown, too.

Displays for Industrial Applications
A portion of TMD’s lineup of color LTPS active-matrix thin-film transistor (TFT) LCD modules for industrial applications will be shown, which incorporate 100,000 hour MTBF LED backlighting systems designed to satisfy the requirements of a broad range of industrial applications, such as test and measurement equipment, medical equipment, and more. Each module shown has replaceable, mercury-free2 LED-based backlighting systems with 100,000 hour MTBF, which far exceeds that of common TFT LCDs for industrial applications utilizing long-life cold cathode fluorescent lamp (CCFL) backlights. Additional modules include two 100,000 hour MTBF modules with resistive touch panels: 8.4-inch XGA (1024 x 768) and 10.4-inch XGA (1024 x 768) LCDs, with replaceable LED backlights.
